 Grado RA1 Reference Desktop Headphone Amplifier (Battery) at 21542.00 PHP from TREOO.com
Grado RA1 Reference Desktop Headphone Amplifier (Battery)
₱ 21,542.00
TREOO.com
After years of relying on other equipment to drive Grado headphones, you can now listen and enjoy headphones through our new Grado Reference Headphone Amp, the Ra1. Designed for state-of-the-art performance and specifically to play Grados, the new RA1 will allow you to hear your headphones like never before. This new amp is machined from a solid block of mahogany and measures 5" wide, 5 1/2" deep and 1 1/2" tall and weighs in at 12 oz. The RA1 is available in an AC version or can be powered by two 9-Volt batteries that will drive the amp for 40 to 50 hours of listening pleasure. And the sound? Just like all Grados: warm, smooth, full-bodied, non-fatiguing and rich. Hook it up to any line source (portable or in-home) and drive your Grado headphones to their full potential. The Grado Labs RA1 headphone amp was designed specifically to drive Grado headphones and it does that quite decently indeed. It's recommended for use with fairly efficient (low impedance) headphones like the 32-Ohm Grado Labs headphone line. This is the battery-powered amp unit. The 'AC-power' Grado RA1 (Ac) version is also available. The RA1 design is small and fairly light for portable use, although that trad Grado wood-block design makes it somewhat bulky for easy travel and mobile listening on the fly. It's a very simple yet effective & the front panel sports a volume control, an on/off LED light, and a full-size 1/4" headphone jack. The rear of the amp provides an on/off switch and one pair of left/right RCA inputs. The battery compartment holds two 9V batteries, and is easily accessible via a metal plate with two screws located on the bottom of the amp. One bummer: the battery-powered Ra-1 does not operate with a wall wart/AC adapter.

 Schiit Audio Valhalla 2 Desktop Headphone Amplifier at 19743.00 PHP from TREOO.com
Schiit Audio Valhalla 2 Desktop Headphone Amplifier
₱ 19,743.00
TREOO.com
Go ahead. Do things with Valhalla 2 that you’d never attempt with other OTL tube amps. Run low-impedance headphones. Use IEMs. Valhalla 2 is a complete re-imagining of Valhalla, with improved performance, higher output capability, lower distortion and output impedance. Tubes Made Flexible While most tube OTL amps are really only designed for 300 ohm Senns and 600 ohm Beyers, Valhalla 2 stretches to include headphones that you’d never expect to use with a tube amp. Go ahead. Use it with Grados. Run it with AKGs. Rely on it for many IEMs. You may even like it with high-efficiency planars like Lcd-X, Lcd-Xc, Oppo Pm-1 and He-400. A Complete Desktop Preamp Valhalla 2 also adds two important features: preamp outs and a gain switch. Preamp outs let you connect your powered monitors directly to Valhalla 2, to give them some of what some people call “tube magic.” The gain switch gives you better control of both output level and impedance, for better matching to your headphones. It's easy to build a complete desktop system around the Valhalla. Not Your Father’s Tube Amp If you’re expecting syrupy, tubby, euphonically colored tube sound, you’re in for a shock. Valhalla 2 is exceptionally accurate, neutral, and resolving, without being strident or etched. Made in USA By “made in Usa;” we mean made in Usa. The vast majority of the total production cost of Asgard 2—chassis; boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley. 5-Year Warranty Asgard 2 is covered by a limited warranty that covers parts and labor for five years. That’s 5 years. Yes. Five. Which is up to 5X that of our competition, if you weren’t so hot at math. Note the marketing weasel-wording “up to.”

Teac Ha-501 Desktop Headphone Amplifier - Black
₱ 35,927.00
TREOO.com
Introduce yourself to TEAC’s Ha-501, a fully analog, dual monaural headphone amplifier with elegance. Part of the 501 series, this Class-A amplifier delivers superior sound quality, a sleek, modern look, all encased in a rugged but compact design. The Ha-501 supplies regular headphone listeners with quality sound, features and adaptable options that cannot be found in regular amplifiers. Pair it with your favorite headphones the same way you would a normal amp with favored speakers and take advantage of DC Servo Technology, Switchable damping Factors, High Output Power, a large Toroidal-Core Power Transformer and relax to your favorite music or radio broadcast. A headphone amplifier to achieve peak headphone performance In general, a headphone output from conventional hi-fi components does not allow even high-quality headphones to perform at their peak potential. The same way one chooses an amplifier to match with your favorite speakers, it is very impotant to chosse an appropriate headphone amplifier that matches your favorite headphones. A headphone amplifier is a "must-have" listening device for audiophiles. Active DC Servo Technology for decreased distortion, and discrete Class-A Amplifier In order to develop a first-class low distotion Class-A headphone amplifier, Teac held a series of sound evalutions during the development. These tests led to the careful choosing of parts and descrete circuit design. In addition, like most full-size hi-fi components, in order to eliminate Offset Electrical Potential, Active DC Servo Technology is utilized. Dual Monaural Design that eliminates interference between Left and Right channels In regards to the circuit design, each channel is completely designed on an individual basis to avoid signal interface to/from another. This contribution eliminates cross-talk, crucial headphone listening. Muses8920 Op-Amps - for high-end quality Muses8920 Op-Amp chip-sets are designed for high-end audio. Employed individually on the Left and Right channels, they help achieve superior sound. This Op-amp performs superb IV-conversion and is already very well regarded and used in a wide-range of hi-fi components. Large Toroidal-core Power Transformer An over-sized Toroidal-core power transformer is also employed to supply stable current to the every part of the circuit. Damping Factor Selector to optimize headphones' characteristic Each pair of headphones has its Damping Factor, a resisting force against non-intentional movement of the diaphram moving air forwards and backwords as sound. The value of the Damping Factor varies model by model, as diaphrams are made by different materials, in different shapes or different construction designs. Since headphones' diaphrams are activated by a very small current compared to conventional speakers, the damping factor increases, the sound is lean and crisp, and has a close relationship with headphones' impedance. Therefore, selecting the right Damping Factor is crucial in order for your headphones to perform at their peak potential. The Ha-501 provides 5 selectable Damping Factors, so users have the best suited signal for multiple headphones. Total 2,800mA of output power drives your high impedance headphones The Ha-501 schieves a remarkable 1,400mW output power per channel at 32 ohms impedance. The divice delivers not only enough power to drive standard headphones with an impedance range from 80 to 250 ohms, but also high-class 600 ohms hi-fi headphones. Robust Aluminum Body with a Classy Appearance Re-defining high class hi-fi components, the Ha-501 has a small footprint, classy appearance and is constructed with aluminum panels to create an authentic but modern looking hi-fi component. A robust metal construction helps eliminate vibrations that may affect the sound quality. The bottom and sidewalls are formed with a steel chassis, aluminum for the front panel and the rear panel out of steel. In order to ensure it's rugged design, each panel is connected with a beam that runs through the center of the unit. Normally, this type of construction is only for full-size components, particularly CD players that generate inherent motor vibrations. This construction ensures the Ha-501 is an authentic hi-fi component that will last you for many years. Choose between a handsome black version and a brilliant silver version to match with any interior or design. Well-designed User Interface Another remarkable feature of the Ha-501 is the user-friendly design. The firm-torqued volume control allows users to adjust the volume level with ease and precision while the toggle-type power switch assures On/off operation at a glance. Auto-muting function protects your ears from unexpected loud sounds when switching between headphones with different levels of impedance. Professional grade Input/Output connectors On the rear panel, a pair of Neutrik brand XLR input connectors allow users to connect high-end components or professional audio equipment, while wider-pitch RCA pin jacks allow user to connect large-shaft RCA pin cables from other markets. A detachale type 3-polar power inlet socket is also avalable. On the front, a 3.5mm stereo mini-jack allows users to connect a portable music player such as an iPod, conveniently. Switchable Output Mode for flexibility Line output level from the rear panel can be swiched amongst "Fixed Level", "Variable Level (coupled with volume)" and "Off".

₱ 7,516.00
TREOO.com
The Objective2 (O2) is an open source headphone amplifier designed by NwAvGuy, with emphasis on benchmark performance and low cost. This item includes a fully assembled and hand tested O2 amplifier, ready for use. You will only need an AC adapter suitable for your region. The O2 has created a stir in Head-Fi.org’s do-it-yourself community. After being banned from Head-Fi for heated discussion, he proceeded to design O2 for maximum benchmark performance to prove his points. It’s large and heavy, so hardly worth consideration as a portable amp, however, O2 lives up to its name. For more information on the O2, please refer to NwAvGuy's O2 Details article. Note: You need a separate power adapter with this device. If you do not have one, please add the G.e.z. 15Vac Power Adapter to cart. Customisation The default gain levels of the Objective2 are intended to work well with over 95% of headphones on the market. We use the stock O2 with headphones as low as 16 ohms @ 108 dB/mW, and as high as 600 ohms (very high and very low efficiency, respectively). There is no reason to change the stock gain unless you regularly listen at extremely low volumes. Gain can easily be changed by removing two resistors. You may choose for JDS Labs to set gain of 1.0x/6.5x or 2.5x/1.0x, and such customisations will only be on pre-order basis (2-3 weeks).

Background: The release of FiiO E12 (flagship of portable amplifier) was welcomed by the market. However, for some customers who are eagerly to try on something new, the original operational amplifier--OP AMP (Opa1611+Lme49600) still can’t make them satisfied. At present, FiiO Company is not in the right place to offer customized service, and different combination of the OP AMP can hardly help the customers to find the most favorite one through the objective sound feelings. Yet, in order to show our appreciation to those old customers and bring more fun in enjoying music, we specially invest effort in developing the DIY version based on E12. We are expecting to offer more options to our customers with this higher playability platform. Quantity: 2000pcs at its most worldwide. (The program would be terminated if the reservations run less than 500.) Target customers: The following requirements are not non-negotiable, but it is Strongly suggested for those who are ready to reserve to read each item carefully in order to avoid any unpleasant purchase experience. 1. Have certain operational ability; Since the customers are required to replace the OP AMP with the help of our manual, we don’t suggest average user to purchase in order to avoid burnout caused by faulty operation. 2. Old users of FiiO who know well of its products and service; Owing to the high cost of the high quality audio OP (the supplier has no stocks available), we can only move to production process after got the Full Payment of reservation. The production cycle would be pretty long, and for now we are unable to promise a definite delivery date. That’s why we don’t suggest users to buy this item when they had never bought any FiiO products before, since we are afraid they would cancel the reservation due to impatience or lack of trust. 3. Willing to accept the terms without after-sales service; For the DIY version, since it is practical to open the case to replace the OP by the end-user, we can hardly tell whether the issue is out of quality or man-made problem. In order to avoid unpredictable loss, we would seal the fixed screws before sending out, once found opened, we would not provide related after-sales service. Features of the E12 Diy: 1. On one hand, reserves the fine and meticulous workmanship of its commercial edition; on the other hand, offers more different timbre and fun with different OP combination. 2. Canceled the Bass and Crossfeed function, which offers larger space regarding the inner wiring layout, thus get its performance greatly improved. 3. Reserves the excellent high voltage power supply circuit of E12, ensure to make the most of its high quality audio OP. 4. Reserves all kinds of protection circuits and USB smart fast charging of E12. As to normal DIY amplifier, audiophiles would not pay much attention to this kind of design, and lack conditions to use the MCU to fulfill this function. 5. All the components are purchased from the first-class agent in China of companies like TI, Adi, which definitely prevent getting fake products in the purchase of DIY

Questyle Audio Cma800R Desktop Headphone Amplifier

TREOO.com
Hear your music for the first time! Questyle Audio’s outstanding "Current Mode Amplification" technology (subject to a PCT patent held by and the core technology designed and developed by, Questyle Audio CEO and founder Wang Fengshuo) provides the airiness and musicality of a tube amp while maintaining the speed and accuracy of transistors. What is Current Mode Amplification? In current mode amplification, the signal is amplified by modulating current instead of Voltage. It is widely applied in the high speed communication industry and the video processing industry, but it is Questyle Audio’s patented technology as applied to headphone amplifiers. Why We Choose Current Mode Amplification? Low distortion and wide bandwidth are the goals of all high performance amplifiers. Only with ultra wide bandwidth and high speed processing can an amplifier wonderfully process sudden pulse wave signals, and achieve realistic playback of music signal with speed and transparency. To achieve this Questyle Audio abandoned the traditional voltage mode format and developed “Current Mode” amplification. When the component is working in Current mode, the amplifier Slew Rate (Sr) achieves a linear increase as input signal amplitude increases, in direct proportion to the input signal amplitude. When receiving a high amplitude signal, a “Current Mode” amplifier’s SR is much faster than traditional Voltage mode devices, totally eliminating Timd and ensuring a high amplitude signal with an extremely wide linear bandwidth and an almost distortion free realistic playback. An Excellent Headphone Amplifier with Outstanding Performance Specifications 10mm Thick Aluminium Cover and Bottom Chassis The Questyle Audio CMA800R’s aluminum chassis is produced by Foxconn using precise CNC tooling machines. The upper cover and bottom chassis “mutual bit” structural design, provides the Questyle Audio Cma800R with stable heat, excellent control of sympathetic vibration and excellent shielding from Rfi/emi radiation. Mono Full Balanced Function The Questyle Audio Cma800R is the world first headphone amplifier to offer Mono Full Balanced output. To create a proper balanced output, a stereo amp is required for each channel. Rather than compromise by using a transformer or resistors, Questyle takes advantage of this by allowing you to switch two Questyle Audio CMA800Rs into “Mono” mode, putting each one into a “Mono Full Balanced” configuration, effectively bridging them in a “Duel Mono” set up. The output power is four times that of a single Questyle Audio Cma800R, separately driving the left and right channels, with an ultra-low 0.00038% distortion, and unparalleled channel separation, able to drive high impedance and low sensitivity headphones deeply, improving resolution and dynamics. In this Dual Mono configuration, each channel’s power supply and amplification are independent, providing first class driving power, which is especially outstanding in driving difficult to drive headphones or headphones which lack in sound field or separation.

Headphone Amplifiers Philippines

Amp up your Audio

Most mainstream headphones that are targeted towards the mainstream consumers come with many different sound qualities, and they often don’t require a lot of power to drive them. Just plug them into your computers or smartphones and you’ll be able to listen just fine. If you want to have some high-fidelity audio in your headphones however, they’re a whole different ballgame altogether.

High-end headphones are expensive, but they sound exceptionally good. While they delivery fantastic sound quality, expensive headphones tend to require a little bit more in terms of power; the typical computer and audio jacks on smartphones are usually not enough to power these headphones. That is where these headphone amplifiers come into play, giving these high-end headphones that much-required power boost.

The many different headphone amplifiers

Headphone amplifiers come in a variety of different shapes and sizes – as well as specifications and pricing. However, whenever people mention headphone amplifiers, it is commonly referring to portable amplifiers that can be taken around to be paired with digital audio players and smartphones. There are also desktop amplifiers that are made to power headphones at home, those are significantly larger and tend to require constant power supply rather than operate on a battery like most portable amplifiers do.

How to know if your headphones need an amplifier

There are several different ways to know if your headphones could do with the help of a headphone amplifier, and these are sometimes also conditional; some headphones may seem like they need an amp, but they don’t.

  • Your headphones sound quiet when plugged into your device, even at higher volumes.
  • Your headphones have a high impedance of 32 ohms or more.

Those two are the most common signs that your headphones could probably do with an amplifier. The issue with quiet headphones is more prevalent when it comes to mobile devices such as your music player or smartphone. The specifications of your headphone are also commonly listed on the back of the packaging where you will be able to see if it has a high impedance.

One thing to keep in mind that most in-ear headphones or earphones typically do not require the use of a headphone amplifier because they do not require much power. Most earphones are also optimized for use with mobile devices.

Great brands of headphone amplifiers in the Philippines

Like the headphones themselves, there are many different brands of headphone amplifiers, as well as different price points depending on the specifications and components in the amplifiers. Here are some great brands of headphone amplifiers:

Fiio

Fiio is a rather famous headphone amplifier brand – largely because of their excellent value. Most Fiio products aren’t expensive, but they deliver fantastic performance in comparison to the other brands out there.

AudioQuest

AudioQuest is famous for its DragonFly DAC/AMP that plugs directly into the USB ports of your computers. The DragonFly DAC/AMP gives your headphones the much needed power and also delivers cleaner and more detailed sound thanks to the built-in DAC.

Sony

Sony themselves are one of the pioneers of high-fidelity audio to mainstream consumers. They have a large line of music players as well as headphone amplifiers that may be a little on the expensive side of things, but deliver on all fronts.
