Final update, 18 months after purchase: I just gotta pop back in and say, this amp is an amazing deal now. They slapped an off-the-shelf class-D amp module into a plastic box, along with presumably compotent but mediocre components, and deliver audiophile sound on a beer budget. The price seems to have stabilized, at least for the silver unit, at way under four hundred bucks (I paid much more when it first came out).I've recently auditioned some really amazing speakers with it, and the Teac did the speakers proud.

One issue much discussed with Class-D amps is the potential for under-powering speakers, which could theoretically burn them out by delivering clipped square waves from the little amp if pushed too far. In real-life, it's not an issue unless you enjoy shaking the floor/windows. The Teac's 22wpc into 8 ohms seems small, but I put a sound pressure level meter on myself and it turns out my comfortable cranked-up listening level, about 10 feet from the speakers, is about 80-82dB. Doing all the math, FWIW, that translates on my speakers to less than 2 watts of juice, plus more than enough dynamic headroom to very safely avoid clipping. The manual says speakers should be 87dB or higher, which I agree with in that you can get to pretty extreme loudness (93 dB or so) 10 feet from the speakers in a typically-furnished room without potentially clipping the amp: lower the volume to a level where you can talk over it to someone right beside you without raising your voice, and even below-average sensitivity speakers will be far from pushing the envelope.

For a medium-sized room, 87dB (e.g.

I'm going to keep this review concise

Description: the Teac AH01 is an compact desktop amp with DAC that is an ideal central hub for a compact or desktop stereo system.

- Compact size. Only 8.5 wide and deep, which is a lot smaller than many other conventional integrated amps of this quality.
- Runs cool. The digital amp doesn't put out a lot of heat when working hard due to the efficiencies of its digital amp.
- Uses the proven B&O ICEpower 25W module. This 50ASX2SE module is a solid performer (you can google its specs). The important thing to note is that it maintains a very flat frequency response (20-20K hz) with even low impedance speakers and maintains a low distortion for accurate sound.
- It has a decent 25W of power into 8 ohms but offers 50W of power into 4 ohm speakers. This is ideal (technically it's a "constant voltage source"). So it provides the necessary current to drive a wide range of speakers without prematurely running out of steam. It should be able to drive a small to medium size bookshelf speaker in a bedroom or desktop system with room filling volume.
- Inputs: It provides a wide selection of digital inputs for any of your digital stereo components. You can use this as your computer's soundcard with its high quality asynchronous USB input. Or attach it to your CD player. If you have an iDevice, you'll want to add the companion DS-H01 dock.
- The DAC is a Burr-Brown PCM5102 which can decode your 32bit/192kHz digital streams to handle your audiophile grade media files.
- No power brick! Usually many little amps have a large external power adapter but this one has a power cord that goes directly into the back of the unit.

I feel like to update my experience as an end user. I replaced mine and eventually returned the replaced one due to product deficit. It sounds well when it works. However it constantly shows blue screen in windows 7, in my laptop and in my desktop. I emailed TEAC customer support and waited for about 3 weeks. No response. I googled and figured out that other uses have reported the same problem but TEAC failed to resolve it. From other reviews, other users seem to have pretty got experience of this product. But it just was for me. In brief, I don't recommend this product.

I have been looking for a good amplifier to drive my headphones. After visiting quite a bit websites I landed myself with this Teac AH-01 due to its support of a wide variety and its affordable price. Setup is easy and quick. Simply install the Windows driver download from Teac website, plug in power cords and hook up USB cables then you're good to go. Everything sounds too good to be true, doesn't it? Yes, it does.

At first I experienced a noticeable background buzzing sound. I simply cannot stand for it at a quite night. I tried to figure out what its root cause is so I use an independent power plug, switch to different USB ports of my desktop, switch to USB port of my laptop, change USB cables, switch to use s/pdif connection from my desktop, use different fooboar plug-in (including DirectSound and WASAPI), tried the Teac-made music player from their website...etc. None of these works. The buzzing sound is like a ghost that show up in the gap between every played songs.

Eventually I decided to ask for a replacement from Amazon and ... it works.

The other issue I encountered is the stability of its USB driver.
