Summary: I honestly just don't get all these huge amps anymore. this amp is super clear and simple--unless you're running some big surround sound system in multiple rooms, there's no need for anything more. this will run any pair of speakers extremely well. Solid for the money too.
Summary: I bought this for use with a television that has horrible built in speakers and was very pleased from the moment it started palying. This amp consumes very little power and barely gets warm to the touch. Using the optical input from the tv and analog inputs from two other devices and the sound is perfect. USB input also works perfectly. I connected some very good speakers and played music from a cd player and computer.
Above average performance with some minor hiccups and USB driver problem

Summary: [Update] 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.
Summary: I wanted something compact and digital music compatible, and the specs seemed right on this one. I'm running Magnapan MMGWs, which seemed a good match at 5 ohms and 88 db sensitivity, with AppleTV and an iPod deck for my music sources. Plenty loud for my listening (classical, jazz, folk mainly). I rarely go past about 2 o'clock on the volume dial.
Summary: The first unit I received did not turn on at all. Amazon sent a replacement amazingly fast, so credit to them. The second unit turned on ok, but did not install on my laptop. I should say it installed, but then as soon as any sound was run through it, it disappeared. I already had installed the drivers there. By the way the URL in the instructions was out of date. I was able to find it, but I imagine this could be very frustrating for some people.
Summary: I bought this to drive my office sound system (Cambridge soundworks speakers, velodyne powered subwoofer). The major appeals were the small footprint and energy efficiency. I use an iMac which I connect to the Teac AH01-S by a USB and analog connection. Both work as does the optical connection from the iMac's headphone jack. The only reason to use the analog connector is that some notification dings don't seem to work through the USB connection. This is an excellent amp.
Summary: I bought this unit as a replacement for a smaller T-Amp that wasn't delivering the power I needed. I have a small set-up with a Grace WiFi tuner and Luxman Turntable. I wanted to get a quality sound out of the tuner using the coaxial output and also be able to run my turntable and get a decent sound. I didn't need anything earth shaking. This unit is very reliable, very easy to use and configure and has great sound quality. I've been thoroughly impressed.
