I bought this recently and highly recommend it to anyone who is interested in setting up a high performance (but moderately priced) home theatre system.
I hooked this up to my video player which has an optical Toslink output for the sound.
The speakers I am using are Alesis Monitor 1 MK2 passive speakers (which is btw, another highly rated giant killer).
As long as you are pairing this amp with efficient speakers, you will experience very good results.
I have not had to turn up the volume on the T2 amp to more than the 1/3 mark clockwise from zero volume.
Using the stock Chinese tubes, I watched the movie "Zathura: A Space Adventure".
There was this scene from the movie whereby there was a stream of water on the right side of the screen when the protaganist was escaping from some lizard man-eating aliens.
With this T2 amp, I actually heard the water stream flowing from top to bottom on my right!
This was exactly what was shown during the movie.
So for an outlay of around US$1000 ($795 T2 amp + Flat worldwide Shipping $40 + Speakers $200), you can get 3D surround sound from a 2 channel speaker setup.
This is really neat! :)
My T2 amp is still undergoing the burn-in stage(*) at the moment and I'll post a more comprehensive review soon.
(*) About 10hrs so far out of the manufacturer recommended 50hrs.
This is not inclusive of the 24hr burn-in time after I upgraded and replaced all the stock Chinese tubes with various 1950s NOS tubes I purchased from other tube suppliers.
