I had heard a lot of raving over this amp in some audiophile forums, and ended up getting one for my studio monitors. I was honestly blown away by what an improvement this is over my old T.Amp. No noise can be heard at all, its dead quiet, and I have somewhat sensitive speakers at 90db@1m/1W.
There is no annoying "auto shutdown" that messes with it during low-volume listening, and the overall audio quality is remarkable.
I cant say how it performs in the low-end since I use an active sub with my setup, but they do a wonderfull job at driving my studio monitors, which are quite power hungry Snake monitors.
It is worth mentioning that this unit does get a bit hot, and should be placed very "airy", you cant stack anything on top of it really. It seems to stay the same warm temerature regardless of volume actually used.
In the end, this is an amazing amp at a crazy low price point.
You'll have to spend a looooot more than this to get this level of performance from another passive amp, thats for sure.
