Interesting thread. I'm coming in pretty late. I've seen this before and it seems like the OP is looking for support for his choices. Opinions were given regarding potential QC issues of a Chinese made product at a very low price point which is valid. Also, he mentions not needing a lot of power which is true except when the dynamics of the music call for more. Then the system will sound weak. In this price range I'd look for SS amplification. There are far more choices with proven suppliers.
Inexpensive Tube Amps
Anyone have any experience with the following? I want to try one just to see how the sound compares to my Yamaha and Denon solid states. Since the Denon is living on borrowed time I will likely have to replace it this year anyway. Looking at the Nubsound and noted a Germtune that is identical to the Nubsound but costs a bit more. Reviews are largely good including those on other forums.
