SMSL amps seem to be fairly well regarded.
I got the same advice from someone else, also I got the advice to invest in a Rotel RB 980 RB, although theye are more likely to cost ~300€.
Regarding the SMSL, they are when I get that correctly, all class-D amps.
I don't know much about amps, but aren't class-D amps kinda the stuff you try to avoid, because those are the "cheap but efficient" electric stuff that just don't deliver the sound you want when going for a decent stereo amp?
I don't think I'm anywhere near a price range, where I can get a decent tube amp, but maybe I should just get one of those SMSLs and check if it suits my needs before investing triple of that price.
Then in a couple of years buy something decent when I finally/hopefully have the money.
The NAD seems good though and is a good starting point to compare, so thanks already.
