I must say I'm really impressed by this small power amplifier from 3e audio. It comes standard with OPA1656 op amps and not 1612 as the description says. No problem. The sound is very transparent and it gives enough gain to my Wharfedale Lintons. I have tested 5-6 different amplifiers with the TI TPA 3255, and this is the best implementation so far. Combine it with a Wiim Ultra and good medium priced neutral speakers. It's all you need. Sure my Purifi Eigentakt 2. gen. has much more gain to help with low volume mixed/mastered classical vinyl/CDs and streaming video with low volume and quality sound, but for everything else this 3e audio amplifier is all you'll ever need. It's a run and buy recommendation!
