Should I trade up from a Kavent/Shengya/Vincent mono block ??

Re. Ps Audio Stellar... Respectfully totally disagree... Got one to hold me over until my tube amp got fixed... and was shocked at how good it it sounds.  I was especially surprised being that it was a class d amp... I'd been disappointed by them in the past. 

May be due to to synergy in my system... But one of the best amps I have ever owned. 

As a bonus PS Audio is a great and supportive company. 

See I was right ;) ... Sorry was prompted by the original.. Belated reply. 

I’ve got the 300 and love it...

Happy Listening Pauly!
