Solid state amp around 2000-2500 used or new

Why, a pair of DIY Hypex NCore NC400 monoblocks of course.

schubert: which Odyssey amp did you have? Also is the synergy 550 discontinued, I couldn't find it on the site?

Sorry, my amp is a 450, there is no 550, my minds going. in any event its doing a great job right now letting me hear all all the lines and instruments in Brahms 3rd, something neither my Odyssety Khartago or Stratos could, sweet as they were.

I would go for a XA30.5. Even for a 30watt class A it is a lot better than the 150.5. Musical fidelity is an almost 2 dimensional sound. I did shows for MF in the past and I owned the best stuff they have. Pass labs is superior in 3d imaging compared to MF. I had the 150.5 for some time to test. I was not convinced. XA30.5 is so much better. And control is quite good. 150.5 does not have more control. As you would expect!!

You can't beat Class A!
