After 20 years, in the market for a power amp

Second hand Vitus SS101 and vayas con Dios.

I love my Odyssey Kismet Extreme Monoblocks and hope they last a long time. Odyssey has a sound you might miss, could be worth a call over to Klaus and discuss your issues and needs and maybe he could get you back on track. 
There’s nothing out there at his quality level for the price and he takes care of his customers…

I agree with audiophile1.  Over the last 20 years I have paired tubed preamps with Bryston SS power amps. Bryston amps are neutral, powerful, effortless and dependable. Currently I use the Bryston 14b3, but the Bryston 4b3 is a real solid piece of gear and can be found used for 3500 to 4000 range. Since the Bryston is so neutral, your sound will be determined by what your tube preamp (and cable choices) sound like.  

+1 on the CODA S5.5, best SS Class A amp the near side of $6K new IMHO, but might not work well with your tube pre unless it has low-ish impedance.

Make sure whatever you are looking at matches up well in terms of impedance.

I would call Doug Dale with Coda.  Tell him what you have for gear.  You should also think about your long term plan.  Will you ever change speakers?

For my Von Schweikert Endeavor RE speakers, Doug recommended the No 8, V1.  That's what I bought.

I've been using tube preamps with solid state amps for years.  First were conrad-johnson.  Now it's a Linear Tube Audio MicroZOTL preamp.
