After 20 years, in the market for a power amp

Fair question. But after 20 years, I’m ready for something else. I’m a huge Klaus Bunge fan, and I’m going to be sending the Khartago in for repair and to serve as a backup amp. (I gave my old backup away) But I’m not specifically opposed to going back to Odyssey, (and have considered going to Stratos monoblocks, but I lack adequate space for them)

nice budget. My "pricey" list would be Sugden, Simaudio, Hegel, Moonriver

A couple of years ago I found a used Ayre VX5-Twenty and it is such a great match with all the different speakers I’ve used with it—Maggie 1.7i, Audio Physic Avantera+, ProAc, Genesis 7f. A very versatile and reliable amp for the long haul. 

I know there are strong opinions about class D amps and if you have a strong bias against them, I might as well shut up right now :). However if you don’t, there are a number of class D offerings featuring Hypex and Purifi modules as well as ICEpower amps by OEM manufacturers. While many will poo-poo their sonic signature or perhaps the lack thereof, class D has truly arrived. Their advantages over other more traditional architecture is well documented and quite valid. I just recently got a VTV amplifier (assembled in Ohio) featuring the Hypex NC502 module that is one of the cleanest I have ever heard. Neutral, powerful, cool running and 350-ish clean watts into 6 ohms. Physically attractive in a minimalist kind of way and 759 bucks delivered. Hard to argue with roughly $1/watt of quality amplification. This could save you a ton of money over some choices you could make and you get a 30 day trial period. If you don’t like it send it back for a refund. Warren was great to deal with and answered my questions prior to purchase. No, I am not being compensated for the recommendation. Its based entirely on my own satisfaction with what I got for my money.

@livinon2wheels Well I believe I am qualified to comment on this. I have owned Nord NC500's, a VTV NC500 and I still own IMO the best quality Hypex amp one can buy: an Apollon NCx500. I agree, they are clean, neutral, powerful, have wonderful clarity and detail, tight bass.

And then I heard a class A Coda. No comparison. 

No bias, no judgements, no ignorance, just facts. The Apollon is a wonderful $2000 amplifier that with quality cabling probably out performs most amplifiers under $4000. But if one's budget is 5-7K and one can get a Coda (or similar) don't even consider Hypex. IMO. 

OP: Strange you mentioned maggies, I also have a Primaluna Pre, and Maggies, and like you felt like doing something different, so just picked up another set of speakers, and have some other tube amps coming.

If you are looking at Pass Labs amplifiers, (as many people do) maybe you could ask @audphile1 to add more details regarding his extensive experiences with them compared to Coda and what he has now. 

Your comment above comes across as a little odd, in that you seem to be leaning towards building your system around your Primaluna pre?- correct me if I am wrong. Having said that I am sure it wouldn't be the first time- I think most people build a system around a set of speakers, but maybe just as many love an amp and they get speakers and other components to match? I don't know- just thinking out loud. Then typically the last piece of the puzzle is the cabling to add that last bit of spice into their "meal". Lots of ways to enjoy this hobby and get better sound!

Have you already played with NOS tubes in your Primaluna? It was a HUGE difference for me. 

Pathos makes a great sounding amp...
