Clayton Audio Class A amps. Need amp advice


Hi Guys,

I am looking to change my amps and for a few reasons.

First because I just upgraded my DAC from the great PS Audio DirectStream to the incredible Bricasti M1 DSD USB DAC. I love the Bricasti and it has shown that in my system it could offer me more with a more resolving and neutral amp IMO.

I am currently am using the wonderful sounding CJ Premier 12 mono tube amps. I love them and tubes in general but my speakers are the great Ascendo C8 Renaissance and look to present a somewhat benign load being 88 efficient and 6ohm but they are unique and have an internal firing 21 cm Kevlar Bass driver that is great but stubborn and the speakers I think will really shine with a iron fist control of that driver.

I love tubes, always have and always will but I grown tires of a flabby bottom which is exasperated by a unique and somewhat difficult to grip bass driver set up I spoke about above.

I want an amp that can give me as much tube sound as possible but with Grip and bottom end. I know this is a lot to ask for in the used $5k to $7k price range.

I have read and it seem like the Clayton offer exactly what I am looking for but wanted to hear from some of you guys if anyone has ever heard them or know of them or anything. Any info would really be appreciated. Here is the info on my speakers and I will also list the rest of my system in case you think that is helpful. Thanks

I loved the S40 and would have bought it but after listening after a couple days a channel went out. Kind of stinks because the amp was just back from the factory and had full rebuilt and improved special power supply at the factory with the same power supply of the 200 and it was great. It was sweet like a tube amp, also a bit dark but I liked it a lot and was a happy camper with it. I went down during a few day audition and i never heard back from the dealer. It may still be out getting fixed he said he will me when it gets back. The Krell was a couple towns away so I wanted to try it. Love to try local stuff when I can because so rare. oh I like the S40 better but it couldn't grab the drivers like that freek Krell. That said overall the S40 is more refined and more up my alley. If this Krell was a little less dark and had more of the refinement of the S40 that would be my best amp. I still prefer tubes no doubt but with the kind of speakers I am using to get this type of tube performance its very expensive.

I would love to try the Merrill Audio class d amps. They use that new amazing modular Hypecore thing class d that is supposed to the best new tech in all of audio for amps. Expensive though also. Trying to stay in that $3kish used price range for now. I am def making a speaker change. I love my speaker but to properly drive them I need the type of amp that I don'y love or have grown tired of trying.
So it sounds as if the Clayton M300's are for you then. They will have more bass slam, like that Krell, plus the refinement of the Clayton.
From my recollection of that vintage KSA, they were Class A amps? Yes, a bit dark in some respects like my former Gryphon Antileon (also pure Class A, 100 watts), which is probably similar vintage. But where i found the older Krells relative to other amps i have since heard is that i felt there seemed to be [a bit] of grain.

But yes, I agree, the KSA 50, KSA200 were not from what i recall tinny, bright, cold amps at all. Things did change as time went on, but not that particular generation.
The model of the Krell mentioned, the 200s, was one of the first of Krell's amps that had a "sustained plateau" bias--definitely not a class A amp. It was not the class A KSA 200, which was two models before that (and a much better-sounding amplifier, IMHO).
