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 would strongly suggest that you audition such an amp with your speakers, as they sound very different from the Class A bias amps that you have so far seemed to have a preference for. Not that they sound bad like some older Class D designs, just that they're different than Class A.
That is good advice Bill K.

I owned the M300s for several years and sold them last year. I currently own the Atsah NC1200 monos and a very tricked out McCormack/SMc DNA-2 LAE. So, I have had Class A, Class D and very good Class A/B amps all within a year. They are all very close in power ratings and not far separated in price. I still can't decide whether to keep the Class D monos or the Class A/B amp.

If I still owned the M300s the only thing that would change is that I wouldn't be able to decide between three amps, instead of between two amps. All of these are excellent sounding amplifiers, near the top of their class, and I suspect I would be happy with any of them but, they do sound different from each other. Listening with your own speakers is a really good idea to be sure of what you are getting.
"What do you guys think about the guy that builds the Hypex Ncore amps James Romeyn.

They seem like a great deal and are pretty much the same as the $4800 Thor from Merrill just without the fancy case."

No they are NOT the same. Different modules.
I have no dog in this fight, but even if they share some common parts other elements are usually different. For instance capacitors vary widely with regard to SQ and which resistors you use, and the ratings of those components can differ. They may look a lot alike but be quite different. That is giving them the benefit of the doubt.
Arguing for the same except for the casework is the generally accepted knowledge that the case work in general and faceplates in particulars are frequently the most expensive element in an amp.
There's no free lunch. Tubes and solid state will never sound the same.

Class D has gotten so much better, but in my opinion suffers from sort of a one-note bottom (some are better than others). Plenty of bass in Class D but not as much articulation and differentiation as from better solid state.

I am enjoying a Devialet D400, a hybrid Class A and Class D design. My D400 can not take place of my CJ GAT/ART monos, but it's a nice change and runs cooler for the peak summer months.

I often enjoy a tube preamp and SS amp or the opposite too. Tubes give the that tremendous 3D, depth, width, bloom, sweetness and air that no solid state can give you. On the other hand, SS give you that tight fisted control over bass and no tube worry.

My Devialet D400 as a dac/preamp into my CJ amps sounds amazing too. It's great to have options to help you appreciate what gear you truly love.

I love my Class A (Pass XA60.5's) on my SF Strads and Harbeth 40.1's, especially with my GAT tube preamp.

Nothing is perfect, I love and look for a great treble and midrange. I'll give up a little on the bass to get that musicality that I love.
