I thought I recalled reading that the designers of the Custom 225 incorporated some sonic qualities of the Sunn 2000S into the amplifier.
Speaking of which, has anyone heard or tested the C4 preamp designed and sold by the Sunn Godfather?

I posted a long dissertation on the Reeves C225 in
July 2007 in which I used 2000Ss as a frame of reference, but as far as I know the C225 was based on the AP Hiwatt DR201 and tweaked to be more bass guitar specific; mostly more bottom end and power/headroom. The prototype I tested was actually built on a British DR201 chassis, with Reeves spec built Heyboer iron and Reeves stuffed turret boards. The reason I used the Sunn 2000S for comparison is twofold; Im a huge fan of the big Sunns, and also they were the only 4 X KT88 amps I had on hand for comparison.
A healthy 2000S rig is a very tasty rig indeed; a dinosaur, cumbersome, heavy and lacking in features, but big, rich, clean, very touch responsive and just well
Tasty.
A fact that wasnt lost on the Reeves guys during my C225 test sessions based on their comments when I had the big Sunns cooking.
We spent a lot of time with the 2000Ss, and it was
before the C225 was finalized, so I cant discount the possibility that the final tone tweaks were at least in part inspired by the big Sunns. However, the Hiwatt was the base inspiration for the Custom 225 IMO.
Id love to check out Mr. Sundholms C4 preamp, Ive never
heard it but its pedigree is outstanding.
I recall reading that some Sunn tube amps had complete Dynaco hi-fi amps under the hood of their products, not that there's anything wrong with that. If it works, it works.
The earliest Sunns were Dynaco Mk III and Mk IV amplifiers and a modified Dynaco PAM 1 mono preamp mounted in a box in a split chassis amp configuration. As they progressed they became the more familiar single chassis Sunns that most of us are familiar with, and strayed some from the Dynaco design but still kept the basic circuit intact.
But
There are plenty of Sunn threads here, this one is The Official
REEVES Bass Amp Thread, so Im feeling a little guilty about the hijack.
