Thanks Charles, much appreciated. And you’re right that my preference, like yours apparently, is for tubes: I’ve been enthralled for the last ten years with a Shindo Giscours. But played through the Nenuphars, the Giscours imprinted the music too much for me. I believe a DHT pre, as Srajan claimed in his review of the SIT-1, is probably the way to go, although a reader posted on 6 Moons that he ordered a DHT from Thomas Mayer but was unhappy with its pairing with the SIT-1. I’m drawn to Vinnie Rossi’s latest DHT, but Srajan didn’t rave about it the way he did with the Trafomatic 10Y, which apparently was a one-off prototype. There are affordable DHT pre’s from Supratek and private builders like Radu Tarta, but scarce reviews make them seem like a shot in the dark.

I believe you owned--and maybe still do--the Coincident DHT pre--forget the name. Any impressions or feelings about compatibility you might relay?

riia,

You are right snd BTW I suspect I'd probably like the S.I.T.-1 even more than the highly praised S.I.T-3.

Coincident Statement line stage for over 10 years. I appreciate it more than ever. It's superb.

Steve,

Your comments concerning  the Shindo is in a sense surprising in regard to the level of perceived coloration/editorializing it imparted to your system. I do believe the Nenuphars unapologetically reveal all the is placed before them in the signal chain. So I feel that you heard the innate character of the Shindo Giscours as combined with your components and speakers.


I believe you would like the Coincident Statement Linestage (CSL) very much.  It utilizes a pair of the 101d DHT tubes and has transformer volume controls rather than one that is resistor based. Of its many attributes what stands out most IMO is the purity and transparency of its presentation. The natural tone/timbre/harmonics are rendered without gratuitous warmth or tint. Yet it’s the antithesis of clinical/threadbare/dry/analytical. The sense of flesh on the bone and living breathing performers is present.It has excellent dynamic capability and is very adept in revealing the nuances and subtleties of music reproduction.

You are very pleased with your Pass SP-22 and I can understand why. There’s no way I could say you’d be even happier with the CSL but I genuinely feel that you’d be pleased with it as well given your desire/preference of purity versus imposed sonic colorations. I suspect that the Vinnie Rossi DHT and the Trafomatic 10y DHT preamplifiers are excellent.

Charles,

Thanks for the insight into the CSL.  I do think it might be a great match for my system but I have one reservation: I have been spoiled by using a remote volume control.  I understand there was a version of the CSL made with a remote but that they had trouble with it.  Also, I've heard the MkII version has significant improvements over it's predecessor--I assume it was the MKII that came out briefly with a volume remote.  Any insights would be helpful.

Steve,

There was a remote version of the CSL a few years ago. Israel Blume did subsequently discontinued this version. The latest MK II CSL is further evolution and refinement of my original model and I'm sure even better. Given the level of satisfaction you have with the Pass SP 22 I'd imagine that you have very little incentive to replace it. It seems an ideal match with your S.I.T.-1.
