Plinius amp and Conrad-Johnson 16LS


I'm thinking about changing my system back to Plinius SA-100 amps (mono blocks) and maybe using a Conrad-Johnson 16LS pre-amp. Has anyone had any experience with these two together? The Plinius I'm trying right now has such great pace and slam but is lacking in the final warmth a tube pre-amp might add. The Aloia gear I've been using is all equal to the Plinius just not as much of everything. The warmth and lack of electronic sound of the Aloia is more pleasing to my ear, if I could have both...

Hi JD

Remember those Plinius amps need 3 months of decent use to come right. You will also find the SA102 to be warmer and more liquid than the SA100 MkIII. I doubt that a tube preamp is the way to go since you will lose the pacing of the Plinius (will get me some reactions to that one, I'm sure).

Contrary to what Peter Thompson says (Mr Plinius) I find the Cardas Neutral Reference, or Cardas Golden Reference are great with the Plinius (Peter recommends Siltech - but hey, he also listens to Shahinians).

Plinius uses a very hard footer that can dry things out a bit. I keep recommending them - so maybe I should buy some shares - but the E-A-R feet are what I use under my Plinius.

I sincerely hope you are well JD. Sorry about being out of touch for so long.
I like the Placette buffered preamp - has none of the hard grain of most moderately priced ss preamps, and has the pacing that is so hard to find in valve preamps. Can be had on a money back trial - but its construction is tenuous. My advice is don't open it and you will never know. The E-A-R feet will only handle about 10 to 20 lbs comfortably each. Six or eight of them ought to be right for the SA102. The Walkers are very good, but with less warmth that the E-A-R feet. In fact the E-A-R are just a finishing touch - the key issue is those Neuance shelves (or something similar) - I have not tried Ken's new version for heavier components.

By the way JD - are you using the SA102s bridged, or bi-amping? There are downsides to using Plinius amps in balanced or bridged modes.
JD, the Placette has a very clean grainless mid that, if it has a coloration, it is an added sparkle - a slight golden glow.

The SA102 sounds much more like the SA250 than the SA100 III did - ie more liquid (less dry - whatever) and fuller, plus better extension at the extremes.

The balanced on the Plinius amps that I have taken apart, is not balanced at all. That is, the amp is not balanced - just the input. They use an IC (yuck) to handle the inversion, meaning when you use balanced you get the sound of an additional stage - that is executed by using a simple IC. You could probably deduce from this that Plinius believe in single-ended (RCA) and do not believe that making the amp fully balanced is worth it - and I would agree with them. Just don't waste your money on balanced interconnects. Listening to a Plinius amp and comparing RCA with balanced will prove this to you - more grit with balanced.

I am pretty sure the bridging involves the use of ICs on the input side too, but cannot say for certain.
