What can you tell me about First Sound pre-amps?

I misplaced the acronyms, referring to FS in the first instance, as in strong dynamics, stark, clear sound.

I suppose it depends on taste at higher levels, but the CAT jumped out in front in terms of musicality and rightness, immediately inviting, vibrant and silky smooth but not at the expense of anything else that comes to mind. FS on the other hand, had some strong attributes, but was not strikingly musical, beautiful or involving, IMO, as someone who goes with first impressions and then confirms them..

Analogbass - which incarnation of the CAT were you comparing to which FS preamp?

What are you going to replace your CAT with? Just curious. Though maybe you might climb the FS ladder. Hope you are well. :-)

Oldpert, still havent decided, but i did finally decide to put the PW6922's up for sale, which signals it probably wont be a FS since the FS was amazing with that particular tube...

Art, what happened to you system thread? It seems to have dematerialized. Did you compare the CAT with the Callisto last weekend?
