Hmmmmm, not sure if this is going to be good advice or not, but I really liked the CJ PV series, and as I recall had a single series cap on the outputs.
Those contributed a lot to their sound, and upgrading them can be beneficial, but it has to be a labor of love as I don’t think you will recoup the cost. Perhaps a middle of the road approach is to use something like an Audyn TruCopper 0.1 bypass cap on each. Inexpensive, easy to reverse.
Thank you to those members who responded so far
To Erik Squires The PV14LS SE is the upgraded model which I purchased. The upgrades by the previous owner cost, at the time, about $500-$600.
BTW, I just purchased a used P.S.Audio Stellar S300 amp to use with the C.J. pre-amp. It has great dynamics and slam, but so far I am disappointed with imaging and soundstage. I don't know how many hours is on the amp. It was purchased from Music Direct via an Audiogon sale ad
I previously posted two threads on AG asking about Schiit Vidar amp, but received no replies. The second thread asked about the Nuprime ST-10 and the Channel Island C100 amp and also the CS200C ( which I would have preferred)), but received no feedback Choices were based on size and performance. I'll have to wait to see if I warm to the Stellar 300S
The S-300 needs to be left powered on all the time to achieve optimal performance from it. Still even under those conditions that thin somewhat edgy sound is typical from the the generation of ICE modules used in that amp as they are from quite a while ago. I owned a pair of W4S mAmps with modules from the same generation and they sounded similar to what you describe. Never heard Dusty's Channel Island amps but I do own a Nuprime ST-10 and it sounds nothing like the S-300. Much more refined amp in every way. For a SS preamp that meets your stated requirements look at the Van Alstine Vision SLR.
Thank you for the reply; I seriously considered the NuPrime ST-10 and actually put a "wanted" ad on U.S.Audio Mart, but received no replies I also checked Audiogon almost every day for one...No dice. So after months with music, I decided to buy the S-300.
I may inquire with .on-line dealers about a trade-in toward an ST-10. To its credit,, the S-300 has great dynamics and tight bass; but, the sound gets less somewhat tangled with less resolution, and as I said before, becomes edgy Fortunately, I got a good deal on the S-300 which though used looks mint.
