Coincident Linestage vs CJ CT5 or Allnic L-3000

Jordan,
I seconded the idea to call Israel, this is a strange problem as silence is a strength of the CSL. Pap says the CSL was dead quiet with his Soulution 710 amplifier ((just to mentioned another example of a SS ammp match). Maybe it's the Valvet that "could" be uniquely incompatible with the CSL. Did you have any problems when connected to the Frankenstein? I think this is a solvable issue.
Charles,

Jordan, You have superb equipment, and zero noise should be the expectation. If I were starting from scratch, knowing what I know now, I'd put together an all coincident system paired with my modwright sony (or an oppo) and be done. But I'm not starting from scratch, and I'm not kicking my Maggies to the curb, so the goal (and part of the fun) is making everything I have sing in harmony. Sadly, I really can't drive my Maggies with Franks.

Please let us know what sort of help Israel can offer on this. His customer base for the CSL really should explode, but he has to effectively serve the mix and match market to make that happen.

Charles - it is/was present with the Franks, Atma's, and Audions, though amplifier gain affected the ratio of signal to noise and hence how obtrustive it was. With the Audions I can eliminate it with low gain.

I am not certain that the CSL is the cause or contributor. It does not increase or decrease with CSL volume pot position, only power amp gain. Following the Jensen trouble-shooting guide, I'm left with:

the noise is coupling into to the cable by induction. This is most often caused by a
strong magnetic field near the cable. Such magnetic fields are produced by power wiring,
power transformers, and TV or computer CRT displays. Electrostatic coupling is also
possible, but rare in a cable which has a grounded outer shield. Route all signal cables to
avoid such strong fields.

In response to this discovery last year, I first tried a different cable (no difference), then I tried routing the cables completely away from any power cords or transformers...still no improvement. The only power line close to the cable is the PS cable for the CSL and that's DC. I eventually just lowered the gain on the Audions.

Jordan,
I agree with you and find it hard to believe it is the CSL as the root problem . Did this occur with the CF preamp in your system?

Did this occur with the CF preamp in your system?

Yes it did, Charles. So this leaves me with these facts which don't make much sense: 1.) DAC to amps direct via balanced or SE -> no noise. 2.) DAC to Linestage to amp via balanced or SE -> noise. Since I've tried a few different wiring schemes and isolation transformers between Linestage and amps, I'm not really sure what else to try?
