Coincident Linestage vs CJ CT5 or Allnic L-3000

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?

Th sonly time I have encountered any noise was with the CSLS partnered with Halcro power amps AND with the mute switch on. The owner of the Halcro contacted Israel who i understand was aware of this on happening on rare occasions and has made changes to newer models. It was no big deal for me because it was totally silent with the mute "off" mso it wouldn't be a problem using it.

Apart from the Soulutiion 710, have also hooked up the CSLS to a pair of Gryphon Colosseum monoblocks, Jungson JA-100's , Bakoon amps, Doge 9's, mingda and McCormack power amps and one or two others with absolute silence at all times and being fed by DAC's CD players and phono stages.

I think Brownsfan's advice is right on the money - its worth talking to Israel to help solve the problem although new owners shouldn't have this issue in future.
