-Very good turntable system indeed, the Spacedeck. Is the arm a current Helius?

-Interesting and many diy experiments I see in your photo link. Bravo.
Why is the AGV for? Don't tell me that you ride an Italian Desmo with a dry clutch...goes well with no feedback and full range attitude.

...Don't drag me in to speakers, its going to be OT hell!

Because speakers are my love and specialty...

OK, just a little OT... You very well love OB detail and space and freedom for 2 reasons mainly: 1st critical msec of reproduction is free from box congestion, figure of 8 pattern is a means of controlled dispersion, i.e. less room coloration.

...Back to Salas RIAA.

After checking the Steve Bench cascode diy tube unit for preferred matched tubes, best stabilized PSU, best step up choice (gutted the Dyna DV6Z and put it inside the Bench so to avoid RCAs and cables), fine tuned its riaa eq etc. and did some comparisons with the Salas, I can confidently say that the only difference is the JFET characteristic VS the tube one. Just some less interest in music interplay, and a somewhat tamer tone. Of course if you weigh in the time, effort, and money to make the Bench or the Salas, and also the expertize needed not to screw the Bench... The 5-10% specific area difference is up to personal taste. In general, they are in same class for transparency, projection, and sheer musicality.

Silver/Oil I use. Its a matter of a combination of things. In my assortment of parts and circuit decisions, PSU etc, it works balanced. But yes, if the circuit and parts or MC & speakers tend to be higher midrange projecting, an S/O will not help. A Jensen Copper Foil would do better in such a case.
