What's Best Audio and Video Forum. The Best High End Audio Forum on the planet!

INTRODUCTION:
Thought I would share a few initial impressions of Joel Durand's latest and greatest effort: The Tosca. First a couple of caveats: Joel and I are personal friends and I served as one of Joel's "sounding boards" during development; so there is an implicit positive bias. That is balanced by my innate thriftiness (OK, I'm cheap) and reluctance to make changes in my system...

One can see from the three photographs below how the extra weights change the size of the counterweight, lower its center of gravity, and alters its position relative to the arm's pivot point.

I have had the Nagra HD with PSU now for a long time and was very pleased with it. Fantastic sound both with C.E.C TLO 3.0 transport and with
computer Mac pro laptop with AUDIONIRVA plus and my 3000cd collection on NAS. TIDAL is very good and even Spotify played via Aragon spotify box on the Nagra sound very good.
I now got the new Nagra Tube Dac w new Classic PSU. A considerable economic...
