Ha Ha. There is really nothing to upgrade except possibly my speakers and the only two real candidates are out of my comfort zone.

Comfort is overrated!

Jim and Steve,
I had the upgraded tone board put in last Saturday, attached are a couple of pictures. The tone board is the smaller board on the right. Visually the only difference appears to be slightly larger caps in the new one. Sonically, the difference is subtle: I did notice a slight improvement in bass definition and oomph. I picked up new cables the same day but made sure to listen for a few hours to the new board before swapping cables.

One warning, there’s a glitch in my new board - when I engage the tone controls, the right channel drops considerably, almost muting. I tried all the tricks: re-pairing the remote, resetting the balance, holding the balance button for 10 seconds, etc., but it appears to be a problem with the board - maybe just mine, but don’t know that yet. I called my dealer on Saturday evening and am still waiting to hear back. I’m not out of commission, since I don’t use the tone controls very often, but it will be a pain if I have to pull it back out of the rack and drive to Seattle again.

I "thought" that the tone update did not relate to the tone controls. I must be wrong. If it only impacts those controls I might pass on the update. Like you I have hardly ever touched them. The times I want to boost the mid-bass region I have just used Roon.

Keep us posted.

According to the dealer, it doesn’t just affect the tone controls, but I may have misunderstood.

Thank you for the update, Tony. Maybe I’m not in such a hurry after all, if there is a glitch in the board. Do keep us posted.

PS: I didn’t see any pictures attached.

Latest update: just heard from the dealer, D’Agostino has been able to reproduce my problem, it’s a chip in my board that’s defective - other boards are fine, so they’re shipping a new board to Seattle to replace mine.

FYI, the upgraded board does impact overall performance, not just the tone control circuits.

Thanks very much, Tony. I appreciate the update and additional information.

Still waiting to hear back when I can bring mine in.
