I use Franks UltraValve with them, used to use an Onkyo SR805 AVR, but the UltraValve and an AVA preamp has made the listening even nicer...
What are u using for an amp etc?
Amp: Adcom 7500 150x5
Pre: Legacy NexStep (re-branded) ---> EAD Signature-8. was an Ovation-8 but had it upgraded. Excellent Pre!
Source: Oppo 83SE
Cables: All DIY (unbalanced, coax & speaker) except for the analog pass through that came from EAD.
AC conditioning: Shunyata DIY
room treatments - not all completed.
the Oppo is just a pricey transport. i keep trying and wanting the dedicated Sabre DACs to sound better in any regard
to the on board EAD DAC, but it just isnt going to happen. not that the Oppo sounds bad and i think it has a bit more resolution in the upper frequencies. a little more air. the EAD DAC is better in every other way. of course, that is in MY room, with an Adcom amp and DIY cabling.
my search for a tube amp is still there, its just slowed a bit. Frank's gear will be under consideration, of course. AVA and Salk is like porkNbeans according to everyone who has heard them together. i think Belles would make for a nice Adcom replacement.
still, my family is very happy with the current setup.
my STs were a bit thick in the mid-bass for about 3 weeks. thats all gone now and the change happened relatively quickly when it did. over about a 2 day period, all that gravy washed away.
