What happened with the SACD format?
Red book playback on the better transports and processors is getting so good that SACD is no longer the next step up in digital as it was in the past. 
RTR esr 15 info
Years ago, I combined the Acoustat 1+1 with 16 RTR elements in a line source, which were absolutely superb. I ditched the Acoustat HF transformer, as it muddied the sound and reduced the efficiency of the panel to force the extended HF response of... 
What do you think of a Sonic Frontiers Processor 3
Superb processor. The SE version is an improvement over the stock Processor 3. I have owned the SFD Mk II, and the SFD Mk III, as well as the SE version of the Processor 3. The SE Processor 3 is superior to the SFD III stock. According to Chris Jo...

The best speaker you ever heard?
There are two. 1) Acoustat 1+1 & RTR ESR 15 disassembled, and arranged in a line source next to the Acoustat panels, with the Acoustat HF Transformer removed, which allows you to use natural roll off of Acoustats crossing over to RTRs. It also... 
Anyone had experience with Opera Audio Cyber 211?
Very nice looking, even very striking, however, lacks low bass as well aslower midrange richness, seemed somewhat veiled, and seemed to lack an extended high end compared to Canary,PP 309 300bs, as well as a pair of Modded Consonance M500s. The 21... 
Anybody heard Stereoknight magnetic preamp?
Simply superb TVC, I have the balanced silver edition, and it is heads and shoulders above anything else I have tried. I have used active as well as passive, including the Prometheus reference TVC, the Reference Line 1a with silver wiring, etc, an... 
Floor Standing or In Wall speakers
I have been wondering about this issue myself. I had planned to use a pair of inwalls for the main speakers in a music room, as the existing stereo system uses larger sized speakers, and the second pair of home theater speakers is somewhat clutter...

Yamaha Rx-V1 Channel Drop Out
I have found the dreaded channel drop out is caused by dirty contacts in the switches (which disable the amps when an interconnect is inserted into the rca plug outputs) It will show up even though you never have used external amps. The solution s... 
time to discuss kt-88's
One thing I don't see discussed much, except in this posting is the compatabity issue. Bias voltage, and plate voltage seem to be different for this tube, and they don't seem to be a drop in substitution for Kt88s, or 6550, if all paramaters are n...
