Using CD player with outboard DAC
Try different coaxial cable too. Sometimes male RCA connector does not mate well with female RCA connector. 
Replace VPI TNT rubber belt with nylon thread
I agree with Ptmconsulting completely. I am using 0.004" nylon string with SDS controller.It sounds more detailed and clearler. Bass seems better defined. Sounds like high frequencies are better defined. It seems to have less bass, but bass is bet... 
Kef 107 woofer refoaming question
Thanks,I think I will try it myself. 
Vibraplane
sirspeedy: How are your friends using Vibraplanes with TNT6? You mentioned that the VPI suspension is a fixed one. Does it mean that they defeated their air suspension footers supplied with the turntable?I am also using TMC air table with TNT 5 an... 
Need MC Step-Up Transformer advice?
Hi Paul, the TX-103 that I was using was burned-in from Bent audio. I have asked for 100% burn-in, and John did it for me. I don't have any idea about how many hours is actually needed for a complete burn-in. I have assumed that Bent audio would h... 
Need MC Step-Up Transformer advice?
We need to speak from our own expreiences, not from "it must be....", especially when it comes to audio. I think it is really worthwhile at least to try some decently built pre-preamps a listen. From my exprience pre-preamps sound very good. In fa... 
Need MC Step-Up Transformer advice?
I second Raul's opinion. I have tried well burned-in S&B TX-103 transformers (also briefly Cotter trannies several years ago) in my VPI/Shelter 501/Counterpoint SA-9 in MM/Acoustat servo OTL power amps/Acoustat model 8's. The S&Bs were con... 
What is the best phono preamp you have heard?
Counterpoint SA-9 modified by Michael Elliott:removing 2 SS buffers, changing to Dynamicaps, removing MC stage, changing output volume control to naked Vishays, changing to high impedence circuit to have tubes directly drive output volume control,... 
RM-4 vs. MCP-33
I have 2 versions of the RM-4. The first one has only one transformer (later model). It has input impedence loading socket and output gain socket. I was able to have custom value male socket made by Music Reference. The output gain was not changed... 
ZYX RS20 vs Denon DL103
Flyingred:What is the effective mass for your Schroeder Reference?I am thinking about getting the 103R myself for my VPI 12.5 arm (11.5g effective mass). Lots of people seem to recommand high mass tonearms for the 103R. Thought about getting Airy ... 
RM-4 vs. MCP-33
S23chang:I could not tell the sonic changes of replacing the original caps with Dynamicaps, because I have changed lots of other parts together at the same time. I know I should have modded one part at a time. The original caps are yellow colored ... 
RM-4 vs. MCP-33
Raul:I have thought about using V-Cap oil caps. The Teflon caps are too expensive in my application since the RM-4 uses 5.0uf value. A very reputable person in audio modification told me that V-cap teflon is 9 if Dynamicap is 10. So, I am holding ... 
RM-4 vs. MCP-33
Don is right about Vishays. I have noticed the RM-4 to be extremely quite after installing Vishays (along with Caps).My cartridge has about .4mv output, so tube hiss is not audible at normal listening level. So, my analog setup is deal quite at th...
