Azimuth question
I think you have to ask VAC what is the sensitivity of those LEDs to signal voltage. At that point you would only know that your crosstalk is less than the minimum value needed to light up the LED, because the LED is "off", but it won't tell you b... 
Vintage DD turntables. Are we living dangerously?
Dear Doron, BA mats, brittle sounding or not, are not made of carbon fiber; they are made of graphite. (But I submit this with some trepidation, knowing now that you are an expert on materials science.) On two very different turntables (Lenco and ... 
Synergistic Research PHT - Phono Transducer
Just to say there are others who perceive no difference, with vs without their PHTs. If you are really curious, it is my understanding that Synergistic offers a free home trial. "Free" in the sense that after you pay for the PHT, you have the righ...

The funny or sad fact is that the mat has a large effect on sonics,…. after all the money is spent on the tt, tonearm, and cartridge. It's the salt and pepper of vinyl.

Banquo, Keep in mind that the recommended Redline viscosity, and this is only for the Kenwood L07D, is straight 20W, not a blend. So, if you can find it, maybe compare that to RP 20W. Or, compare Redline in the 5W-30 weight to the RP 5W-30 you alr...

Doron, You obviously know your stuff when it comes to lubricants. Thank you for the information, some of which I once knew but had forgotten. Your last remark is the focus of my question: Do you mean to say that there is some fundamental differenc... 
Triplanar vii - upgrade tonearm and ic wiring
I've never heard a Dolshi Alaap in my own home. I know that it is very well liked by those who do own it. But, and this is only if you are in a mood to fiddle, I do know one person who went from a Dolshi Alaap to a Coincident phono/linestage to an... 
Triplanar vii - upgrade tonearm and ic wiring
Syntax, Maybe you could see here that you are relating your opinion, probably based on listening in one of your systems. Your opinion is valuable, but it is not more than opinion. So are you suggesting that the OP can upgrade his system by selling... 
Triplanar vii - upgrade tonearm and ic wiring
Ralph, Do you really think the "old" wire interfered with tracking? That would have to mean also that the path of the wire through the arm wand and then down to the outputs via the vertical path, puts the wire in a position to interfere with the b... 
For VPI Unipivot Owners, do you use antiskating?
I'm with Al. Plus, "listen" for distortion that is worse in one channel vs the other. I sometimes get this wrong, but R channel distortion indicates maybe too little AS. L channel distortion the opposite. In my experience, listening is an even mor... 
For VPI Unipivot Owners, do you use antiskating?
I read PL's short treatise on AS, and it was unclear to me just what part of the LP he wants his disciples to use for setting AS. If you read his text carefully, he seems to be talking about the very short in duration end of play area, just before... 
Tonearm: Well Tempered Lab LTD MK2
First, do you concede that there can be no "pivot" without a bearing? If so, then you agree that the construct that permits pivoting is a bearing. I am not sure I understand the meaning of the term "zero tolerance". If it means that every tonearm ...

Johnny, I am very glad that the new Pioneer exists, because it will be attractive to those who fear "living dangerously" with vintage DD's, and it may help, like the Technics SL1200 did, to spread the word of the virtues of DD. But what "vibration...

Banquo, Re platter rubbing. There was indeed one point in time where I perceived noise coming from what sounded like platter rubbing, only audible at 45 rpm, and I reported it here. However, the noise or rubbing sound, or whatever it was, disappea... 
Vintage DD turntables. Are we living dangerously?
Thanks to Henry pointing out the clickable links, I was able to see the photos of the Jico mats. I definitely do not like the fact that the mat hangs over the edges of the platter. Most all LPs have a "lip" around their circumference. Optimally th...
