Gain and Loading
One approach to adjusting the load resistance is to start at 47K ohms, as you have done, and gradually reduce the value while noting any changes in apparent gain. When the volume at a given gain setting starts to decrease in relation to reducing t... 
Tri-Planar with no anti-skate?
Thanks, Doug. Sirspeedy, you must live in the DC metro area, as I do. I too was a longtime friend of Herb Papier's, and my experience of him was much the same as yours, i.e., a great guy. I met Tri Mai at Herb's house, when I went there to have He... 
Tri-Planar with no anti-skate?
Doug, As regards the drastic reduction of the anti-skate weight on the Triplanar, do you recommend it for all cartridges or only those with line contact styli?I have a Koetsu Urushi, which I would guess has an elliptical stylus. Does anyone know f... 
Installation Instructions??
Have a couple of gin and tonics before you start on this task. It will increase the likelihood of a disaster but drastically reduce the chances that you will care a lot.BTW, I have done it several times with nude cartridges (Benz, etc) and never h... 
Installation Instructions??
Tweezers. Borrow a pair from your wife. Needle-nose pliers are too potentially damaging to use for this job, IMO. If you squeeze too tight while concentrating on mating the connector to the pin, you can narrow the opening and thereby lose all hope... 
Micro Seiki MA707 vs CF-1
Thanks, Clio09. If you subtract the 707 from the 505, you have the 202. Until I saw that M-S 99V turntable for sale here a few weeks ago, I did not know that the 202 tonearm existed. My gut instinct was that the 202 could not be as good as the 505... 
"S" shaped tonearm ?
'feil, I take your point about engineering principles, etc, but the audio hobby is replete with examples of real world experience running counter to science-based expectations. So, you must admit that, for a given individual with a given turntable... 
Micro Seiki MA707 vs CF-1
Thanks, Clio09. That's about what I had come to believe from seeing photos on-line. So I gather that the major if not the only difference between the two is the carbon fiber arm tube on the CF-1. If I see an "MA707" with a black arm tube, I then a... 
Xv-1s competative carts mention in latest TAS
The last two over $5K cartridges that anyone sent him. 
Does it really get any better than the Raven AC ??
Can you tell us, compared to what? 
BAT Preamps, why such polarized opposite opinions?
Much of the sound of a BAT preamp as compared to most others is likely due to their preference for oil caps (high quality copper foil in oil, I think) as output coupling capacitors. Some DIYers love the sound of oil caps and some don't, but the de... 
the 47 lab RS-A1 arm, and it's clone ?
Someone else did not make it to the shower on time. It sold. And not a bad buy at that. Congrats to the buyer, if he read this thread, and please report to us your impressions of that weird yet wonderful gadget. 
New Teres Direct Drive Motor Available as Option
Or, if you want to get fancy, the best strobe/disc I know of is sold by KAB. Worth the reasonable cost, IMO. 
New Teres Direct Drive Motor Available as Option
I think I remember that the Shakti stone does have the property of soaking up some of the stray fields radiated by transformers, over and above the fact that mass loading the tranny helps to reduce vibration. I also think I read that any old out o... 
New Teres Direct Drive Motor Available as Option
Did you try a plain old brick or rock or piece of slate as a control for the benefits of the Shakti stone?
