Vintage Denon Direct Drive Turntable
Tbone et al, In the DP80, when you use the adjustable speed control you are bypassing the quartz crystal oscillator. That's the only way you can get the electronics to agree to change the platter speed, I guess. If the electronics are all copaceti... 
Koetsu vs Dynavector
Halcro, I don't mean to take issue with your opinion of the Koetsu Urushi, but my experience is quite different. In my system I am getting great bass and fantastic treble from the Urushi. And of course the midrange is to die for. Whether or not it...

Stringreen, The magnetic strip issue has been done to death. If the table holds speed, you don't have a problem. If it does not hold speed, you MAY have a problem with the magnetic strip, but there are many other possible and cureable causes of sp...

I've got the same brochure that Tbone is talking about, from the Vinyl Engine. The one for the DP80 does quote a 77db S/N ratio, as he says. Both 77db and 80db are well below the S/N ratio of any LP playback system, so noise per se is not going to...

Thanks, T bone. I had seen those numbers for S/N in Denon literature. I look forward to the DP80 listening experience, if I can ever find the time to make or have made a plinth for it.

JLoveys, If your early expts excite you, check out the PTP2 top plate for the Lenco (on the Lenco-Lovers website). Not only is it far more rigid than the chassis of either a stock Lenco or a Garrard, it also permits a large area of contact between...

T bone, thanks for your insights. I am wondering about wow and flutter in a turntable, which would be reflection of speed irregularity rather than noise, I think. In the brochure for the DP80, Denon claims unprecedented speed stability, so whateve... 
Belts vs Direct Drive and correcting experiments
Mea culpa. According to Wikipedia, the terms EMI and RFI are synonymous. And that seems to be correct based on a dim memory of previous reading. Don't know where to go from that. If anyone hears a difference with vs without a shield, let me/us know.

Dear Raul, If I write enough words, eventually I will make some sense. Thanks. Audiophilia is nine parts worrying about non-problems and one part solving actual problems. The vendors benefit from all ten parts of this obsession. I think now (based...

Donshoemaker, I don't know the difference between a DP80 and a DP75. I've already sold the DA307 that came with my DP80, and I did notice the rubber bushing that comes BEFORE the pivot point, which looked like a bad idea in principle, but lets rem...

Kcc123, Aha! I see that the DK2300 plinth is a two-armboard version of the DK300 that I own with my DP80. Thanks for the photo. Since you have owned your tt for 30 years, can you tell us if you've ever done ANY maintenance on the tt bearing? This ... 
Belts vs Direct Drive and correcting experiments
I was thinking about this hypothetical problem this morning in the shower. It seems to me that the cartridge itself might provide a low-pass filter that would prevent any RFI emanating from the electronics of a DD table from entering the downstrea...

Zargon, the DP80 per se is one of the best of the Denons, and in my view and according to one person who owned both in recent years and used them with modern tonearms and cartridges, may be just as good as a Technics SP10 MkII. At typical prices, ... 
Vintage Denon Direct Drive Turntable
What then is a DK2300? Is it Denon terminology for a DP80 installed in a DK300 plinth with a Denon tonearm supplied? If so, what tonearm do you have? After all, the sound of the unit is going to depend more on the tonearm/cartridge synergy than it...

For my SP10 MkII, I wonder whether Albert is willing or able to sell a copy of his shield/platter mat. I will ask. That would save a lot of thinking and making.
