Hi everybody,
I would like to point some technical things about these turntables; the Denon DP80 and the Yamaha GT2000. I know that some of these things, are had said here during the thread develop, but it will serve also for to complete my intervention, as user of both pieces, sometime ago.
At very first place, both machines are from very different technologies: the Denon uses a traditional 3 phase AC motor and the Yamaha instead, uses a BLDC coreless motor, a “pancake” flat type. This fact, could be a big difference, especially under the point of view of the “micro details”, being the coreless motor a big advantage against the traditional motor. And I say “could be” because the machines must be both in its better and near-to-ideal running conditions, for to make it comparables, at least, under the music-listener point of view.
Second, the Denon must be installed in a plinth of the same quality of the Yamaha, for to make valid the comparation. Besides, both turntables, must use the same tonearm. May be, using the Yamaha tonearm installed on the Denon. In fact, I have seen on the internet, the Yamaha tonearm for the GT2000, alone. Anyway, I have used the Denon with some Denon tonearms; like the DA308 and the DA309 (12 and 10 inches, respectively).
Before to go forward, I would like to say that BOTH turntables are very, very good machines, regardless its technical characteristics or datasheets, and the differences, enters in a land that I can clasify of “personal tastes affairs”. More yet, oneself can likes more one of these TT , a certain moment, or the other one in a different moment.
If I would must use the Yamaha's slogan “Gigantic & Tremendous” I would use it for the Denon DP80, instead.... Yes. As all of we knows that the heart of any turntable, is its motor, the Denon's one is actually enormous. By the other hand, the Yamaha's one is more or less small. But they (Yamaha) have used a very big plate. The Yamaha's motor, is no more than one like used on the JVC QL-Y5, a very good turntable, but never considered by the popular "hi-end" market, like as other brands with better advertising. More yet, the engine used by the JVC (on the QL-Y5) have some technical refinements that are not present on the motor used on Yamaha GT2000. And the JVC's motor is far older than the GT 2000. More yet, the motor model used on the GT2000, seem to be an OEM version, made surely by JVC... In fact, seeing carefully the GT2000 motor, is possible to see the same label used in the motors made by JVC.
Talking about modern motors (newer that these used by the Denon DP80), I can say that the motor used on the JVC QL-Y66F is BIGGER than those on the Yamaha GT2000, and also; far more refinated technically. The big QL-Y66F's Achilles heel , was its very weak plinth.
Returning on the Yamaha GT2000, its Achilles heel instead, is the tonearm. Using an honest one, like the Denon DA309, is a bit better. So I think that using one these high quality ones, the whole performance could arrive to unsuspected levels.
I have done many experiments with many motors units, also with motors alone and custom plates, different tone arms, etc. One of my favorites (but not the only one), is the Technics SP10mkII with the Dynavector DV-505 tonearm, mounted on a my own design of plinth. A truly delicious, complete and energetic sound, even with a motor "core type" (not coreless). Technics never entered to the “coreless” arena, until now. May be for commercial motives or so. Anyway, only at the last production, Technics have included the “coreless” motors in the latest models, but those models have high prices, like the SL1200G, SL1200GR, SL1200GAE and the newest SP10R, that until now, the price is unknown, at least in Europe. All of them, from 2016 onwards. OK, finally also Technics is convinced that said by JVC 50 years ago, yes....half century ago !!!!.
Returning on our Denon and Yamaha, as said before, the better one depends on the personal tastes. Both of them are fine machines. The Yamaha could be better yet, if it is provided with a better tonearm.
cheers !
