Denon direct drive turntables

[Shovel_Knight]

I recently repaired a Denon DP-2000 turntable that was in a sorry condition. Had to replace all electrolytic capacitors and a bunch of semiconductors. I mounted my Mission 774 with a cheap vintage cartridge (Ortofon VMS15XE), connected it to a DIY phonostage and was rewarded with a very pleasing sound.

What really surprised me is that its character is completely different from my Technics SP10 mk2. The Technics is all about effortlessness, precision and control. It faithfully reproduces what's on the record. The Denon is lush, spacious and smooth, kinda "romantic" sounding but in a good way. It's definitely not the cartridge because I'm very familiar with Ortofon VMS cartridges and they don't sound this romantic on the Technics.

Frankly, this experience got me interested in their "big" motor units - e.g. DP-6000, DP-7000, DP-75, DP-80. DP-2000 was near the bottom of the range, the model number is a bit of a misnomer, it really is DP-3000 with quartz lock so they should have called it DP-4000

If anyone has experience (positive or negative) with Denon direct drives, especially the upmarket models, please share them in this thread.

I've not heard any old Denon direct drive turntables, but your description of its sound character does tally with that of my old Kenwood KD-990 which does play music rather like a top-end Nottingham Analogue deck but with a definite sense of added 'drive'. I don't know how the Denon DD motors were constructed, but I'd not be surprised if they used flat wound coils like my KD-990, which Technics have since adopted in all their current DD turntable motor designs

I recently sold DP55F and your description mirrors my experience. I hate the phrase, but it’s more ‘musical’ than I’ve found Technics decks.

I only sold it as I’ve got Sony TTS8000 and while the Dennon’s great, it didn’t bring more to the party, so, along with high end Dennon, I’d add Sony to the list. Ps 6750 was a great integrated TT.

It's definitely not a coreless DC motor, in fact it's a very impressive AC servo motor that is large and powerful enough to drive a washing machine.



I noticed that the servo is very gentle, if I try to stop it with my finger, it doesn't try to tear it off, and if I remove the pressure, it just instantly gets back to speed without any overshoot.

The 2000 turntable uses an induction AC motor which is powered by a separate winding on the power transformer.

Yes! It is an ingenious system, very similar to what Sony did in TTS-2500 and TTS-4000. There is a large power transistor in series with the motor windings which throttles the voltage applied to the motor and controls slip between the rotor and the rotating magnetic field of the stator.

I am a huge fan of old high-end Sonys, and in fact from the technical staindpoint the DP-2000 is very similar to Sony TTS-2500, with the added benefit of quartz lock.

Blimey - that's quite a beast!

Does that include the PS B80 which I have and enjoy very much

Unfortunately, I have never heard a Sony turntable with a Biotracer tonearm, but I know that they are supposed to be bloody amazing
