Vintage Denon Direct Drive Turntable

As I understand it, the 80 was issued after the 75 and weighs more and has better speed stability. Since I am planning to build a plinth, that would seem to be the table to acquire.

T_bone or Lewm, can you give me a link to the brochure?

I was unaware of the magnetic stip concerns, and would assume these are no longer made? Hence the sensitivity?

The 75 improved on the 80 in some ways, and was made afterwards, I bet to a slightly lower price point when sold separately to assuage fans of the DP-80 (Denon themselves were trying to bring the DP-80 to the masses based on the DP-80's critical success and Japan's economic development in the meantime). The Vinyl Engine is a fantastic resource for fans of non-current analog equipment. The library for Denon is here.

That magnetic strip is unrepairable, but necessary to the operation of the table

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 speed instability. Also, Denons are by far not the only DD tables that used the magnetic strip/tapehead as a way of monitoring platter speed. I have seen it myself on hi-end Sony tables of the same era, and I would bet there are others.

Tbone, you seem to know a lot about the history of these tts. Besides the measurements we discussed, do you know in what ways the DP75 was an "improvement" on the DP80, e.g., platter design or weight, electronics, etc? I had my DP80 electronically restored by a local pro who owns an SP10 MkII himself. He was very impressed with the DP80s innards and felt it was advanced vs the MkII, in terms of the circuitry. (This of course has nothing to do with sonics; I am not claiming that he said it would sound better.) Like Zargon, I was heretofore under the impression that the DP80 lived above the DP75 in the Denon model line, but I take your word for it that this was not the case. Or maybe the DP75 came along after they discontinued the DP80, in response to a perceived demand. Or maybe the DP75 was marketed more internationally vs the DP80, which was only made in 100V version (i.e., for Japan), as far as I know.

Dear Zargon: +++++ " Is this TT worth the time and effort? " +++++

yes, the reward is a beautiful one.

I own both units 80/75 and is very hard to say which one is more neutral due that both are similar and almost the same.
Differences are that the 80 has a pitch control that the 75 has not and that the mat are different: the one on the 80 seems more " dense ", anyway I don't use those mats.

Like in the SP-10 the Denon original plinths are not the best way to go so is here where you have to work to achieve a top quality performance.

I use two similar but different material build on these Denons: one is made from real marble ( a beautiful green one ) and the other from Onyx, I think that each plinth weight s around 60-70 lbs that as a fact function like " arm board " because the TTs " seats " on three ( small )polymer/plastic blend tip toe like a top the stone plinths and the plinths goes over AT pneumatic footers.

+++++ " I would be comparing it to my belt drive TERES. " +++++

you will be surprised how good are those Denons.
IMHO it is a good " move " to have two totally different TTs ( Teres/Denon ) .

Are at the same level that the Sp-10?, well IMHO they are aand are better looking " boys " due that the Denons were designed for people like you or me and not to radio-studio like the Technics ones where the " cosmetics " was not so important but even the DP-100 ( studo version ) is way better " looking " than the Technics MK2/3.

IMHO Denon has nothing to " envy " not only to Technics but to any other unit out there.

Regards and enjoy the music.
