Upper Level Vintage DD Strenghts and Weaknesses

Vintage DD, Quartz Locked, YEAH!

To me, it’s a visual preference, I like the JVC spinner look more than someone else who prefers the Denon look.

A few Pioneer semi-automatic wood base tempted me, but I went for TT81 in JVC 7 layer 2 arm-board Plinth. Had I known, and where I ended up (3rd arm squeezed in) I might have gone for the rare and bigger plinth with 3 removable arm-boards.

The 7 layer plinths of either Denon or JVC-Victor are terrific, and the real wood veneers are very nice. Some vintage TT’s are wood looking vinyl. No functional difference IF it has the 7 layer construction, just if you care (I like real wood).

I researched, decided the TT81 was the one for me, (actually a TT71 is also quartz locked, I just came across TT81). I typically try for a level below the top, i.e. the more advanced 101 or 801, even if I won the lottery, would give me nothing audibly different, potential problems, decided not to go there.

That Sony (I read about it, I forget, metalized plastic?) deck, even if technically/measurably better on a test bench, didn’t appeal to me, it would reduce the pleasure each and every time I glanced at it. Someone else, it’s the greatest. But then it seems you get a potential bearing problem with their TT’s which I would likely not have been aware of.

I agree with chakster, add a layer of isolation under any TT, I went for a variation of these below the factory adjustable leveling feet

I was going to conceal them with a skirt, but Donna likes the light coming thru under the TT so maybe I will go for something more attractive.

So far the front runner is going to be a Denon DP80 and possibly a DP75. If I did the DP80 it comes in the Denon DK300 plinth, and that one looks to be pretty well made. This is the one I am considering, although I don't know the tone arm packaged with it.

There is another one of these tables with an Audiocraft AC3000 attached in the same plinth and its $400 more. I might see if they will swap arms and I pay the additional monies as that arm is a good buy even though I don't need it for this project. 

The other option is here on Audiogon and that is a DP75 in a VPI plinth. I have owned that combination before, and to be honest the plinth is pretty primitive. Its redeeming feature is that massive top plate. The springs are problematic and no way to tune them. But its an attractive combo, but does not have an arm board. Its drilled for the 401 arm, but the mounting base to the Dynavector DV505 should cover that hole.

Now if I did buy a DP80 this is my end goal of table. Perhaps not the electrical modifications the person has made, but the plinth is the appearance I want to go for. I suppose I can reuse the DK300 plinth and put another Denon table in there for resale with the less expensive arm if I go that way. But this way the DK300 plinth can be a stand in and allow me to play the table while one like this is built.

It’s top quality and heavy plinth, DP-80 is a killer DD, you just need a decent lightweight mat (I use modern Graphite mat on my DP-80).

If you never tried original Denon plinth you have no idea what is it, it’s better than you can expect!
Do not try to make Denon look like Micro Seiki with that ugly plinth for 3 tonearms. 

Just respect the aesthetic of Denon, it’s proper engineering from plinth to turntables, tonearms and cartridges.

"It’s top quality and heavy plinth, DP-80 is a killer DD, you just need a decent lightweight mat" 

then

" Just respect the aesthetic of Denon, it’s proper engineering from plinth to turntables, tonearms and cartridges."

So how can Denon have proper engineering in all aspects and then not do the mat right? Seem to be contradicting yourself here. 

Eh I will do what works for me on the plinth. You may not care for the aesthetics, but not everyone has to like the same things. You do you. 

Most of the vintage Japanese DD turntables were sold with thick floppy rubber mats. Most sound better with replacement modern mats of one kind or another. This is just a common observation borne of a common experience. It’s not evidence of a design flaw. I agree that the DP80 or DP75 is best bang for the buck. However beware of examples that were built for 100V AC in japan and then subjected to 120V in the US. Such abuse can have damaged the single IC in the control circuit. 100V models are absolutely fine otherwise but you need a step down transformer. The OEM plinth is also ok; I had a slate plinth with an isolating suspension made for mine.
