Vintage DD turntables. Are we living dangerously?


I have just acquired a 32 year old JVC/Victor TT-101 DD turntable after having its lesser brother, the TT-81 for the last year.
TT-101
This is one of the great DD designs made at a time when the giant Japanese electronics companies like Technics, Denon, JVC/Victor and Pioneer could pour millions of dollars into 'flagship' models to 'enhance' their lower range models which often sold in the millions.
Because of their complexity however.......if they malfunction.....parts are 'unobtanium'....and they often cannot be repaired.

Dear RichardKrebs:  "" We do not listen to specifications.
If we did, tube equipment for example, with its typically inferior measured performance, would be off our Christmas shopping list.
My view is that we can hear way deeper into the output of a product than measurements can articulate. ""

Agree, we listen to sound waves in the air. I think that the whole true hig-end audio community is " suffering " a historical trend/cancer  where almost no one really cares on what we are really listen to. That trend said: " the best judge are your ears ".  Audio retailers, reviewers and almost all the audiophiles ( like you . ) believe that's the " Byble " and that's all about and is not a fault of any one of us. As I said is just that trend/cancer that corrupted our today hobby.

Tubes is a very good example of that corruption but this is not the thread to talk about.

I don't " blame " you in anyway because you did not measure before and after, almost no one does, but could be really interesting for you ( the " creator " of that mods. ) where you are " seated ". If you want to disclosure to the audio community or not: this is your privilege. I can tell you that if I decide your mods to my units I really like to have those " numbers ": before/after.

I remember, many years ago, when was developed our phonolinepreamp ( Essential 3150/60. ) that its " sounds " was just " fabolous/spectacular " against what I heard on top similar audio units and for us was not enough our subjective judgements and we measured that unit and found out that its numbers were " unvelievables " ( example: even today the best units can't approach or beats our fully analog RIAA deviation: 0.012dbs! ). These gave us certainity on the why's and what we were " proclaming " in the whole quality performance of that audio unit.

IMHO, subjectivity or objectivity alone means almost nothing. My opinion is that both " words " are faraway from be one against the other but that exist an intimate realtionship in between and IMHO we need to know it instead that: " I like it ".

Richar obviously don't take the " road "  posted here:

"   People don't know what it means anyway. Imagine a turntable going from 70dB S/N to 90dB !! You could pretend to rewrite the laws of physics with some doubletalk  ..... "

that IMHO is almost an " insult " to the audio community but each one can gives its opinion in this " free world ".

Thank's for your answer.

Regards and enjoy the music,
R.

It seems my joke/sarcasm went over your head, but that's understandable given a previous post:

**Lewm, just think this:

suppose that your unit, before the mods, was running on manufacturer specs. Example 92db on SN ratio: what if after the mods that " figure " gone down to 84db?**

You were talking to Lew about Richard's mods. Before this post I would have guessed that everyone on this thread knows those S/N figures on a turntable are impossible. 

S/N ratio on a component like a preamp is referenced to an output voltage level. S/N on a turntable is a rumble figure and is limited by the dynamic range of a record. Maybe you'll tell us you meant something else, but that was the topic.

I deleted an earlier post which I thought might be too harsh.

Happy holidays,


I own two technics sl1200mk2 silver, and one sl1200mk2 black. Still use them, 25 years still perfect.  Silver ones stored for 15+years, unboxed, opened up, cleaned spindle, added fresh oil, plugged in, and pressed start, and still perfect.....they don't make me like this anymore, that's for sure. 

Halcro,

One thing I've been meaning to ask you, do you know why your 101 sounds better without the metal cage around the motor unit?

I don't have a plinth or stand alone design for my 81 yet so I can't try it, but I also can't come up with a reason why this should be so. 

Regards,
