Hi lewm, thankyou for your informative post, I enjoy learning, we did listen to a whole lot of equipment to come to our impression's, our goal was to go back in time to hear if anything was as good as today or better, we got frustrated with the notion that newer was better, we'll, the consensuous was wrong!, I suppose that getting jensen or murdof capacitors is inadequate for none signal capacitors for the technics sl 1600mk2 turntable we hand picked out, I would enjoy all the help from you and anyone else, as far as the main system you asked about, it is the only modified krell 700cx out there according to krell that we spent the $11,500.00 doing so back in December 2014, then I'm useing a digital player that we got rid of an ayon cd2s player for called, Vincent cds7 , btw, we run directly to the Krell 700cx amplifier, then, we have taralab's zero gold XLR interconnect between them, speaker cable's are taralab's omega gold speaker cable's, with special order omega 10" speaker jumper's for bi-cableing the 4 speaker post on our jbl L7 vintage speaker's, btw, just bought the mint second pair after selling the first L7 speaker's thinking we would go up to any $25,000.00 new or used speaker's, that expenditure was a bummer, so we looked long and hard and found mint condition jbl l7 speaker's, paid $ 400.00 shipping out of new York city to Mobile, Alabama, useing plycon furniture and automobile transportation group carrier, I also use a taralab's oyaida terminationed Cobalt power cord, with furutech gtx-rhodium NCF outlet's through out the system with dedicated lines we did our self's, so the main answer to your question about the analog turntable, we do not use or have a active pre-amp on main system,cheers.
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.

So Harry is making his VPI Direct even better... https://www.audionirvana.org/forum/the-audio-vault/analog-playback/turntables/10314-peek-at-vpi-aven... And in the latest TAS, JV talks to Gunther Frohnhoefer of Acoustic Signature on his latest Invictus belt-drive and asks him about the "comeback" of Direct Drive... Yes, I know there has been a little comeback of direct-drive motors. Invictus is a cost-no-object product. If we had thought a direct drive motor was significantly better, we would certainly have made an investment to design it. Yes, you can get better wow/flutter values with a direct-drive motor of high torque. This is the truth and nobody can deny it. Not even me. But at what price? Sounds a little defensive to me.....😎 |
Halcro You have edited out the most significant comment by Gunther Frohnhoefer of Acoustic Signature with regard to wow and flutter But, yes, the direct-drive motor will still produce better wow/flutter values because we use belts, and belts are worse in wow and flutter than a direct-coupled motor.It appears that they use stretchy belts. I suspect they have focussed on lowest noise and the stretch belts are a bandaid. As an aside he claims the 6 AC motors get the 32kg platter on the Invictus up to speed in under 10 seconds. My Final Audio VTT1 which uses one large AC motor can get its 26kg platter up to speed in less than 1 revolution ( 1.8seconds ). So I can only conclude that the Invictus uses weaselly motors and stretchy belts. I also owned a Platine Verdier - weaselly motor and stretchy belt - the replacement of the Verdier drive system with that from the Final demonstrated clearly that low power motors are a source of instability even when using high inertia high mass platters. For best speed stability in belt drives you must have high inertia, high torque stable drive system and non stretchy belt such as silk or kevlar. I also note that he comments that compared with Direct Drive motors he can get high quality AC motors at lower cost. He seems oblivious to the possibility of using AC motors in DD's or Induction motors for that matter. Overall I am not impressed and sceptical about a TT, the Invictus, that has no published specifications on performance nor any technological information available. Furthermore their Tiderfolon bearing is simply an self lubricating material - it is not possible for it to be frictionless as claimed on their website. I use a custom self lubricating polymer bearing in my 1960 Pioneer broadcast idler drive TT ( that blew away the Platine Verdier in speed stability ), its not that radical. |
Halcro Dover, Unless I was prepared to type out the whole two page interview here...I was bound to leave out many things he said. I think it's debatable what the "most significant comment" may be..? |
