CSPort vs TechDAS


Looking for any non-dealer opinions on the sound differences between CSPort vs TechDAS.  TAT1M2 vs AF3PS.  

Thank you!

Dear @chauncey  : By design seems to me that the Premium S is a little superior to the CS Port and real measurements confirm it where the speed stability of the PS is really superior that the CS Port. Both units use a quarz oscelator on its motot ps better implemented in the TecgDAS.

@sksos  posted: " is a far more neutral sound .. ". I respect his opinion but almost has not a good foundation and not only because the measurements says can't be that way but because the resonance frequency between the MSL Platinum and the Safir tonearm ( that's the combination he shows in his virtual system. ) is to low at 5hz and we have to remember that the Safir is a four point unipivoted design.

 

This is the review and true/real measurements not did it by TechDas as the CS Port manufacturer specs but measurements by a third " hand " and this speaks a lot about that comparison between TTs. The other issue is that the TecgDAS is the Premium model where the Premium S is even better:

Btw, servo in TT if it's well designed and with good quality excecution never is a problem with the sound we listen through it and we have to remember that all the cutting machines in the recording proccess comes with DD motors and all those motors control its speed by servo. That means that if we can't be aware of the recording used servo then it's no trouble at all. In several TTs the servo is only one characteristic of several other more important parts/characteristics in the TT designs: quality level in the excecution design could be the name of the game down there. Just my opinion but as with sksos y heavily respect the @mikelavigne  opinion about.

 

Regards and enjoy the MUSIC NOT DISTORTIONS,

Have you ever had a turntable with vacuum hold down?  I'm worried my Sota table now has a vacuum hold down and I would miss getting that record perfectly flat held into place?  I assume at a micro level the air under the record and the pulling down of the record varies with the pump action?  I guess the same could be true of the air holding up the platter.

@chauncey

for 8 years (2002--2011) i owned the Rockport Sirius III with vacuum hold down. very high level of execution. but it does add a level of complication to the design. fabulous turntable. i wish i still owned it.

i am neutral about the effect of vacuum; it does flatten warps, but the actual times when it helps are very few. it’s very rare when i notice a warp effect in my listening, and not had vacuum since 2011. and when i compared the Rockport to the NVS and other turntables i owned at that time i did not really hear much difference in that regard.

and it’s possible a record weight has advantages. and vacuum can be too much of a damping effect too.

overall i would not buy or buy a tt due to vacuum. more just the overall performance.

i do own a flattener, but have never used it.

this box set is very good, all analog reissue of 4 symphonies. very good sound. quiet pressings. worth finding. one of my frequent choices.

yesterday this is the one i was listening to;

on the CS Port was a pleasure.

note that i am no classical expert, but a constant Lp classical consumer and lover. which the CS Port perfectly compliments.

Dear @chauncey  :  Mike is rigth with him and his targets when said: " overall i would not buy or buy a tt due to vacuum. more just the overall performance. "

 

In the other side the vacuum hold down TT characteristics is a important " plus " in any TT at any price level. We have to remember that at the micro levels where the cartridge stylus tip is working during play exist micro-warps that puts an additional not desired " coloration " to what we are listening. The vaccum helps a lot too in the LP parts recorded at high velocities helping the stylus tip to track with more applomb and pick up better MUSIC signal from those groove modulations. Vacuum due a lot more for the quality level performance of what we are listening . No, it's not true that the vacuum can be to much effect damping as Mike said because what any one of us in any room/system need is the best damping we can achieve precisely between the LP and the TT platter/mat because is the first step in the playback overall proccess where we need try to " stop " the present feedback between that platter/LP surface developed by the stylus tip tracking and other developed micro noise/vibration down there: NEVER is to much damping down there. What we need down there is that the cartridge cantilever movements came with only the movements developed by the groove modulations ( MUSIC signal ) where this is imposible to can happens. Vacuum permit lot lower " fake MUSIC " movements in the cantilever because those overall movements are what the cartridge/transducer transform and that transducer does not knows if all those cantilever movements are only MUSIC signal modulartions but proccess all movements as if all were MUSIC signal.
