    The principle is that in a suspended turntable the platter will apply a force (torque/twist) to the suspension as it rotates. Some say this gives them their reputation for sounding "laid back" or creates a slight blurring effect on the sound. The bottom platter is there to counter this force and by doing so creates an extremely stable platform that is isolated from all external interference. I don't have enough experience to tell you if the "laid back" thing is true but I can tell you after owning a Sparta and now the Pro the two platter thing definitely works. Both the Sparta and Pro are extremely high resolution, image spectacularly, and are extremely quiet.

    The differences between Sparta and Pro are the 12" arm, the plinths are sandwich phenolic (vs skeleton), and the platters are heavier with beefier motors. Louis tells me the plinths make the most difference in the sound (and most of the price difference as well). The second big difference is that you can use the SCPS with the Pro. Two banks of super capacitors that switch every 60 seconds and provide ultra low impedance output to the DC motors while completely isolating the table from the power grid. Kind of sounds like a bit of a gimmick when I tell you the power supply makes a major (not minor) audible difference to a turntable but it's true.

    Anyhow, sound is excellent. If you guys are interested I can do a few needledrop samples; hit me with some requests. I do a lot of LP transfers for my DJ gigs so I am very much looking forward to getting started with these.

    Nice, and really interesting deck/arm combinations, but let's get some carts mounted up so they're not just display items!

    hardly display items they're well-used. :)My main carts currently are a VdH Colibri and Transfiguration Proteus. I took these pics for the insurance co. before they were boxed up. i'm in the middle of a move (divorce).

    Finally got this up and running. @Wfojas sold me the package for an unbelievable deal for a while back. VPI TNT 3.5 with the air ball feet (need to pump up with bicycle tire pump), two platters (lead/delrin and aluminum), periphery ring, and SDS - just no arm. By fortune, I happened to have a 10.5 arm sitting around which I originally intended as a second arm my Classic 4. The person I bought the arm from said he wasn't including an armboard, but when it shipped, it happen to come with the armboard. I decided to experiment and use a nylon string instead of the stretchy rubber band from VPI. It's amazing how vinyl sources can bring magic mediocre setups (BW speakers and proamp) such as this one.

    This is a really interesting idea. You're using a nylon string in place of the belt? I imagine the tension would be distributed more evenly this way since the nylon string is less elastic than a standard TT belt. Was that sort of what you were going for? Now I'm curious if it would be possible to measure differences in speed stability between the two

    Is some amount of stretch desirable? I am curious how you made a loop out of the nylon string. If it is as simple as tying a knot, you might want to check out fishing line. There is a huge variety of styles and gauges with varying degrees of stretch.

    I think
    i included the two armboards, i didnt need them, in case you wanted to use a triplanar or SME, too. Or an ET-2, I think. A couple of things can still change the sound, stuff I never got around to. You can change the suspension with squash balls and a flat plate (VPI is out of them but they are fairly common). A rim drive which is more challenging to find, two belts work better than one for sure ( ask @shaizada for a cheap place to get them, like $7 each, i think), different clamps change the sound. Good to see you got around to getting them together. Now you hear why i said warm by default?

    Yeah, just simple knot for these thin strings. I'd go for a bloodknot for thicker strings. So far I've tried dental floss, nylon, silk, and fishing line. All very similar results, but decided on the nylon. The concern with the elastic belts is that their tension may vary throughout the length of the belt. We just don't know how one part might stretch differently from another part as the belt drives the platter. Multiple belts are certainly better than one. I have two VPI belts running on my other TT (the Classic 4) and am thinking about adding another. I tried using a nylon string for the Classic, but because of how the motor is coupled to the pllinth, I get sympahetic vibrations from the tensioned string and motor.

    The effect of the nylon string compared to the VPI elastic belt is similiar to a jitter reducer with digital. More focus, less blur, crisper transients, blacker background. There can be too much of this and hence why backed off from silk to nylon. Yes, I can measure speed stability. Will do this when I have time.

    The other armboards will come in handy in the future. I have my eyes set on a triplanar, mainly because I love how it adjusts and appreciate the engineering around it. I might grab one of those fancy $$$ Stillpoints clamps. I am not a big fan of the screw on clamp for the VPI tables. Seems to "choke" the sound. As far as warmth, not as much as I thought. The nylon thread might have pushed the sound a tick more in the leaner direction, but tonally, the table does not sound far off from the Classic 4. I was actually expecting more warmth. The aluminum platter probably has a lot to do with it. Also, I think the 12" arm (on Classic 4) that I have (metal wrapped with a vinyl or rubber sleeve) is warmer than the 10.5" arms. The 10.5" arms seem to sound more "precise and concise", the 12" arms have more flow.

    I am actually shocked how good these vintage TNT tables sound. Certainly a lot of more room to tweak and play with than the Classic tables.

    You should try it with the Kuzma, that really does put it over. I just sold a Stillpoint LPI, I would have asked you had i known. That tends to reduce overall dynamics a bit but pushes voices into a really sweet light, but depending on how the recording was made, can be a bit much.

    nd yeah, the platter definitely does lighten up the sound. Also, the air bladders should be inflated to as just they firm up. Too much, and the isolation is reduced, you could try varying that too.

    So many things.

    At the risk of entering audio nervosa territory, I would recommend trying flourocarbon fishing line if you want to experiment more. It has less stretch than standard nylon monofilament, but more than the silk thread. The trade off is that it transmits more vibration than nylon.

    The big downside is that some of the cheaper lines tend to deform when stretched instead of springing back into shape like nylon. That might get annoying for your application.

    Totally agreed on the engineering of the Triplanar. However, knowing how you appreciate resolution and detail, I might suggest avoiding the Triplanar. As Willy says, Kuzma is probably the way to go and you'll have no lack of appreciation for its engineering...

    Not into this stuff that much, but I've heard lots of good things about Kuzma.
