I see, we did misunderstand each other. By suspension I meant, and always mean the way how platter is handing in its position: ball bearing, air, magnetic, liquid, superconductor antigravity, unobtainium … etc. I never pay attention to suspension of plinth and isolate it from floor and I feel that this is not TT duty, at least not a part of high-end turntables. I do not insist that my definition of “suspension” is accurate but this is how I use it for years: for me suspension is how platter is suspended, not plinth.

Naturally the manufacturers that offer it will say it is great and the ones that don't will say it is terrible. For my versa 1.2 I can easily adjust the amount of vacuum applied and the more I apply the better it sounds. By "negative curve" I guess you mean the platter is slightly dished? The Well Tempered turntable used that design. It does work well, but not as good as vacuum in my experience. |

I had the vacuum hold-down, Micro Seiki RX- 1500FVG. The hold-down worked great but I did not really felt any need for it. I hardly ever use warped records. I feel that the benefit of vacuum hold-down is to establish with a uniform bund between platter and record. The fanny part is that the leaves of vacuum hold-down act as gaskets between the uniform bund. Anyhow, I was not too wild about is and I found it was not too practical, even on Micro the vacuum hold-down was made in the most friendly way I even seen. Adjusting the amount of vacuum applied to get better sounds? Well, do you do it for each record? There are half of hundreds of records type, different thinness, mass, flexibility est. Do you set own depth of vacuum for each record you play? I do not adjust VTA when I play different record thinness. I assure you that move VTA from Dynaflex to 180g and I assure you that the sonic difference in VTA 100x time more than changing the depth of vacuum. Sure, I would not argue and it you see the improvement (not difference but improvement) than it certainly a way to go for you but it appears too anal retentive for me, at least in context of dally use. The changing pressure I feed my Vibroplane and to change the Vibroplane height also makes some difference in sound. However, I recognize those differences as something that is well beyond of my interest
