Sprung vs Unsprung VPI Turntables.

I'd be suspicious of any dealer making the claims you are stating. As I understand it, quality acrylic in sizes needed for large platters (2+ inches deep) is getting hard to find. So VPI's change to aluminum has more to do with materials availability at a price than anything else. Besides, aluminum is easier to machine consistently. As far as the motor is concerned, the aluminum platter is of a similar weight to the super platter, or at least close enough that it requires similar torque. If VPI really wanted to cheap out on the motor, they would have stayed with a lightweight solid acrylic platter (although cogging then can become more apparent.) What is lift power by the way?

I have a Fully Updated VPI HW19 MK.IV, with SDS, and its SPRUNG. I have always been happy with my Table, on both concrete, and a @nd Floor Wood Floor Apartment, with a Nice Homemade shelf for Isolation, and a Birch Wood Shelf, I made it all myself. Anyway. I recently talked to Mike at VPI...and the OP hit the Nail on the Head! Its all about cost, and conserving money. Mike told me that my table, the HW19 MK.IV was just about as good as it gets. He also said that at ant time I could always experiment with removing the springs, and putting in the Foam Swimming Noodles, in 3 inch peices, to get a Non Suspended Table, without buying the Special parts they sell that drop in, with same result, for far less money.

Mike also stated that the only reason that they stopped making the HW19 Series of tables was they were far too expensive to keep on making. He said he preferred them to the modern UNSPRUNG VPI Tables, and that if anything at all, would possibly improve my table. it would be to keep it Sprung, as is, but to replace my Tonearm, with a JMW 10.5i...and he would make me up the custom armboard, but for a considerable cost. Im not sure I agree that the JMW Tonearm would be a better choice than my ZETA Silver Wired VandenHul Tonearm. The ZETA was once a world class arm, and by many standards, still is. So, without getting to hear the JMW 10.5i Arm on my Table, I really couldn't fairly say, but Im just telling you how the long conversation went with Mike regarding the HW19 Series of Tables, and I called him to ask this in particular. Reason is, is that I have listened to the Airies, Scout, Scout Master, etc....and have not found any of them to make me feel like WOW...that I felt, and still feel, with my VPI HW19 MK.IV...I love this table, And have been fully pleased with each upgrade, from the HW19 Jr. when I started, in 1986, then went to the Mk.II...Mk.III, and finally into the MK.IV with all the best updates, the better platter, and even went with the SDS, from the Power Line Conditioner. Had to jump in here, as this was a recent discussion I had with Mike, that lasted quite some time, and he stated that they just could not afford to keep on making the HW19 Series of Tables. ray

I rest my case.

Riqe.

Well I live in an apartment building in NYC with a concrete floor and I use an Arcici Lead Balloon stand filled with lead shot. I have a 1" think piece of felt on top and then a 1" piece of acrylic on top of the felt.

My tonearm is the SME V (ca 1987) and I use Grado Cartridges and the SAMA motor.

IMHO the sorbothane suspension is far better than the sprung suspension. The bass goes far deeper and the imaging is higher and deeper.

That's my experience.

I've switched back for a while when I changed out my speakers and amplifiers and ended up with the Sorbothane pucks again.

I still have my VPI Sorbothane pucks, but wont be using them. I really prefer my HW19 MK.IV with Sprung Suspension. I really couldn't ask for more bass. VPI produces wonderful bass as is, HW19's were famous for that. And my ZETA Tonearm was well known for it bass reproduction. Also cartridges come into play, as well as speakers, etc...ALON has incredible Bass, not exagerrated, just very deeep and tight. I have read posts in here, where guys told about excessive supports under their turntables, with concrete floors, using slabs of marble, plus other layers of dense naterial, and some felt, and they were advised by other members that it was overkill, and would hamper performance, I dont understand this, but it can be found either here, or in the Vinyl Engine. It may be overdoing it, with a concrete floor. Ray
