Eminent Technology ET-2 Tonearm Owners
I have a very early ET2, so early in fact it came with an ET1 manual. Why would I mention this? Because there is a very interesting technique Bruce describes using a second tone arm and cartridge to measure arm resonance. Have any of you folks hea...

Frogman I do remember having an issue with air loss from the manifold due to a cap screw leaking. I don't remember which one it was, I resolved it by using Teflon plumbers tape on the cap screw.Conversations with Bruce T implied that some have had...

C1 if you are really interested in visitors let me know, I would love to hear your Dalis.Frogman the change in sound with changing pressure was fairly subtle prior to the suspension change and since the change is essentially nonexistent.I don't th...

Since no one has responded I will post my thoughts and see if anyone comments.I think of it this way: As the pressure is increased the volume of air used increases and this is dependent on the clearance between the manifold and spindle. At some po... 
NAD T973
"Wow! What a piece! Weighs a ton, always reassuring!"Not to suggest a resemblance but so do boat anchors. 
Processor upgrade from Integra 9.8?
I would check out the NAD T175HD, M15, or the new T187. I think they are considered one of the better prepros for audio quality. 
Tube Preamp, Amp or Int for holographic imaging?
Not sure what cartridge you are using but I would be looking at the turntable / cartridge before I started making changes in the rest of the system.I was recently at a local dealer and listened to his high end system which consisted of some very n...

Can anyone describe the symptoms / downside of over pressure?Initially (recent history as I have had this arm since '85) it seemed that the music dulled a bit above 16 psi.After replacing the spring suspension in my TNT mk 1? with delrin cups and ... 
NAD T973
I have a T973 driving Dali Diva Grand mains in a 7 channel setup. I have used a M15 and a T175HD with it. I am very impressed with this setup. I went from a two channel setup to 5.1 then 7.1 and have recently returned to listening to vinyl using a...

If you want to experiment with really low compliance tightly coupled counterweight you could just wedge something like a tooth pick in the joint to essentially remove the spring from the equation. I think Bruce mentions this somewhere, in any even... 
VPI TNT Bearing question
Yes it is a bit of a crap shoot but you really would not have much invested except time unless you use some super exotic bearing material such as rulon and even then you don't need much of it for a TT bearing.I think making a turntable bearing for... 
VPI TNT Bearing question
Very interesting and thought provoking responses.I am not worried about aluminum threads stripping and suspect you could shear of the top collar of the bearing housing if you apply enough torque (consider the amount of material engaged in the thre...

The ears always rule. Didn't mean to suggest otherwise. If things always worked as physics suggests then this treck would be much easier.

Re I beam complianceI think what Bruce is saying is he is using the decoupling of the balance weights to reduce the effective horizontal mass which allows the use of heavier arm components with their inherent increased stiffness. This seems to imp... 
VPI TNT Bearing question
Thanks for all the responses. My thought was not in finding a MK 5 bearing but in modifying the mount of the bearing I have. There are a couple of options that come to mind but the housing appears to be thick enough to thread and attach like the M...
