Tonearm tweak -- question for Marco
Hey Marco,
From what others have told me here, you are the go-to Denon DL-103 guru, right? If yes, I have a question for you -- have you heard about this 103 tweak, and have you maybe tried it, and what do you think?

Is it worth the trouble?
Thanks and cheers!
Alex

Had that idea - YEARS AGO! Was always going to employ it if ever I got round to making a uni-pivot.
Given up on that now and looking a linear air bearing.

You could always try making an air bearing unipivot!
And yes, it could be done. It's something I pondered over.
It is impossible for anything digital to sound analogue, because it isn't analogue!

Sorry to lay that on you. A number of sources scattered around the net seem to concur with that esoteric tweak. Would be great if a reputable source such as yourself could issue a final verdict (and I know you're gonna do it with such aplomb!)Wow - I'll need to take a holiday to read the length of that article!

A ball and socket unipivot bearing. The arm carrying the socket and the arm stem has the ball (a hemisphere would be adequate). Air being pumped through the stem to the ball, which would have mulitple fine drillings to distribute air around the ball surface, providing a thin 'cushion' within the socket. Much as is done longitudinally with an air bearing linear tracker.

You're not a man of little intelligence, Geoff, so do not fancy a go at a linear air bearing? Arm tube resonance and lossy bearings are bypassed in one fell swoop.
Always admired John Bicht's approach to design. Some moan about the look of the Mission 774 (which he designed, of course). But it's a case of form following function. It's a simple, effective, design. What reason to tart it up? And it's not to say that JB couldn't combine both functionality & form equally into a design. His Versa Dynamics Model 1.0 turntable, and matching stand, clearly shows that:
Looking at this again got me inspired with regards an air bearing design. Have some 1" bar and a mount for it coming. Wondering how the bore in the cartridge platform for the delivery of air should be determined.

Thought about it. Linear arms come with their own set of issues to surmount.

Aye... Life's a compromise.
