Rega upgrades/tweeks

Mikkysix - I have to ask - what is PRaT???

Thanks

Added the Michell Techno Weight to my Rega RB250 Arm
Purchased from Trichord Research

OK - so this was the only purchase to date where I thought I would not see much improvement and was prepared to live with the fact that it may only "look better" than the Rega supplied weight.

I mean - where's the science? - a lump of metal attached to the "non-business-end" of the arm, just hanging there doin nothin except looking cool!

Boy, was I ever surprised...
- I first noticed considerably more details in the low frequencies and significantly deeper - played Genesis - Trick of the Tail
- then the very precise imaging grabbed my attention - instruments appeared much more separated and focussed - played Eine kleine Nachtmusik from Tacet
- then I put on Stevie Wonder's Superstition - WOW! - what a transformation - so full of energy
- So then I tried my James Newton Howard & Friends album and all of the above differences could clearly be heard quite clearly

To sum it up in one word - DYNAMIC! - much more dynamic

Who woulda thunk it! Definitely a worth-while investment!

It did take 2 weeks to arrive - seems it had customs baffled - they even opened the blister pack!

Trichord Research were very good at responding to my questions about when it was sent and even offered to send another unit. - Nice to see good Customer Service for once!

I'm now considering the Michell Techno-arm

Williewonka, I had the same skepticism about Michell's Tecnoweight. It's amazing that a counterweight can do so much. Before you splurge on a Tecno-arm, check out this $5 mod to your RB250:

Mark (Mingles) curse you! I thought I was finsihed with tweeks! 8-)

If I read it correctly the idea is to sit a small bar across the pivot point with two out-rigger weights to resist only the lateral movement created by the groove pushing on the stylus - make a lot of sense.

The ole grey matter is now working overtime with a removable design that can simply be dropped onto the the arm.

Seems there are some key points to consider
1. the distance the weights are suspended from the pivot point - there has got to be an optimal distance?
2. keeping the C.O.G. on the same plane as the stylus - I think this is a key reason why the Techno weight works so well, since the weight was no heavier than my Rega Weight and no wider
3. ensuring the weights are centered i.e. precisely balanced
4. do not allow the weight to swing freely

I'm currently working on a 2 1/4" thick MDF plinth, so it will have to wait.
But the winters in Canada are long and dark, so I should have some time - between skiing that is!

Thanks for the pointer.

Hi Williewonka,

Pace, Rhythm and Timing. Lot of folks question it's existence and validity. I will say that I think of it in terms of how 'involving' the presentation is, which is purely subjective, and can be measured from the size of my grin. From what I've understood about Regas, this is what these tables are designed to excel at. Their light mass construction is supposed to help enhance the liveliness and attack of the music. Rather than absorbing and sinking vibration like a heavy plinth design, these tables are supposed to shed that vibration quickly.

Regards,
