Tone arm length

@mikelavigne Thank you for the thoughtful insight. That makes a lot of sense.

What little I know about this, the benefits of the longer arm (#3) apply mostly to the inner grooves.   

@yoyoyaya thanks for the feedback. The professional power supply is only compatible with concept and performance TT according to their website.

im curious how the PS improves sound if TT speed is optically controlled and the motor is decoupled from the platter?

Go Big or Go Home

Ha! The price difference is less than $500 so why not. 

The only negative the dealer pointed out was the additional over hang when not in use. He said most leave with the 12". 

The Smart Power 24v will have to wait though.

@yoyoyaya thank you

@elliottbnewcombjr Thanks for the extra info - I’ve checked out your 3 arm TT before - very cool.

I'm going with the 12" and the dealer will set it up for me.

@billstevenson

Interesting and thank you for sharing the insight. By any chance did you ever hop on the ferry over to Victoria and if so, did you visit Sound Hounds?   

Interested in selling one of those scopes???

btw I've bought the TT with the 12" so that's that.

@billstevenson

Nice! Thanks Bill, will do.

I lived on the island from 1971 to 1992. My first visit to sound hounds was around 1980 .It was a bit dingy - geeky back then but super cool. Had all the MAC stuff including their first CD player. Looks like it's had a refresh but still in business AND in the same location which is amazing.

Chiming in just to say I’ve been following the thread and learning, thank you.

I’m about to set up my 12” on as I have a new cart coming. 
 

I have some Wally Tools arriving soon.

@rauliruegas

I’m not sure what this means? I can see not really " learning "

@dwette @mikelavigne

To Mike’s point #3 (2nd post). I ended up with a MSL Signature Platinum analyzed by JR at Wally Tools and installed the cart to those parameters which included a custom shim to correct for SRA as well as data to adjust azimuth and stylus zenith error.

So I’m pretty confident I ended up maximizing the benefits of the 12" with a much better than average cart alignment.

In any case, I’m done and happy. Stunning amount of never-before-heard detail yet very musical, relaxing presentation.

Cheers all.

@mikelavigne exactly - thank you Mike. Have an awesome weekend!
