Tone arm length

@OP There is a 24 volt version of the Professional PSU for use with the Innovation series of turntables. Hi Fi news found that the Professional PSU significantly (measurably) reduced rumble - so it's not just about speed stability. However, the motor itself and the optical control circuit will benefit from a more stable, lower noise supply.  The deck used with the professional PSU has blacker backgrounds, better low level linearity and more articulate bass.

@yoyoyaya thank you

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.

Wanting; Knowing; Hearing: ’different’, ’better’, ’preferred’.

Long Arm was why I joined Audiogon in 2019. I found the longest that I could fit under the dust cover when on.

TT, 12" Tonearm. Who tried and ended up preferring 12" arm?

Asked about, ended up choosing Blackbird 12.5" arm from Russia

Revised 5 Pin Din Version

We usually change more than 1 thing at a time, in my case I changed Plinth/ Spinner/Arms(3)/Cartridge Types/SUT/Alignment Tools/Methods so what can I say except I love the choices/changes I made that wanting a long arm set in motion.

The best thing is the long arm led to a large plinth which led to 2 arms (far more important IMO) (stereo and mono ready to play instantly). In my case I squeezed a 3rd arm on for MC Stereo/MM Stereo/Mono.

After a few years, I realized I am benefitting from more accurately maintained anti-skate outer to inner tracks as well as the benefits of the stylus tip’s position in the grooves due to a longer arc’s geometry.

Imaging absolutely requires proper anti-skate. it’s also the major factor in avoiding uneven wear to your expensive stylus and lp’s grooves. Tracking force wants proper anti-skate, freedom to react to the groove wall info.

I would prefer a removable headshell, as I never hear the long arm benefits thru my alternate cartridges. I compare/enjoy them on my 9" arm. And I don’t hear my ’best’ cartridge on the 9" arm, so comparisons always involve the benefit or lack of extra length.

..............................

12" is not always 12", check the specs, i.e. many are less, i.e. the JVC long arm 7082 is only 11-1/8" effective, whereas their short arm 7045 is 9-5/8" effective. I went for the longest I could find with a design (price of course) I wanted, that was compact enough to ’just fit’ on the arm-board of my large 2 arm plinth.

........................................................

2 arms, one long, both removable headshells is the most flexible setup, that’s what I helped a friend put together, a 2 arm Luxman PD-444 with long and short Micro-Seiki 505 Arms.

Luxman is ’normal’ depth, wider, my JVC PL-2 Plinth is both deeper and wider, I had to have a ’deeper’ glass shelf made, the Luxman would have fit the existing glass top.

my 3 arm TT seen here

@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.
