Tone arm length

I have heard, and liked that table/arm combination.  This is a well behaved combination that does a good job of damping resonant energy from the cartridge tracking the groove (as evidenced by how well it damps large, sharp impulses such as ticks and pops; they are less obvious than is the case with many other table/arm combinations).  For some listeners, that kind of behavior is considered "dead" sounding, so taste and system synergy issues matter when it comes to whether this is a very good combination.  A local dealer who usually hates well damped table/arm combinations likes this combination, so it is not extreme in this respect.

Others have discussed the various tradeoffs of longer and shorter arms so I will only add two more points--the longer arm will mean less variation in vertical tracking angle/stylus rake angle when changing records of different thickness.  I don't fiddle with VTA/SRA when changing records, but, I do know from experience that even small changes do affect the sound, so in this respect the longer arm is better.  The longer arm also means a smaller offset angle of the headshell and correspondingly less skating force.  Because the skating force is not zero, antiskating is still required, but, less anti-skating is required and so issues with skating/antiskating is reduced a little.  With newer materials and technology, the rigidity/damping behavior of longer arms has become less of an issue than in the past.  Still, there are many designers who think it is such a high priority that they favor the shorter arm lengths.  I've heard enough good examples of both lengths used in arms from the same manufacturer and I don't think it makes that much difference.

@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

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.
