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

Elliot, smart man. Measure twice cut once. My contractor had that stenciled on his truck.
The Pioneer arm is in the same ball park as the JVC arm which I like better but I have to admit my preference is instinctive. Most tonearms with removable head shells have higher effective masses. That relatively heavy mechanism is right at the end of the tonearm and adds directly to the effective mass. If you want to use a high compliance cartridge 20u/mN or higher you have to use an arm with a fixed head shell or a novel system like the Kuzma 4 point 9. Look at the Pro-Ject Evo 12. That is a relatively light 12 inch arm. The SME V 12 is another but that one is very pricey. A used Kuzma Stogi Ref 313 might fit in nicely.

lewm,

I'm handy, I could fix the rubber of any 7045 I buy. Does the flexibility of the rubber make much difference?

Being careful, before choosing the rear arm for Mono,

I will wait to see the exact location of the existing rear hole on the dual arm tt I bought.

We don't know what arm it was drilled for.

UA-7045 is effective 9-5/8"

I am warming up to the Grado ME+ Mono Cartridge, waiting for Grado to tell me the compliance. It's elliptical, not Shibata like the Ortofon, but the Grado internals sound advantageous, and help suppress Resonance.

while tempting, I am not going for the tt with tt61 and pioneer arm. I'm gonna get the stereo 7082 arm and cartridge/stylus resonled first.

Then measure the distance: spindle to the rear hole of the tt I bought when it gets here. 7045 arm is effective 9-5/8".

Mono Cartridge: Depending on chosen arm, I might buy the Ortofon 2 M SE with Shibata Stylus, output 3mV, but, I prefer the higher output 5.0 mV of the Grado ME+ (only comes elliptical).

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

Main longer arm, 7082 11-1/8" effective length.

Stereo Only. use it's Z1s cartridge, upgrade Stylus to SAS/Boron.

light 1.5g tracking, J1 cartridge is high 5 mV output
........................................

Rear, to be purchased +/- 9" arm (not get a UA-7045)

Stereo and Mono use

select an arm specifically for medium/high compliance STEREO cartridge
and a medium/high compliance MONO cartridge.

That way I can continue to use both my Shures: 97xe elliptical and V15VxMR microline. Both light tracking, high output, use or not use Dynamic Stabilizer Brush (brush also grabs dust, reduces static). Both light tracking/high output

97xe: get an SAS/Boron Stylus from Jico

Rear +/- 9" medium/high compliance arm

Dear Mijo, You wrote, "Even a cheap modern turntable transfers very little energy to the surrounding environment. A good turntable with a good record hold down system that dampens the record with a stiff multi bearing arm set up correctly will transfer virtually nothing."
Where did I say that "turntables" transfer energy into the "environment"?  What I inferred was that cartridges are microphonic; they all give off some audible noises as they decode the musical signal.  Now it's my turn to be incredulous, if you say you've never heard such a phenomenon. But here is where I will confess to being guilty of a common audiophile sin:  To me, that sound energy coming directly from cartridges is obvious, and to me it has always been obvious that dust covers add a coloration that I do not like.  So, I put these two facts together and ascribed causality.  I hate when others do that, so I plead mea culpa for having done it in this case.  I've never proven that the coloration imparted by dust covers is per se due to cartridge microphony. Suffice to say that for me dust covers add a coloration that MIGHT be due to trapping the acoustic energy put out by a cartridge during play.  Thus I never ever use a dust cover.  I think you would find that most serious vinylistas don't use them either.  I wonder how many others on this thread use dust covers.


Elliott:  If someone can tell me how to post photos here, I will show you how I re-enforced and increased the mass of the Victor QL-10 plinth that came with my TT101. All done with aluminum custom fitted.
