SP10 MK3 recommendation

I have Reed 3Q 12 inch arm (cocobolo) and used it with Air Tight PC-1 Supreme and now have Lyra Atlas on it. Using both on TW Raven AC-1, I would give an edge to Lyra. Air Tight is a bit cooler, a little bit more delicate, bass is tight, deep. Lyra is more robust, more slam, bigger sounding, a bit more full body. Neither sound harsh, bright or edgy on lesser recording. Air Tight/Reed combination was great on most classical, vocal, chamber, piano music but not as good on rock,pop, large symphonic pieces. Lyra/Reed is really good on just about all kind of music I throw at it. Mine you, Air Tight can definite rock but not with Reed. Air Tight bass was excellent with Graham but I never quite managed to get the same magic on vocal, piano or violin as I did with Reed. In fact overall, I prefer Air Tight on Reed or JWM 10.5i than Graham. However, Graham is a much much better match to Dynavector XV-1s than Reed or JWM 10.5i.
If you stick with Reed, I definitely would go with Lyra. If it is other arms, it really would depends on synergy, I suppose.

Dear Br3098: In general I agree with you. On the length of the wire what you or me could imagine could be only speculation what is a fact is what is happening down there at microscopic level where contamination/polulation happened and remember that almost always in audio less is more.

+++ " (presumably) " ++++, whom knows for sure?

Dear Peterayer: I speak on 10.5" against 12" not 9" that has additional problems.

Btw, could be that an specific cartridge could " performs " ( that you like it more. ) better in a 12" tonearm than in a 10.5" but IMHO mostly because the added 12" colorations and not because any 12" real advantages because IMHO there is not.

Of course if we already own a 12" tonearm we have to believe we are with a self induction that this is the " one " because is the one I have and I paid for it.

Normally when I'm talking on audio subjects I try hard to stay unbiased in anyway but in favor of music home reproduction. I'm not married with any single audio factor/characteristic/parameter and always open to learn and change if necesary.

I make comparisons/evaluations against very precise targets where certainly one of those targets is not " what I like ".

Raul, I'm just saying that in my system the 12" SME V-12 sounded more like real instruments than the 9" arm. I own both and paid for both, so the only thing that matters to me is which one I prefer. "What I like" for me means what sounds more real in my system, to my ears. It's very subjective. If that is not your target, what is? I use live classical music as my reference and frequently hear concerts and then gauge the quality of my system against that reference. Others may aim for numbers and that is fine. I don't know what you mean by "12" colorations."

Dear Peterayer: Your comparison on the V-12 against the V is not exactly: apples against apples. The V12 internal wiring is different to the V as is the tonearm bearing and the arm wand to stay with an almost similar effective mass as the V: 12grs against 11grs.

IMHO the diferences you heard are coming from a different build design, even that looks similar externally, more than the 12" length per se against the 9".

In amedium like the analog LP the tonearm has to deal with the reality of non perfect LP: warps and off center LPs and this is the day by day tonearm works in each single LP through all the LP tracks.
Well, the 12" are in disadvantages against the shorter ones that has a faster response to warps and off center problems, the 12" has slower response for deal with those LP problems and that means higher distortions/colorations.

Maybe your 12" tonearm could be better than your 9" one but IMHO not because its length but because a better design and execution design.
