I all ready had added mass with the 103R (black top plate on the tonearm head). It didn't even touch the sound quality issue I hear with it. Yes, the bass got tighter, ut the mids on up are just not what the Quatros are capable of.
There are no super "serious" issues with my set-up, except the 103r cartridge seems much less "open" sounding in general than the AC-2. I don't think that the equipment will allow even a 100% exact set-up on a 103r to match the AC2 in midrange detail.
But the reviews are 30:1 that says the 103r is a great deal on most speakers, so I took a gamble that I could fake it till I make it on the set-up. No, not 100% extraction of performance, but 80% or so. Nope, didn't do it. Some is imdeed the 103r, and some is indeed my tonearm.
I've mixeda and matched equipment for 30 years, and I've never seen a so-so product eclipse a better one unless the match was simply so gross as to not be worth doing. The 103R with a 25G weight, large paddle, max mass in the counter balancer, and 2.2 grams tracking force isnt miles away from where the 104r needs to be. Exact, no. Terrible, no. My problem was how good the AC-2 is, and I never knew it. My bad.
The compliance measurement is interesting as it doesn't seem to be very linear with frequency or how would you get..."It's more like 15 for the AC2 vs. 9 for the 103R. The 103D works out to 21.6 on an apples to apples basis." I'm sure you meabt 1.66 or so, right? or is it that gossly non lineaer? Something is amiss?
Any way you slice it, the AC-2 is still really good sounding on a SME type III at 2.0 grams. The stylus rack angle (what people thing VTA is,usually around 16-20 degrees, but it isn't) is set to 92 degrees, or close to it "playing" it by ear.
But, I do agree that the 103r is out for all the reasons I "hear" and you "measure". So, I took what everyone said, and went where no one said to go;

This cartridge is smack in the sweet spot for my SME series III tonearm, and price range. Has anyone used this cartridge, and subjectively what was the general sound? Forward, bright, soft, ETC? The two reviews I've read are fovarable. Renmember, I looked at MC designs because the MM amd MI designs were sort of left behind a little more than MC for various reasons, mostly emotional)and some mechanical.
I bough the Quatros for the same reason I tried the 103r, sounding good isn't always throwing money at the problem. A decent design doesn't have to cost a lot. And, a MC isn't always better than a good MM or MI design. The soundsmith seems to be a well done moving iron design that falls right into the best my tonearm can offer. I think, on paper, you all would agree with this decision so far? So you all nudged me in the right direction, but I never really heard what product was in that direction. Still haven't.
So, I was hoping that a voice would have enunciated that this somewhatt rare cartridge exists. I admit, I never heard of it till a friend suggested a GRADO on steroids! It is essentially a GRADO type design basis, and one that seems historically good.
Is the ebony that much better than the AIDA?
Best, to all that have chimed in.
