Rower,
You didn't add enough mass using one of those headshell plates, to put the 103R in its operating range. In fact you wouldn't want to add at the headshell all the mass necessary to load your light tonearm to the effective mass needed for that cartridge.
>>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.<<
The 103R *is* a great cartridge, period. It's not the only great cartridge, but it's one, and that's apparent on any at least reasonably good speaker. You can't fake its setup, however. Your tonearm is so mismatched to the 103R that you can't get 80% or 60% or even 40% sonic performance the 103R is capable of. The pairing doesn't work for either instrument, regardless of loudspeakers you listen to.
>>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.<<
This is a misunderstanding of the issues. It *is* miles away. Your SME III has an effective mass of just 5 grams. A Denon 103R just begins to sound good in a 12 grams eff mass Rega tonearm, where even there additional mass at the headshell improves the sound. The 103R is commonly used in tonearms having effective mass in the range of 20 - 25 grams. Your arm isn't even close. The Zu103 modification of the 103 adds 5.5g of mass to the 103/103R total mass, reaching 14g. If you add a gram's worth of bolts, putting THAT 15g block in your tonearm will still leave the combination in borderline operating range. In the SME III, the 103R *will* absolutely sound dull, undynamic and have funky bass.
>>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?<<
No, I didn't mean "1.66." The 103/103R have compliance rating of 5 x10-6cm/Dyne at 100 Hz. The AC-2 has a compliance rating of 15 x10-6cm/Dyne at 10 Hz. To reconcile Denon's non-standard 100 Hz rating with Accuphase's standard 10 Hz rating, multiply the Denon spec by 1.8. The 103R normalized compliance spec becomes 9 x10-6cm/Dyne. The higher compliance 103D is normalized to 21.6 x10-6cm/Dyne, which is why you liked the D but not the R.
I have no idea what you mean by "...doesn't seem very linear by frequency..." Again, you have a tonearm with effective mass of just 5 grams. The AC-2 is serviceable but borderline with it. The 103R is wholly mismatched. You haven't listened to an AC-2 vs. 103R comparison. You've listened to a semi-optimal-but-serviceable AC-2/SMEIII pairing compared to a completely non-optimal 103R/SMEIII combination that puts the 103R outside its operating range. I'm only using data to explain sonic results that would have been entirely predictable. None of us in this thread would even suggest you can get good sound out of a 103R with *any* 5 grams effective mass tonearm. This isn't a quality issue about either component. It's a matching issue. That a 103D sounded good in your tonearm is irrelevent to whether a lower compliance 103R will work.

You may or may not like the Soundsmith, but at least you'll be giving it a fair shot by choosing the high compliance option for good matching to your tonearm. Some of us in this thread think you can do much better by not being constrained by your low mass tonearm and its various design compromises that probably seemed like good ideas at the time to SME.
Personally, I would not spend $2,200 on a cartridge for your front-end. Especially not when you can spend just roughly $500 on the excellent Denon DL304 or $1000 on the Denon DLS1, both of which have a normalized compliance rating of about 25 x10-6cm/Dyne, which will work fine in your 5 grams effective mass tonearm.
All that said, the AC-2 is a fine cartridge. I owned both AC-1 and AC-2 back in the 1980s, alongside the Denon 103D. I preferred the 103D overall but the AC cartridges were better in some respects. If you love the AC-2 and are committed to your SME III, send the Accuphase to Soundsmith for a rehab and be happy.
