Hi all, just to correct certain things, the high frequencies were, as Rick noted, severely rolled-off. I don't believe this was due to the idler mechanism (which flipped and flopped like a drunken sailor as the mechanism simply didn't fit this particular Lenco, coming from another [I had assumed these were all drop-in replacements and until the Shootout, considering how good it was anyway, I never noticed]), but instead more a cable issue. The Clearaudio's (my favourite cartridge of all time, and according to Rick I should never even consider selling it, so an unexpected benefit of this Shootout as well) accompanying graph shows it drops off at 14K, but since most men over 30 have roll-offs at about 13K, this shouldn't make much of a difference. The highs did improve, it seemed to both of us, when I swapped to the JMW, but the cable I made for the JMW was a BIG improvement over the cable I had to concoct for the SME, as well, being direct from the RCAs at one end to the Neutriks at the other. And perhaps switching to Mogamis, as I was considering, or something other than "warm-sounding" Cardas cable, would have made even more of a difference.
Anyway, I think this high-frequency roll-off did much too much to colour the outcome, had they been there, then, in terms of neutrality, the contest would have been much closer. But, the Lenco produced, as-was, only the lowest bass to the lower highs, and so sounded much "warmer" than it should have. So let's not make too much of this warmth and musicality issue (at least for now): in terms of absolute information-retrieval, i.e. raw detail, the two 'tables were actually very close within the frequency range the Lenco did reproduce; and in terms of "ordinary" overall dynamics (I mean apart from the "jumping out" percusssion/palpability factor of the Lenco) the two were actually quite close again. It wasn't a night-and-day slaughter of the SME by the Lenco in this respect, more a matter of degree (significant degree, but still degree). I was frankly surprised by how dynamic and exciting the SME really was. I was also frankly surprised by how deep and powerful the bass was. From the lowest bass through the midrange through to the lower high frequencies, the two 'tables were, in overall audiophile terms (detail, imaging, placement, dynamics, etc.), quite close. So, yes, the Lenco IS more involving, more exciting, and so forth, but don't assume it is far behind the SME 30 in terms of information-extraction (we had to switch back and forth, back and forth, in order to hear what each 'table was picking up and how they presented it, in order to hear what each was doing and judge which was correct, they were so close), this was mostly due to the missing high frequencies which, being simply not present on the Lenco, meant the SME simply picked up some detail, and fleshed-out/brought forward other detail, up here which the Lenco did not. Who knows what the JMW/Concerto would have done, and with better cable?
On the other hand, the SME 30 was powerful, dynamic, with deep controlled bass, in these areas quite close to the Lenco (and in the matter of bass, at least with the SME IV/Concerto combo, its equal, superiority was recording-dependent according to my ears), and not what I was expecting from the reviews I read and the auditioning I did of a SME 20. The Lenco furthered these dynamics somewhat, and added superior timing to my ears. The Concerto is considered extremely musical according to the reviews, and according to my ears is simply the best I have ever heard in this respect, and extraordinary in terms of detail, dynamics, and all the rest. I LOVE it. Perhaps the Concerto was giving the Lenco a further advantage in terms of musicality as well. Maybe switching the Concerto to the SME would have brought the SME some needed PRaT and gestalt, and switching the Benz LP to the Lenco would have brought the Lenco further neutrality, thus bringing the two 'tables closer together in terms of musicality - and neutrality - as well.
Anyway, both these 'tables were superb, the experience was amazing, and I thank Rick again for his time and hospitality. For those who are price-conscious, I suggest you don't get too upset the Lenco is SO cheap, the REAL reason idlers stopped being manufactured is that they were simply too expensive to manufacture (they switched to belt-drive because this was cheap and easy to manufacture). The companies - like Lenco - which produced these at the time were HUGE (LP was king and EVERYONE had an LP spinner), with huge R & D resources, and all was manufactured in-house. How much would it cost to design and produce a Lenco from scratch today? So yes, the Lenco can be picked up for $200 today, but that's used, on eBay, today, and even this price has more to do with perception (so-so) than reality (incredible).
Anyway, have fun all, back to my Concerto!!
