Hi,
I bought one not too long ago for its tonearm. I never tried it, but I thought I would take it apart for you guys. :)
Anyway, it is interesting in that the suspension consists of six springs horizontally mounted in pairs linked by a grommet in the middle. This creates a simple, but effective, three-point suspension. It is a very clever implementation, not terribly unlike the way the motor is mounted in a Garrard 301. I believe it could be the smartest springy design of the period. It is also a place that allows for tweaking by changing the factory springs with stiffer ones.
The base consists of two pieces of mdf laminated together, and the motor is mounted on it, not on the subchassis, like some springies. This gives a measure of isolation.
Speaking of the subchassis, it is a heavy 10mm aluminum plate that is cut with an SME slot, and configured in such a way that it should balance the typical tonearm well without a need to unduly stretch any of the springs. The best part is that it doesn't rely on a separate armboard, so the coupling there is positive.
The bearing well is also nice for the type turntable. It is remarkably heavy for a turntable in the price range, and construction is good. The spindle is fixed to the subplatter, but nicely finished. The only downside I see is that the steel ball is not captive. The original Thorens TD150 is better in that regard. Still, it is well made.
Both the subplatter and the main platter are finished well, and they fit together with precision. Best of all, the felt donut is attached to the main platter. I always despised those mats that slipped around. This one is a step up in that regard. The platter and subplatter appear to be aluminum, not zinc, and both are clear anodized. I see that as a plus, too.
The motor, like that in other springies, is not to die for. I see it as the best place to tweak the turntable. Mine was so crappy that it showed up in two pieces, although the shipper packaged the turntable very well. I put it back together, and it works, however. I don't see why it couldn't be upgraded, if you owners are so inclined. Still, it isn't as bad as some out there.
Other details are present, like a really hefty powercord for a turntable, a good switch, covers over parts that shouldn't be exposed, a decent lid, etc.
I believe Logic put a lot of thought and money into the turntable for no more than it retailed for back then. That made it a bargain, and probably is why they went out of business.
I own a Linn and a few Thorens springies, but it is my opinion that this old Logic DM 101 may be the pick of the litter.
