Anyone Using A Logic Turntable?


I use a Logic DM101 table with a modded RB300 and Grado Reference cartridge with great results. My understanding is that this table was designed to compete with the Linn but got poor reviews and never went anywhere. I stumbled upon this thing cheap and thought it might be worth a listen. After cleaning the motor, changing the bearing oil and switching the lose crappy springs to more rigid ones (similar to the Linn Trampoline upgrade I suppose) I mounted my arm and cartridge.

The result was just fantastic far better than I had hoped for. It easily surpassed my Rega2 with motor upgrade I was pleased indeed. I've since sold my Rega and actually made a profit on my source!! Imagine that an audio nut who made money at this insanely expensive hobby go figure!!

Seeing how this thing sounds so good and owes me nothing I have no plans to get rid of it. I suspect the motor and power supply is the Logic's weak point and I am planning to get the motor thrust bearing and platter ring clamp upgrade available on ebay soon which should enhance things further.

I've had great results and fun with this table is anyone else using one? What have your experiences been? It's really hard to find info on this thing.

I used to own a DM 101 back in the late 80's. I used a Magnepan Unitrac arm and a Dynavector Ruby with good results.

My recollection is that it is a British made table that came on the market about the same time as the Pink Triangle. The suspension was indeed incredibly soft. It would take like 10 seconds for the platter/sub-chassis to settle down after lowering the arm. I wasn't much of a tweaker back then, so I just lived with the trampoline effect.

I ended up trading it to a guy who already owned one who wanted mine for future use/parts since Logic was pulling out of the US market. I then upgraded to a Goldmund Studietto/T5/Accuphase AC-2. While the Goldmund rig was clearly and definitively superior to the Logic, I still remember my DM-101 fondly.

Good stuff.
I had a DM101, which I sold about two years ago. The trampoline effect was a pain, but I agree it was and still is a pretty good deck. I had an Audio technica AT1100 and Micro Seiki LC80W pick up on it - both had rave reviews in the early 80s.
Ended up buying a mint TD124, which I've now also sold for a Platine Verdier.
The Logic DM101 is my table of choice. In fact, I have two more brand new and in-the-box in the basement for parts/spares.

My Logic is used with Sumeko MMT arm w/ Orsonics headshell and Koetsu Black cartridge.

The local dealer (Al Tucker at Better Sound Concepts, Pittsburgh) who sold these way back when kept advising me against one because he believed them to be too tweaky for my tastes. Instead, he sold me a Sonograph which I ended up trading someone for a Logic straight up about 1 year later. So, I got one as did my good friends Tom & Ed. (OK, they had theirs before me.) Tom uses a Helius arm which has an SME mouting; Ed and I use custom made aluminum SME to standard mounting adapters. Both of them use Shure V15 cartridges though Tom used ot have a Koetsu Black.

All 3 of us still use this as our tables of choice. None of us have changed the springs and, no, the table does not take 10 seconds to "quiet" after dropping the arm.

I believe that the "magic" of my set-up is the all alluminum interface from cantilever through subchassis since the Koetsu black body, Orsonic headshell, MMT arm, mounitng bracket and Logic subchassis are all comprised of aluminum. It is my theroy that the similar metal drains off all extaneous vibrations [noise] to the VERY EFFECTIVE Logic suspension. Oh, the lovely quiet of the record grooves - even with older records bought 2nd hand! Plus, the jump, the dynamics, the beatiful tone...

I never did find any problem with the rumored "tweakiness" of the thing...as long as you don't try to play any 45 RPM records. (Reference Recording made some audiophile grade 45 RPM LPs some time ago. After buying and trying to play one, I stopped.)

The 2 spare tables were given to me by the local dealer after Logic went "belly up".
