Logic DM 101

I've owned one of these for around twenty years now.
solid build & Fairly easy to setup-adjustable sub-chassis/suspension from above.
Very satisfying sound, superb, open,midband & info retreival. Works well a variety of arms; Syrinx, RB-300 mission 774, & SME IV. Although make sure the springs & grommets are in good condition before you consider a heavy arm.
version; mkII with central coil spring & Delta electronic psu.
My only criticism is a slight swaying of the sub-chassis with warped 12-inch 45's
Came at a time when hi-fi reviewers where obsessed the lp-12.
Manufactured between 1981-1985.

I use one of the early ones with the centre spring and a Logic Datum 11 tone arm. What can I say? it makes a lovely sound and is a real pleasure to listen to.

A PT on steroids. Does everything in a neutral manner, but with real slam in the bass. Hits all the right spots and so easy to adjust the suspension. Built to last and an easy deck to renovate. Just don't try a DC motor as it doesn't take kindly to them.

I bought a Logic DM101 mk 1 in 1982, fitted with a Mission 774 arm, after comparing it in the shop to an LP12 with the same arm. Unfortunately the cartridges in the shop were different, a Koetsu Rosewood on the LP12 and a Mission (773?) on the Logic. Anyhow, my impression was that the differences were small, but that bass reproduction was better on the Logic. At that time I was using a Hitachi PS-48, direct drive turntable, fitted with a Shure V15 IV cartridge. I transfered the cartridge, and as soon as I started playing the first record, I noticed that the main problem with the Hitachi was remedied, the Logic is absolutely insensitive to vibrations and acoustical feedback. It is also an extremely musical player without any trace of tonal coloring. I still use it more or less daily. In the end of the eighties i fitted the Logic/Mission combination with a Decca London. This set up could create some very good results indeed, but it was unfortunately not consistent, so i changed to a Shure V15 V a few years later. This I find is the perfect match for the TT and arm, and fortunately I bought a few spare needles with the cartridge, so I can keep listening for many years to come. The Decca cartridge performs much more consistent in My AR EB101 TT, by the way. I guess the higher mass of the AR arm is a better match for the Decca.
For the moment my equipment beside the Logic consists of a Nad C 165 BEE preamp, a Yamaha TX-950 tuner, Pioneer BDP-LX55 CD-player and DLNA streamer (well, it's actually a blueray device but designed for excellent audio reproduction). The signal from the NAD is fed to a Behringer DEQ2496, who turns the signal digital and equalizes it (correcting room effects and marrying speakers and sub-woofers) before passing it on to two Hypex PSC2.400d power amps (capable of 2x200W in 8 ohms each) who drive my Quad ESL-63 supported by my own dipole sub-woofers. Filtering is done by the Hypex electronics, 4th grade Butterworth crossing over at 125 Hz. Since I finished the sub-woofers I almost entirely play vinyl, switching to the tuner only for needle care ;-). Before I got the sub-woofers I mainly listened to classical music, but now I'm re-experiencing my collection of 70ies and early 80ies rock music. The TT performs equally good on classical, jazz and rock when it gets the right support from the rest of the equipment. It is also very dependent, the only maintenance so far is a change of the drive belt some years ago.

The build quality of the Logic makes it virtually indestructible, so if you can get hold of a used one you will easily get it up to original performance just by cleaning, re-lubricating and changing drive belt.
