From 1994 thru 2010, KAB produced a line of modified Technics SL1200's designed and marketed to appeal to audiophiles. Though Technics left the turntable business in 2010, they returned in 2016, with 4 new turntables aimed at the audiophile markets. In 2019, Technics introduced 2 more models: the DJ SL-1200MK7 and this one, the SL-1500C. With six new turntables ranging in price from $1000 to $20,000 Technics is poised to re-establish themselves as major analog players once again.

The KAB Special Edition version of the Technics SL-1500C is especially customized for discerning audiophiles. Those familiar with our work will appreciate these additions. We rewire the tonearm with our Superflex litz copper wiring and add a latex wand liner for added resonance damping. We then add our new TD-1000 fluid damping system which further elevates the tonearm performance. The turntable includes our RC-1200 record clamp and a set of our best SpiralAir all Litz coaxial cables. Lastly, we perform a full pretest QC inspection. Total value of these additions exceeds $518.00

   The motor drive system is rock solid and incredibly accurate. It is an optimally damped, non-cogging direct drive system using a 3 phase 12 pole motor with zero crossing drive for extremely quiet rotation, and a self validating frequency generator right on the platter. As the integral platter magnet rotates past the frequency generator coil, a sine wave is produced representing the exact movement of the platter. This ensures tightly controlled rotation reflected by the amazingly low wow and flutter spec of 0.025% . The spindle bearing , anchored to the cast aluminum base, is a massive 0.280" polished stainless steel shaft closely machined through a long bronze bearing.

This servo drive system responds "just in time" to both static and dynamic stylus drag. It follows strong amplitudes so well that there are no audible changes in speed. The pitch of a loud crescendo stays constant as it fades away. The same cannot be said of many belt drive systems. This sort of sophisticated circuitry can be expensive to develop. But the best way to think about it is that it emulates a belt drive 'table with a very heavy platter.
And remember, the reason rumble is so low in the 1500C is precisely because of four things.
1. Rotation occurs at exact platter speed.
2. The power to the motor is infinitely controllable, and is very very low in normal use.
3. The power is applied at the most rigid part of the platter system: the spindle.
4. Unlike a belt drive system that tugs on the spindle bearing, direct drive systems have equal forces acting on the bearing resulting in longer life and much quieter bearing noise.

   The platter is itself a non-resonant 4 Lb affair. Made from cast aluminum, precision machined, and damped with hard rubber on the bottom . The top mat is 8 Oz. alone and is properly shaped to accept 45 rpm singles as well. 45's are thicker in the middle then on the groove surfaces and flat platter mats cannot support them properly.

This tonearm is one of the great examples of the Gimbal Bearing system, the rotational center of which is precisely defined at one point. Designed at the height of the first audiophile revolution in the late '70's. When the demands were 3/4 gram tracking forces and the requirement to trace groove modulations to 45 Khz (remember CD-4?) The 1500C tonearm is a low - medium mass arm with precision bearings , polished to a finish of ± 0.5 microns, featuring 0.007 gram friction. The arm base utilizes a precision machined brass shaft that fits into a precisely located shaft casted into in the base. The base is spring loaded and moves smoothly up and down. This produces a high precision VTA adjustment. A locking lever keeps the base locked tight after adjustment. The solid brass counterweight is calibrated in grams, properly decoupled and has a nice solid feel to it. Adjustments are quick and reliable. Ditto for Anti-Skate which uses the progressive spring tension method. Easy to adjust, even when the record is playing.
One last thing, those audiophile pressings we so cherish? well many of them are cut on systems using the Technics SP-02 lathe platter drive system. How about that? You can search google to see who uses it. It's nice to know you can have a player that knowingly has something in common with the master disc!

   This should be your turntable if:

  • You are sensitive to pitch variation. Especially in long fades.
  • You appreciate the benefits of Litz wiring and fluid damping.
  • You crave the kind of rock solid stability that digital offers, but with the musicality of vinyl.
  • You need a top flight turntable with a built in high quality phono preamp.
  • You need a top flight turntable that has auto lift at the end of play.

This really should be your last turntable!

   Spec's can tell an awful lot. It's a shame so many Hi End companies have chosen to withhold this vital performance info. The Hi End magazines too should be ashamed for not testing the turntables they "review".

   The Frequency Generator Servo Control on the SL-1500C produces a sine wave, allowing a tightly controlled rotation with wow and flutter of 0.025%. Unlike many belt drive systems, it is completely immune to both static and dynamic stylus drag.

   The Tonearm bearings , polished to a finish of ± 0.5 microns, feature very low friction of 0.007 grams and the turntable body is a 3 section constrained layer non resonant affair. The Cast 4 Lb Platter system is damped both underneath and by the 0.5 Lb top mat.

For the tweakers, the KAB SpiralAir interconnect cable contributes 110 pF and the wire in the turntable and tonearm wand contribute 10 pF for 120pF total capacitance. .


GREAT FEATURES
  • 1 Year Warranty
  • Hinged Dust Cover
  • 33-45-78 RPM
  • Auto-Lift at end of play
  • Phono Preamp Built in
  • KAB TD-1000 Fluid Damping
  • KAB SuperFlex Litz copper Tonearm Wiring
  • KAB SpiralAir all Litz coaxial cables
  • Very Low Bearing Friction
  • KAB RC-1200 Record Clamp
  • Leveling Feet

   The really great features to take note of with the SL-1500C are, I believe, the rotational accuracy, tonearm precision and Audiophile features like Litz wiring and fluid damping

   When a record is playing, the tonearm should be level and parallel to the record, not angled down or up. The adjustable tonearm height in the SL-1500C lets you optimize this setting. It is especially useful when using cartridges of different heights.

   Another neat feature is the auto-lift at end of play. This is delayed approximately 12-20 seconds. Presumably to give you time to lift the arm yourself, or to be sure you don't miss anything that may be recorded in the leadout grooves.

Lastly, the 1500C includes a very nice built in phono preamp and comes with the Ortofon 2M Red pre mounted and aligned on their best headshell. Lastly, we include our RC-1200 record clamp.
