Quad 989 vs. SoundLab Millennium 2

I too have questions about these speakers. I am trying to decide to keep my Q63/sub combo or go to the 989s or Soundlabs. Any info would be appreciated.

I recently listened to SL M-1s at Audiokinesis. I feel that these are the most re-creative speakers I have heard. They are more transparent than any other electrostatic I know of. Wolcotts amps were used to good effect, I played the first disk in the Solti Die Walkure reissue. I tell you it was exactly as the stage direction/orchestral layout is depicted in the liner notes. The tonality of the horns and then double basses when Hunding enters, etc., was almost visual in its naturalness. (I did not like the S/S monblocks - warners or something - they sounded like a bad phonostage.) I just ordered a pair....of M1s - amps later if the Pass can't cut it and if the exchequer recovers...Oh yes Duke is a class act....

since then I have gone to an all Pass preamp/phono amp system with Sound Labs u-1 PXs. I use SACD, DVDA, Hires computer feeds, a Don Scott modified Accuphase T100 and a Linn with an Ikeda cartridge and an old linear Yamaha with an Ortofon MC.

The Wolcotts have died and I cannot find any relief at their website. It was glorious while it lasted.

Now I have a Levinson 432 with updated biasing.

What can I do to improve a very very good amplifier that takes balanced inputs.

I'm back!
