Update: I'll knock $100 off to sell this locally in the SF Bay Area

The legendary, very-hard-to-find mixer now reincarnated as the Speck Lilo. Some of the finest EQ you can get, amazing saturation on overdriving channels, simply just an amazing sound.

Mine is working well, but being sold as-is due to age and complex nature of any analog mixer. Speck offers a complete refurbish for $1350 (worth it).

BTW, if you're a fan of Basic Channel / Moritz von Oswald / Maurizio, this is the mixer that defined his sound.

The mixer.

I don't think there's a mixer on the market that matches the sound quality and feature set of the SSM for nearly this price. Even with the refurbish you're still cheaper with the Lilo. You can use this for synths, drum machines, or as I did — as a summing mixer for your DAW, getting the channels out of the box, into an amazing board, EQ'ed (with 8 effects sends), and then back in.

Condition

Some knobs and sliders have noise/crackle when moving from dust — as is common with mixers this old. It is not really a problem for most usage, but you can either use DeOxit or send it in for refurb if it bothers you. All knobs and parts are present, including fully-working external power supply. No knobs, caps, or sliders are missing — and I have an extra of each included with the sale. The bottom right rack corner of the rackmount is a bit rough (see photos) but mounts fine. All high quality mixers like this require maintenance. I had to send my Neve 8816 in for repair 3x. That's just part of the deal when dealing with discrete analog circuitry.
