For sale, my DSP6ks - upgraded from D6000s, and then to 96/24. 7 segment displays.
Had a full capacitor service about 6-7 years ago by Chris Coaster (all electrolytics replaced). More recently have had replacement black tweeters and new mid range units.
In full working order and reasonable cosmetic condition (with a few retouched chips in the lacquer).
No packaging unfortunately, so buyer collects or delivery negotiable a reasonable distance from Ipswich.
Reason for sale: have gone back to Quad Electrostatics, at least for a while!
Please PM if interested.
