JFT's Main System

      Pictured here are the Philips SACD 1000 player, Assemblage hybrid tube/FET preamp, Rotel RB-1090 amp, and Magnepan 1.6QR's.   The components are sitting on an Atlantis Reference rack. Also visible under the TV is a Hsu VTF-2 subwoofer.

JFT's MG1.6/QR System

      Here's a view of the DIY speaker stands and the upgrade crossover.   The stands are modeled after a pair I saw in the tweaks section.   The feet are 24" long, 2½" wide oak boards stained to match the floors.   The stock Maggie feet are screwed directly to the boards.   The uprights are 5 foot sections of ½" conduit inserted at the bottom into a PVC plumbing bracket, which is attached to the boards with metal straps.   Each crossover incorporates a North Creek 12ga inductor and a 22uF Auricap.   For the woofer shunt caps I used the stock Solens plus a 3uf Multicap to take the sandwich up to the required 25uF.   There is also a tweeter attenuator bypass switch which bypasses a 1.5 ohm Mills wirewound resistor.   Each crossover is contained in a plastic box attached directly outside of the original crossover space on the speaker.   The tweeter cables are Kimber 4-TC, the woofer cables are MIT-4.   All cables are hidden as much as possible to enhance the WAF factor of the system.
