I've almost completely updated my system to current ARC components from an early '80s ARC-based system. Replaced the ARC SP-8 and D90B tubed pre-amp & amp to a tubed LS-17 line stage, PH-5 tubed phono stage, and SS ARC 150.2 amp. I find the ARC 150.2 class D amp matches very well with the Maggie 1.6QRs (which replaced earlier MGIIAs). In addition, I've replaced a damaged Accuphase AC2 mc with the Benz Micro MC20E2L, added a NAD C542 CD player, updated IC to Kimber Hero and PBJ single-ended, and Mogami Gold balanced, and moved component shelving in order to replace 25' of old Monster speaker cable with 8' of PNF Symphony.

Next upgrades will probably be to add a MOSE power supply to the Linn, as well as replacing the old suspension springs.
