Liz, My tests with Monsters are that HTS2000 does indeed slightly improve sound, as Robt Harley from AS claims, but higher up units actually degrade the sound for audio only systems. My test was with HTS3500 with stage 3 filtering and was worse sounding than HTS2000, fine detail was removed to my hearing, softer more opaque sound that was less dynamic. I personally would not connect two cheap line conditioners together in series, would almost certainly result in degraded sound.
Monst5000 power thingy AFTER Adcom ACE:
Goa a Monster powerline5000 conditioner and was playing around and discovered that the SOUND was really way better with the Monster plugged into the Adcom (the Adcom plugged in the wall, the monster in the Adcom and all else in the Monster. SWEET sounds!!! much better than Monster alone! The only flaw is the BASS sems a bit softer.... (the Amp [a Forte' 4] plugged in the Adcom too, leaves the bass more intact) But I live in an apartment and that is a small price to pay for such glorious sound. Smooth and totally grain free. Clarity! The only other complaint I have is the AC sockets in the back of the Monster are typical $0.29 bargin basement trash. AC plugs almost fall out if they are a bit heavy. I plan on replacing them! Anyone with any comments on my ? "Rube Goldberg" setup??
