I've been living with the Monolith by Monoprice M8125x 8x100 for about a month now. I picked it up from the Ebay Monoprice store when they had a sale going on at $1,200. Ebay also gave me another $60 off! I had it in the cart for a day or so, Monoprice sent me an offer for $1,139.00, too good to turn down. Especially now not even a month later they are $1999. I have it hooked up Via XLR to an Anthem AVM70 with a 5.2.2 system, all new (to me) Polk Reserve and Legend Series. r700 fronts, L400 Center, R100 surrounds, and R900 height speakers, soon adding two Rythmik E15" subwoofer. :0 The Amp is dead silent, even when I turn the processor up all the way (with no content) The Polk LCR are rated at 4ohm, and lower. The Monolith handles them without a sweat! Honestly, I'm surprised at how much headroom I have. The loudest I could bear for a few minutes was -15, normally I'm listening at -35 to -30, sometimes more or less. Anyway, I thought I may want to get the Monolith 200x3 for the front LCR, but now I don't think so, unless I plan on adding more speakers I think I'm pleased. Doesn't get hot, actually doesn't even get warm, honestly, I think the Anthem processor gets warmer, surprised with that as well. Cheers!
