I'm probably upgrading from a LX102 to a LX701. I spent 250 on the LX102 a year or so ago (Display model Best Buy), and I just spent 700 on the LX701 (display model Best Buy). \n\nI can hear an improvement. It sounds like there's more space between the sounds. More presence. Separation.\n\nLX701 seems superior to my other receiver as well, the old 94-TXH, but I haven't tested them side by side. \n\nI'm disappointed that the 701 only has one crossover. I was under the impression that MCACC pro gave each channel its own crossover. I have SVS Ultras across the front, and DT 600s for my height channel and surround channel. I want to run 60hz and 150hz, but instead I'm running the crossover at 80 hz for everything. SB 2000s seem fine. The DT 600s seem fine. \n\nI might return the LX 701 though. It was 700 bucks. I spent 800 on a nice laptop this year. I spent almost 700 bucks on my last computer retrofit. I could buy a set tires for 700 bucks. I could build a garage door for 700 bucks. I know some receivers can cost a whole lot more, but it seems like a lot to pay for an incremental improvement.\n\nI'm going to listen to it all weekend and then switch back to the LX102 to see if I can really hear the difference, or if I'm just fooling myself. \n\nAre the 701, 801, and 901 prone to breaking? Or are they reliable?
