Hello everyone. I just bought a Marantz SR7000 from ebay to power my B&W 601s (upgraded from an old Onkyo TX-DS575x). I wanted to get a Rotel RSX-1056, but money changed, so I had to go with something under $700. I listened to a Marantz SR7000 with my speakers and found them to sound really close to the Rotel I wanted. $1300 vs $300... so I went with the Marantz SR7000. Absolutely happy with the sound, but I'm wondering if I should upgrade to the newer SR7400 because of the following reasons: 7.1 Surround & Heat - I only have fronts and center right now, and I don't intend on going 7.1 surround. But I also here that these 7.1 receivers from Marantz heat up quite a bit. My audio rack is enclosed with glass, so I'm thinking this will cause a problem. Comments? 192/24 vs 96/24 - I don't have a SACD or DVD-A player, so does it even matter to me? I do want movies in DTS, but does that apply? I do plan on buying a Pioneer Elite DV-45A (which does do SACD and DVD-A, but that won't happen for another year), but for now, should I be concern with 192/24? Bass Management / Frequency Crossover - This is the one thing that I definitely don't like about the SR7000. Right now, my whole frequency range is being handled by my B&W 601s. That's fine, but I'm getting my sub this March (birthday) and the SR7000 only has a crossover of 100Hz. I don't want to have my 601s only handling from 100Hz up. I would prefer to have it down in a lower range like 70-80Hz. The newer SR7400 has the option for a 80Hz crossover frequency, so that sounds like something I'd want with a sub. For those with the Marantz receiver before the SR7400, any way around this (.. aside from wiring to the sub and then out to the speakers)? Thank you in advance for all the responses.
