I've narrowed it down to the Denon 2803 and either the HK 325 or 525. If I buy an HK, it will likely be refurbished. The only negative I've heard on the HK is the fan, but I've only heard that about the 525, not the 325. Is it also an issue on the 325? Any input on these? I'm in an apartment now, but will be moving in 6 months and would like a receiver that I can use for years to come. This is also about as expensive as I can go, so feel free to mention any good values I may be overlooking. Thanks for the help.
