I am about to purchase a HK 325 off ebay directly from HK. It is a refurb with a full warranty. I am a perfectionist and am wondering if this thing will look like junk or how bad the scratches will be. Also, I plan on hooking this up to a ventriloquist VT-12 with STF-2 sub. The 525 is not much more off ebay and am wondering if it would be a worthwhile upgrade?
