i'm i going nuts or does the upgrade bug really got me
have a denon 4310ci 2yrs ago---now i saw a 4810ci open box for the same discount price i got my new 4310-- i just wondering why i'm drooling over the open box rather than what i have it's killing me but is it worth the price of getting 4810 and dicounting 4310 that i don't want to sell don't know how to justify this
