Sdcambell makes a good point about the softeness of the Adcom amps but depending on the rest of your rig you may feel that this isn't a problem.I sold Adcom for 6 years and found the 5802 to be a great bargain and different,way ahead of the rest of their product.They were designed by nelson Pass of Threshold fame and in a cost to performance ratio kicked butt on many other lines.They tended to be very warm though I resist calling them tube like as many others have.But you may not neeed this much power.I thought they worked great for say Maggie owners who needed high current.They worked great with the matching GFP-750 pre-amp as both were balanced.Together with a good set of XLR interconnect chosen to compliment the rest of the rig it was a hard combo to beat for those with power hungry speakers in a bigger room.The only complaint I had was in terms of build quality though this was more of an issue with the pre-amp than the power amp.It's a big company and my guess was that the reliablity issue came with the number of units sold.But I think that for $1250 or abouts used with a 750 pre for $750 or thereabouts it's worth a try.I would defintely take the 5802 over the 5500 in terms of extra power and sound quality.
