As I started this thread, I would like to make the following comments: -
1) Amazing how my really simple question can lead to all sorts of side issues.
2) The following comment from nicholaslb"Clearly, if you have money to burn, then bi-amping with 28B-SST amps will sound better than single-amping with 28B-SST but the difference (on B&W speakers) will be small. And, in the majority of cases, it's better to use a single large amp than two smaller ones. As James T says, you can sometimes get good results using a large amp for the bass drivers and a smaller one for the treble and mid, but that's not something I'd advise you to mess with unless you really know what you're doing!"
If you read my initial thread - then this is just what I was asking.
I am going from B&W 802 to B&W800D and I wanted to get some extra power to drive these difficult speakers - THAT'S ALL ! !
BTW James - as soon as the 28B SST are released - I would appreciate a PM from you so I can arrange to get two.
Thanks
