Not so sure about this thread! The amplifier in the 6500/7000 is not bad but isn't one of the very best in my opinion. The 5500 amplifier is essentially the same. The pre-amp in the 5000 is actually rather nicer. I am not criticising it - I use a 5500 every day and have a 7000 as well - they are all capable of driving any of the B&O passive speakers well though. CX100s are very nice bookshelf speakers - I have a couple of pairs and like them. I don't regard them as real hi-fi though!
Tim's S80.2s are nice ones - I gave them to him after Windows of the Arcade gave them to me! He has replaced the capacitors which has improved them no end. S120s have slightly extended bass. Very similar size but they have a bass port.
