I currently have a Rotel RA-05, Marantz CD6002 and B & W 685's. I went to have a demo and told a couple of porkies, mainly to get a listen of my current set up in the demo room. Sounded good with a couple of tracks, notably The blowers daughter by Damian Rice, getting a little too much bass. Glad it just isnt my room. Swapped the amp then for a Roksan K2. Loads more detail and a better sound but less bass and seemed less interesting that the rotel. I guess it is just what my ears are used to as i heard a bass line in a song that i hadn't heard before. In all this was as you might expect a big step up. We then hooked up the K2 cd player. Now that was a little disappointing. Not much difference between that and the marantz. Is the K2 amp getting too good for my speakers as i dont want to upgrade all at once and why don't the shop staff leave you to get on with a demo. He was 22 and you could tell me taste in demo music, Billy Bragg, Rice, Beatles, Clash bored him rigid.
