I have a Cambridge 540a V2 that I bought from a member here used for a second system. This thing shocked me. If you try one of these latest V2 integrateds from Cambridge I cant imagine any disappointments. The Totems DO LIKE POWER, and I have not used them with this amp. You my try to pony up for the 640a v2 if possible. I use the preamp out for a sub (sometime a pair) so bass may be hard for me to judge off hand. But ribbon tweeters dont lie, and I have heard worse from more expensive amps. Pretty darn good for music on the cheap.
