Met my friend at lunch today for an audition of some equipment. Firstly: The lighter coloured DM604S3 B+W speakers All Arcam: CD192 A90 amp DT81 DAB tuner Not bi-wired. It sounded great. Then we asked for it to be bi-amped and bi-wired with the P90 amp. Oh my word! It sounded awesome in this configuration. Of the CDs we tried in the initial config, the worst quality one sounded sooo much better. Add a stand and £180 of cables and he was away. I am very, very jealous but I am sure I will get to listen to it every now and again. Anyone out there heard anything similar? Comments etc? Cheers.
