Baranowski, I kind of had the similar experience,
I was using a Marantz avr with B&W 805 center anyway I changed the whole thing
first I did'nt want to doubt the power of a very good AVR like the Arcam avr400 for now if the avr600 upgrades to HDMI 1.4 I might be tempted but the truth is the Arcam avr400 is very powerful at 90X7 wpc not two channels like most avrs companies, as well the Arcam's power is just awsome it will drive and hold most speakers to the wall, right now I have Merlins VSM mme they're sensitive at 89db so works well for me.
good luck finding the missing link.
