Which would you choose; Pass 250.8, arc 75SE or luxman m900u?

Troy is the energizer bunny of self promotion. He's been doing it for years. Lately, the moderators have been deleting my posts re Troy--but they don't delete his promotional posts which either laud his wares or backhand the competition. It is truly a sad outcome.

No HK_Fan we are the new car salesman of audiogon and we are one of the very few dealers that keeps abreast of the latest gear and keeps bringing in new and exciting products.

@roxy1927   For clarification: You have the Dali E 8 for speakers and the ARC R10 as a pre (?). What is your current amp?

Hegel H30 Nice deep soundstage but as others have said looking for something more exiting. Interesting too that I read in a magazine review certain instruments have less impact on this amp than they would on another amp. I found this to be true!

I would be interested in other suggestions as trudat said to excite my Dalis a bit more which I like a lot and a speaker changer would be too costly and overwhelming at this point.
