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

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

@roxy1927  Thanks.

@audiotroy   Can you and others expand on why an amp with a "recessed midrange" is a good/recommended pairing with "warm speakers?"  Thank You!

the Dali Epicons are warm speakers an amp with a recessed midrange would be a good thing.

@celander I agree. We need more of what you are recommending and much, much more shared (including additional context) so that those reading can make choices, with higher degrees of confidence and informed processing. Very Well Said. Thank you!

An owner endorsing gear they own is simply bias confirmation.

@celander   I get your point, but what do you recommend?

It's a journey for most of us that [hopefully] moves our understanding and knowledge forward. Sharing where one is, at that point in time, and the choices made along the way [for better or for worse] seems reasonable and fair.
