I drive my M30.1’s with a Pass INT-25 integrated and supplement the 30.1’s with an SVS Micro 3000 sub. Having heard dozens, more probably hundreds of different systems over the past 30 years or so I’d be hard pressed to think of a combo I like more, for MY musical tastes and space. I lean hard to acoustic music and vocals. I like to hear individual instruments with their timbre and color intact. I like to hear space. I want to remove myself from the "real" world and imagine the performers in my apartment; on many recordings I can do that with these speakers; they’re a great match with the Pass INT-25. there’s a sense of intimacy and delicacy that I just don’t hear with most other speakers. I’m thinking about upgrading to 30.2 XD’s but outside of a pair of those for about $5 or $5.5k I wouldn’t even know what to consider near that price.
