Those blue lights seem cool for a while then like they're looking at you. 4 ohms should be better; less resistance. The tube sound is so realistic and evidently so are the Montis, even if you have to dust em.

Nice review ... but i'm puzzled to hear of no comparison to the Spires, the speaker it replaced. They both use the same exact panel and woofer, with the Montis performing the filtering in its DSP versus the analog filtering used in the Spires that was from the venerable CLX series. $1500 more is the price one has to pay to have the DSP compared to the Montis. The two speakers are practically sonically identical (+99%) to most listeners but the Spires can be had for $5000 or so now since they've been discontinued.

Martin Logan speakers are grade A junk. They lost their company to another company out of Canada. They used cheap supplies and crap labor to slap together their speakers. If your speaker breaks, it'll take literally years to get it into their repair shop, fixed, and sent back. They have trucks upon trucks of broken speakers waiting to be fixed.
