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.

I'm not sure where you've gotten your information, but it reads like bad fiction. I've had the pleasure of working at an independent Martin Logan dealer in Canada for the past 13 years. In that time, I can honestly say that I've only ever seen a handful of Martin Logans ever requiring service--which in itself is impressive, but the statement that you can't get the items fixed and that they have "trucks upon trucks of broken speakers" is pure, unadulterated B.S.
Maybe American retailers do it differently, but when one of my clients informs me of a problem with their speaker, I have them bring it to me, I assess the issue, order the replacement part needed from the manufacturer, and install it as soon as it arrives, so I can get it back into the hands of a happy customer. typically this whole process is completed within 2-3 weeks and my experiences with Martin Logan have been exceptional. By virtue of their technology, electrostatic hybrids are a lot more complicated to work on than conventional dynamic speakers, but I've found the technicians at ML to be extremely helpful in providing me with whatever diagrams and instructions I have needed on the rare occasions that service is required.
The only time before this I've ever heard anyone speak negatively about Martin Logans it was because they were an embittered salesperson that worked for a competing store that was unable to get their hands on the product. . . just saying'. . .
