G'day Daniel M,
Ah! Certainly nice to come across another CLX owner. It's definitely a passion!
No doubt the XA30.8 can hold itself extremely well, both in terms of unflinching accuracy and handling that varied impedence swing that the CLX's are notorious for. That impedence curve is lighting quick, changes in an instant, hence this is where many so called highend amplifiers simply run out of steam... they puff out, need to take a breather, get back upto speed but definitely not the XA30.8. I've heard Kostas's system, amongst his fine gear carefully matched with the CLX's, it's a mighty fine combination indeed! I must also mention, the simplicity factor, keeping things simple, and less complicated with shortest possible signal paths, yields purer results.
Speaking of Pass Labs, I've also auditioned their top tier gear, such as the XS300 series on similar Martin Logan stats, more on the hybrid series, the Renaissance 15A and Neoliths. Very impressive but I sincerely believe that kind of raw power is definitely not required on these newer ML stats, which have a much greater efficiency rating. You also don't want to over-energize the room, that's when things get whacky and you simply can't enjoy music, rather it's just one big sound!
It was a few years ago when I first listened to that system, that got me interested and swayed me back towards ML stats. Apart from Maggies, Quads and the CLS IIz, which were the last ones I had, I ventured off ML for a while thinking it was not possible to further improve on their full range stats. However, after listening to this awesome system, from the very first note I gathered straight away, that's it! These are incredible and something truly special, the design and engineering team at ML have put together something radical and very different to the CLSIIz, Monolith, Summit and Statement Evo-II's, harnessing knowledge and technology from each of those previous designs and coming up with this. It's an engineering marvel!
Having Triple stators on the bass panels, which no other stat manufacturer has ever done, it's capable of some serious agility in the bass but the main amplifier has to be up to the task.
There's no other speaker I would rather own.
Although as secondary systems, if I was spoilt rotten for choice, I would still enjoy the Maggie 30.7's and Apogee Diva's, of which I did own many many years ago, driven by CJ monoblocks.
BTW, what does the rest of your gear comprise of?
Source, cables, interconnects, digital analog...
Good stuff Daniel, enjoy those fine tunes!
Cheers, RJ
