for the CLSIIz


These are the latest panels to grace my room, after a couple of pairs of Quad 57s, one pair of 63s and the M-L Aerius. They were purchased second hand, sight unseen apart from photos and were not listened to first. Apparently they are the CLS2a's and the dealer performed the "Z" upgrade some time ago. I had heard a pair several years ago and had been blown away by how cool they looked and how ethereal they sounded, even on the Pioneer A-400X I had taken along to audition them on, ha ha. So was confident they would be okay, fingers crossed! My pair have the oak frames which I like the best out of the range of finishes. They are very solid, the construction gives you confidence and the woodwork is first class.

After setting them up in my not-so-large room, a few days were spent positioning them and getting the REL Storm to integrate well enough to not draw too much attention to itself.

Most of the music going through them has been popular or female vocals with a bit of rock and some classical. First impressions were that all the typical electrostatic qualities were present. They are not dynamic in the usual sense, no frequency extremes are obvious and the expected lack of bass was there. Still, on the right piece of music they can convey startling depth but in the main, the REL fills in the bottom end nicely.

The real reason for buying panels though, lies in the midrange. Female vocals in particular just sound right, even with older recordings. For example, Nina Simone singing 'Lilac Wine' could be right there, even though it is a 1965 recording. And much more preferable to Jeff Buckley's version! I was lucky enough to hear this recently in Graham's Hi-Fi in London on high-end Linn gear and thought it was a woman as I didn't know who the artist was. Atmospheric pieces such as Enigma's Cross of Changes envelop you and well-recorded works such as Deanna Kirk's Mariana Trench sound very natural with startling depth in places. When you are in the sweet spot, it is so easy to lose track of time... just one more track... At least one evening has passed with the lights dimmed and a glass of red wine makes a most excellent system upgrade :-)

The Rotel amp I bought to drive the MLs I bought mostly on the strength of reviews and the fact they were discounted at the time. 500W per channel of efficient Class D power for less money than the competition was too good to pass up and my hopes were rewarded with a great sounding amp. It replaced the 2 hard-working Arcam 290s I had bridged and run in mono, 1 each channel. The detail, seperation, bottom end and attack improved markedly. This was more like it. So much so I bought a Rotel RC-1082 to replace the Arcam 290 integrated which had been doing pre-amp duty. The Rotel further improved detail, insight and the bass which I always felt was a weak point of the 290, being muddy, lacking extension and lethargic. So now the MLs were sounding quite tasty. Living in New Zealand, you would think that Perreaux or Plinius gear would be much more affordable. So did I. Yeah, the latest Perreaux integrated is a great sounding, flexible and intelligent piece of equipment, but I think I got a bargain with my Rotel combo.

As I mentioned earlier, I made the pilgrimage to Graham's Hi Fi in London after seeing the "probably one of the best 5 hi fi shops in the world" ad many times. Despite not having an appointment, they made time for a chat and a quick demo. I heard the latest Linn digital server/dac combo and I honestly can't remember what pre amp they used. The speakers were fully active 3 way jobs, so I presume no external amp was used. I heard a few unfamiliar tracks, but I think in the truest testimony to my Martin Logans, all I wanted was to put the very tasty front end in front of my CLSes!


Although this review is a bit meandering, I can in all honestly say that if you like panels and find a pair in good order, grab them. ML don't make affordable full-range panels any more, and there is something special about them.


Product Weakness: Size, demanding of amplification, lacking in bass.
Product Strengths: Speed, transparency, lack of colouration, imaging, naturalness, cool looks.

Glad you like your speakers but it has to be said that any speaker that lacks bass will sound very "fast", just the way it is. Glad to hear that the Rotels delivered the necessary power to your Martin Logan's. Sometimes, nothing else will do except extra power.

I don't think i've ever heard a properly set up pair of MLs... I've been to Harvey's in NYC - when they were still there, they are gone right? - running off Mac gear but always thought the sound seemed to be coming out of a tunnel. Also heard them thru CJ tube gear in a different store and felt the same.

I remember the salesman saying he was an Electrostatic Fanatic!

My biggest problem with MLs is I've always found the transition from the bass to midrange disjointed.The ML fans say there are newer models that don't suffer this problem anymore but I guess I either haven't heard the right model or the dealer hasn't set them up properly. As such, if I were going to go electostatic, I'd probably look for another make.

That's one of the things I like about the CLS, since it's a full range speaker, there is no bass driver to disturb the top to bottom coherence. No crossover anomalies, no cone vs panel sound differences. I had a pair of the Aerius, and after disconnecting the bass unit, the thin sound showed just how much of the frequency range the panel covered... not as much as I thought. Not as bad as the bass unit vs cube you get in a Bose system though, ha ha. And yes, ML aren't the only manufacturer out there but time will tell how reliable the new Quads made in the PRC are, for example. Good, I hope- I plan to get a pair in a few years when they are more affordable :-)

I'm not really sure what you mean by tunnel. My ML's have a definite sweet spot, but also a wide soundstage. When listening in the sweet spot I have the singer standing in front of me with the musicians all in their proper places.

And so far all of our friends (most not audiophiles) have been amazed at the life like quality of the speakers.

I will say that it does take a lot of placement tweaking to get the sweet spot perfect. And then the maid bumps them and.....
