I have put my cls 1 up for sale and have begun saving. That's serious. I have not heard the CLX yet.
When I bought my first pair of CLS I wa seriously into maggies. I heard the CLS while auditioning a preamp. My point is ultimately my ears will make the decision.
I still would live to see a shoot out between the MG 20 and the clx.
Also the escalante and vmps ribbons are in the running.
I think auditioning in one's home is key. However, there are several challenges:
- picking out the speakers for comparison - spending $20K, it would be silly not to do the due the diligence, even if one obviously biased. In addition to ML and Magnepan, how about Kharma, Eben, Magico, Wilson, or others?
- availability with the chosen models - many of the brands are "exotic" and may not be available in your area
- the dealer parting with the speakers - the suckers are heavy and can get nicked easily. May not be a good proposition for the dealer.
- the right setup in one's home- the room is always a challenge
- the matching electronics - ML works better with certain amps and preamps than others; so does Magnepan, and the others - are they available so you are hearing the best the speaker can do?
- can one afford those matching electronics, or is one's system not reaching its potentially with weak components? So many people make this mistake.
As for CLX vs MG 20.1, I have never heard them side by side, but the MG has a much warmer sonic signature, and is slower. It would be my second choice. CLX is the typical Logan sound, but with much bigger soundstage, more open, faster, more coherent. It's everything people love about ML, but much improved upon.
