Electrostatic speakers and low volume resolution

"BTW, and somewhat off subject, some time ago I started a thread regarding phase testing using pink noise and how I noticed some migration of the sound as I progressed through increasing frequencies. I performed the same test after I did the automatic room equalization and, although this resulted in auto adjustment in only the lower bass frequencies, this migration of sound in the upper frequencies seems to have been reduced.

That's a good observation. I don't know if FIM distortion would be the proper technical term, but that's kind of what's happening. By having the lower frequencies not proportioned correctly, they were having an effect on other frequencies.

Something similar, that you can try with your EQ, is to do the same thing with sounds that are bothering you, and the EQ is not helping. Sometimes, if you try to lower specific frequencies with an EQ in an attempt to fix an annoyance, you'll find that sometimes the problem gets worse. What happens is that along with lowering the problem sounds, other elements that are in the same frequency range, that are not giving problems, get lowered as well. This may actually have an enhancing, or spotlight effect on the problem, because you're cleaning up everything around it. On occasion, if you're lucky, you can actually raise the EQ frequencies that you are working with, and the other sounds in the same range, over power the problem. I know that sounds counter intuitive, but it does sometimes work.

ZD, thanks for the clarification and I DO remember your advice/suggestions regarding the use of an equalizer as a potential solution so your response was a little confusing. On the same subject, I don't remember if I thanked you for that but I'm doing it now; addition of the equalizer has been one of the best single things I've done. I don't always have it on but when it's needed, I don't see another way that I could've had the same success addressing my personal issues.

I'll do as you suggest here and try some of these adjustments, as counter intuitive as they may seem

Whart, I've used Martin Logan electrostats for about 35 years now (SL3, Prodigy, CLS2, Odyssey, Ethos and a center channel which I don't remember the model of) with all kinds of decent ancillary gear so am no stranger to their unique demands. In so many ways I like, or have at least become habituated to, their sound so I'm not likely to give them up. I agree with several of your comments but, even though I recognize the possibility, I'm not convinced that their efficiency is the problem.

Hi Broadstone, There's a thread on the Marin Logan Owners website that has the title," i tried 34 amps in 12 months with the Montis, My review is here."

In this thread the OP makes the following statement:

"This brings me to the mark levinsons h series (532h and 533h to be specific). They are THE ONLY amplifier that i can listen to at low volumes and HEAR everything and each detail. It doesn't lose a thing even at low volume. I have never experienced this before."

You might want to check out the thread. The guy is still trying different amps so you might want to talk to him.

Thank you for pointing this out. Right now I'm waiting for final membership verification from MLO and will read his post later on when I'm back home. Based on what I've read, the Mark Levinson amps are certainly very capable and I assume that his observations are valid and would transfer to my speakers. However, the models mentioned are a little out of my financial comfort zone right now especially since I just bought the new speakers and have no way of auditioning these amps in my home first.

A super tweeter is one that operates at about 10KHz and above. A regular tweeter might only roll in at about 2KHz or so.
