Line conditioners and ML ReQuests

I talked with Gayle @ Martin Logan last year about this same issue. He stated that upgraded power cords and/or line conditioning would not have an effect on the speakers sound. Knowing how much better my components sounded with these upgrades, I found it hard to believe that his statement was true. I tried plugging the originally supplied cords into my VansEvers conditioner. I noticed virtually no difference. I then tried Synergistic Research Master Couplers plugged directly into the wall. Also virtually no difference. Lastly, I tried the Master Couplers into the line conditioner. Still heard little to no change. Gayle was right! The only times that I've heard improvements in my Quests Zs is when I bi-wired them and after they are vacuumed.

You might want to contact Martin Logan on this as well as Mike VanEvers. I find them (ML) to be very helpful. If you are trying to get rid of the slight edge you described with these tweaks, I don't think you'll be successful. What you are hearing is your solid state amp driving the panels. If these are independent tweaks, another story. I've actually used the TeknaSonic C-10's and C12's on a poorly dampened ribbon hybrid speaker enclosure and they made a slight difference (2 on each enclosure). I'm not sure how they would work on the Request enclosure. Sorry, but I don't think this will work very well with your speaker. ML hybrids have a challenge in intergating the woofer and the panel, but I don't think there are any inherent problems with the enclosure. Audition a good tube amp first, and go from there. I'd be very, very careful about adding PC's that filter to your speakers. Don't know about more RFI/EMI, never had any problems. Good luck.

I was going to present this question to Mike Vanservers (LC/PC guru)if conditioning power going into the transformers has any appreciatable value on the internal sound floor of the ML's. I might be spending money where it is not needed. Another brothern here mentioned using a Monster HTS1000 at each speaker with TeknaSonic c-12's with great success. The jury is still out though. Question? Aren't ML's known for generating a lot of RFI/EMI/? back into the power source. Thanks and take care.

Curly, if you do this please let me know how it turns out. I thought about getting better power cords for the transformers on my CLS's, but the guys at ML didn't think it would make a difference so I never followed up with this idea. Gut feeling tells me to steer clear of any real filtering, though.
