I am using a Cary Audio SLP 98 tube preamp and 200.2 ES power amp. The sound like the absolute sound review (Dry, Shouty, thin and bright) The same electronic on my quads 2905 sounds musical with no issues. I tried a Prema luna tube amp which improved the overall sound somewhat. NEED HELP

Hi John,

Initial thought is that you have to experiment with room placement, acoustic treatments and available speaker tonal adjustment options. Having had experience with four different ML models over some 25 years or so, they can be difficult to "dial in" but once done, I hope / trust you will be happy. And my last two listening rooms were definitely on the bright / reflective side of the equation.

I read the TAS review and I believe you maybe somewhat exaggerating the negatives. The reviewer did indicate that the speaker is voiced a bit brighter than the Montis, which it replaced, but he had many positive comments about the overall speaker performance.

Good luck.

Dry shouty thin bright is just bad set up. You cannot use the exact same electronics as on your quads, you will have to try different ones to get it singing.

The speaker position may need to be revisited as well. You cannot expect a position optimal for one speaker to work well for another.

John, Can you describe your room and maybe a picture so some advise may be easier to offer.

We have a chap hear who had issues with his Ethos speakers. Something to do with a panel failure on one half of the panel... Not too sure what's going on there.

Anyway, our Aus distributor/importer for ML replaced the Ethos panels with the 11a panels instead! Claiming that they didn't have a direct replacement for parts, which was still under warranty.
The end result, the chap is massively unhappy with the sound! Claims it to be exactly what the earlier post said, bright, shout and peaky... Doesn't like it at all prefers his original Ethos! I certainly don't blame him and only hope that ML or our Aus distributors help him out.

I have contacted my previous dealer network based in Spore, Thailand and HK. All three of them stated an entirely different thing/ solution was to be able to provide a full replacement with the original Ethos panels, no questions asked! So, again a bit perplexing as to what exactly our Aus distributors have done. Whatever it is, it's definitely not sounding any good.

I also advised on run-in time, at least a minimum of 100hrs since these are brand new panels consisting of "Blade" tech which is ML's latest panel version but to fit this kind of thing into an older Ethos I'm just wondering if this is the right approach...

Any thoughts?
RJ

If ML can make me panels from the early 2000s, while Sanders was still there, I bet they can surely make them for the Ethos as well. ML service is phenomenal and renowned.

Exactly! Right?
However our very own Aus distributors are letting this guy down... Now he's having second thoughts of even keeping these hybrids since they've altered the panels with the 11a panels, the bass and integration with the panel is no where close to what he was getting from the original Ethos panels. I'm not sure why these guys did or even recommended such a different kind of panel to install but they did!
I'd still like to see how this plays out though, I'll keep up the updates from down unda. Cheers for now, RJ

He should probably contact ML and discuss directly.

Seems like at this stage our Aus distributors have done all they possibly could. The owner has also received contact from ML HQ I believe and they have assured this was the best solution in order to achieve a full working speaker.

The question is whether this "working speaker" is upto par compared with the Ethos, we would certainly hope so...
On another note, there's been discussion that after these hybrids have actually been upgraded to the new Blade Tech panels, which are quite different to the Ethos panels, perhaps the basics need to be readdressed:
Type of amplification, positioning, sound absorbent materials in the listening room, ancillary gear such as cables and interconnects, the listening room and it's environment in general...

Having gotten used to the original Ethos sound, which he was very used to, now what we have here is something quite different! I also believe that the panels need to be run-in for quite a while before ascertaining if the overall sound is poor to just average.

I've extensively auditioned all the hybrids in the new Masterpiece series and they are all stunning hybrids! Then again they were used with top line tube amps, either CJ, VTL, VAC and the new ARC 160M's. I don't think this particular owner has anything similar or in line with these top end brands but that's a matter of preference and budgets... So I'm hoping that over a period of time, the sound will improve towards a wonderful musical event!

Let's see how it goes. Cheers RJ
