As many may know, Clarity MR has been selling at a discount as the line gets discontinued. Over at Audiogon there have been a few postings which sound genuine I though I would share.
Since it's a public forum, I did not ask for permission, but I did cut and paste the "juicy bits."

==================
First:
=============
The new ClarityCap CMR CopperConnect range will benefit even less from bypassing than MR. CMR has the MR series-wound construction and resonance treatments, with the addition of a copper litz lattice embedded in the end cap. This reduces impedance and phase anomalies across the conductive ends that (in traditional metalized film caps) result from oxidized grain boundaries in the tin-zinc end spray. This is a significant improvement.
===============
Second:
================
Madisound and Parts Connexion will have CMR & CSA in stock soon. I can provide free samples to substantiated manufacturers. I run an occasional group buy for hobbyists and smaller OEMs who need custom values or can’t justify factory MOQs.
Since the surface area of the end spray increases with diameter, the benefit of coppering the ends is greatest with the higher value caps. This led us to shift catalogued aspect ratios toward larger diameters and shorter lengths. In turn the narrower metalized film stock employed further reduces ESR. The downside is that fatter caps may not fit in some applications.

IMHO, the shift to narrower, larger dia. caps occurred about the same time cap manufacturers discovered they could wind better and avoid the resonance and ringing issues that plagued caps in the past. Just take a quick look at a variety of better quality brands. You'll notice most have switched to the narrower, larger sizes.
from my experience, it was only the larger clarity caps which benefitted from bypassing, so id suggest doing listening comlarisons with thise. Sadly, small clarity MR caps were still at least $30 so multicapping large values became very expensive quickly.
Ill be trying a couple as soon as I can.

Bypassing a poly cap with another smaller poly cap is a great way of causing resonances apparently.
Theoretically. Practically these resonances are far above audio band and/or are of low q-factor, so they will never be excited significantly by audio signals. Just another audio legend.
Sometimes caps must be paralleled to attain a non-standard uF target value when recapping an old speaker. This could include a large cap paralleled with a 1.0 uF cap or less for example. We'll have to live with that.
It's been my experience to limit bypassing with only film tin foil caps.
Of course we're beginning to veer OT with the BP discussion.

In that situation, I do my best to split the caps evenly, 50/50, 33/33/33, etc...
Cap bypassing or mutli-capping is standard engineering practice, so saying that a cap is lousy because it behaves better when paralleled is nonsense. Of course, some cap bypassing is also nonsense.
Having said that, the total $$$ value must be evaluated. Bypassing a $100 cap with a $120 bypass cap does make you wonder about the quality of the original cap. 🙂
To each their own, but I like Clarity as do (cough cough ) other famous speaker makers. So, 😛

are you sure that MR and ESA series will be discontinued ?
i think no, because on site for example there is 47uF ESA 630V, but 47uF CSA 630v not listed, only 250v version
who know this ?
guys, about new copper techonology in clarity cap, is really better then old tech ?
thank you
In this application, if it needs bypassing, it's lousy. Speakers don't operate at VHF.
Of course in this context, "needs bypassing" doesn't actually mean "needs bypassing."
Hi Everyone,
I wanted to update this thread with some product info as well as a mini review.
Clarity has introduced CSA and CMR which update the ESA and MR lines. Based on the sales prices, and discounts I thought the old lines were being discontinued. I have confirmation from two sources, including Clarity, that this is no the case. The ESA and MR lines will remain in production.
I've recently updated my 2-way speakers with Clarity CMR in the high pass filter. The speaker itself is a Mundorf AMT and Scanspeak 6.5" Revelator. The high pass is a 3rd order with L-pad.
I am comparing MR + an audyn 0.1uF on the largest cap to CMR. The Audyn 0.1uF added liquidity to the midrange.
The CMR caps sound overall like different caps. They are brighter/cooler caps. Sounds from the surface of drums to top hats seem more prominent. They go towards the Mundorf Supreme sound without the juiciness of the silver/oil.
Over the next week or so I'll try bypassing the larger cap as well to see if it is worthwhile, I will say the midrange sounds pretty good as is, while the MR caps really needed bypassing at > 5uF or so.
Best,
E

Are there any reliable tests that prove audible differences between caps? How about no cap vs cap? Is this all just placebo?
Not trolling, just curious. I dont know enough about the science to form an opinion

Hi Frangus, yes, it is all placebo. 😉
I'd suggest the best way to learn is to try a cheap experiment. A lot of hobbyists have tried replacing electrolytic caps with Mundorf MKP's and had good results. They run about $7 each. If those caps sound exactly the same as $1 electrolytics, you will know.

Audible and measurable. No cap is best, but that's not really an option in a 2+ -way loudspeaker, usually.
Thank you very much for your opinion.
Over the last years have steadily been migrating to MR as a reasonably priced coupling cap option. Do you reckon the new sonic signature may in some systems be undesirable? Your comparison to Mundorf prompted this question.
Looks like there is little to no info on the new CSA. Judging by the improved clarity of the CMR, I hope we can expect the same from the CSA.
Judging by the review of the older ESA, a little clarity is exactly what the cap needed. I'm patiently waiting humblehomemadehifi's rating, but I expect the new CSA will be the new value leader. The ESA's already were rated 8.5.. so hopefully the new CSA's go up two points. A warmish cap with great clarity, spatials, and details at cheap prices sounds like a great win to me!
The CMR's look to be a total package depending on a persons tastes. Those prices are a bit too steep for my income though. Lol!
