Clarity Cap CMR Impressions

Hello!
Wondering if anyone has updated their passive crossover with the Clarity Cap CMR.
I'd like to hear how they compare to the MR and comparable competition. I saw some threads on the MR but not these.

Thanks 
Darren

Hello Darren,

I have personally compared CMR to MR in a modified Pass Labs XP-25 phono stage and modified Merlin VSM speakers.  The main technical difference between CMR and MR is the use of a copper litz lattice end cap in place of tin-zinc end spray.  AFAIK, this is an industry first for a metalized polypropylene film capacitor.  Tin-zinc oxidizes during the spray deposition process, producing grain boudaries with variable impedances across the conductive surface that joins the metalized film layers.  To my ears, as compared to MR, CMR has more faithful pitch and timbre, reduced slurring across the frequency range, and a quieter background.  Hope this helps.

Regards,

Dave

Hi Erik,  I'll try to get that info from Factory.  What capacitance values and voltage rating are you using in your application?

Hi Darren, Glad that CMR works for you.  I'm hearing improved tone and texture as well.  As Erik mentions, the splashiness will calm down as they break in.

Eric, I think Audio4pass has it right about CMR. The new CMR and CSA ranges are calmer, in the sense of underlying quiet background, and more natural and unforced timbre and coherence across the entire FR. It takes around 200 hours for break-in.

One of my OEMs who just completed his evaluation of CSA, reported that it is the first metalized polypropylene cap he has experienced with rock stable measured capacitance across the entire break-in cycle. That’s not to say that the sound doesn’t change through break-in, but rather that the copper ends exhibit a stable impedance that is unachievable with standard tin-zinc end sprays.

Thanks for your impressions of the cap.

It’s been a long while since I personally went through a break-in cycle with MR, but I recall a leading OEM evaluator report that 200 hours was necessary to get to the end of it. With a more revealing cap like CMR, nuances during break-in may be more easily detected and thus appear more dramatic, when in fact they may be subtler. Sorry if that seems mysterious, but just give it time and see.
