Raven Audio caps. I know nothing about them. But here it is:

Let me know if you want to try a pair of our RavenCaps. I have about 1,000 of the .47 and .68uF value. If you want to try them I will send you a pair. Then you can let everyone know what you think. I think you might be surprised.

Sincerely,

Thanks for the offer. You might want to also contact Tony Gee at Humblehomemadehifi as he has reviewed a plethora of caps.

Anyone tried different caps in their Zu speakers? I have Clarity MR now. My Zu use ASD1001 so maybe this is a moot point, or maybe it matters more than ever?

I'm trying to order some Jupiter Copper in Foil caps for my Zu Union Cubes. Parts Connexion has a good special right now, but I think the leads will be too short, and I don't have the resources where I live to modify them properly.

Sean at Zu suggested 1uF 100v, but then I saw some comments on DAR blog (at bottom) about using smaller values:

I don't think the Flats will be an upgrade over MR, just a different presentation. I think you have to get into VhAudio/teflon/Deuland territory to improve on the MR. Also Tubestore still has some Ampohm Copper/Tin Foil, etc caps left. I think those would land you somewhere in between in terms of presentation.

The current plan is two swap out the Clarity MR for some 600v .47uF copper in foil Jupiter caps.

Zu advised I can find some possible added benefit with another .1uF bypass cap in parallel but I'm probably not going to do that right now.

Hi,

Good luck with swapping your capacitors. Hope you hear an improvement.

Cheers Rod

Doc how is the captain been treating you?

I'm curious as to what the value and purpose of this cap is now in the ZU crossover that you plan to swap out? Also how many capacitors are employed in the ZU crossover design? Do you have a schematic for the crossover?

Let us know how it works out doctorcilantro.

I have Clarity MR in my crossover and at the time was unaware of the Jupiter copper foil caps when I ordered my speakers. I doubt I will change what I have now but I'm always curious as to what the difference would have been with the Jupiters. Good luck!

Given that they're in your speakers the Clarity MR will probably be more comparable than if it were a decision at line level were the difference might be more night/day.

PHE426 , underrated in other reviews. I can concur it's a fantastic capacitor. It lacks some detail but vinyl tube lovers should consider it. It's accurate in timing, and gives nice tonal, bold, sound so it might compliment a thin system well.

It's a passive crossover using a single cap. I'm going to secure the Jupiter with adhesive and maybe a zip tie to the driver.

Good to hear from you, I think the ship has sailed for the Captain.

Doc I can't tell where that cap connects at both ends is it running right from the positive and negative of the driver? Or does it go down on one side to the terminal strip? Also what was the original stock value of the cap?

It is 1uF and I don't have them open yet so I am not sure myself!

NOS Valves · « **Reply #792 on:** 8 Jun 2015, 02:50 pm »

well I can tell you that I'm 99% sure that value is crucial and if your change the value you will screw the frequency crossover point or response of the driver by changing it. Which in turn will skew your comparison. I'd be asking ZU about it.

doctorcilantro · « **Reply #793 on:** 8 Jun 2015, 07:04 pm »

Sorry I meant the original value is 1uF and they advised I could go down to .47, and a few others suggested going lower too. So I have the .47 coming soon.

NOS Valves · « **Reply #794 on:** 8 Jun 2015, 08:59 pm »

well I'd be asking them what the sonic effect is by cutting the value of that cap in half.....or if it was me I'd be wondering is the sound difference the quality of the cap or the 50% reduction in value... cap values are always chosen for a electronic/frequency response reason.....

It's really hard to tell with Zu. These guys don't use much in the way of filter components anyway, letting their drivers play further into their range than most manufacturers. Not my cup of tea. A friend auditioned a pair along with a pair of Focals. Not really close. The Focal's stayed. As a rule, changing the value of a cap clearly changes the frequency of the 6 dB roll off.

Craig - you were right. I double checked and some SERIOUS miscommunication had gone on.

So, if anyone has a need for (2) Jupiter 600v .47uF, PM me. sigh.

If I was going to run something in parallel to the 1uF, I'd start with a 100v .1uF, but at this point just going to try 1uF replacing the ClarityMR.

NOS Valves · « **Reply #797 on:** 10 Jun 2015, 01:19 pm »

you could order another pair of .47uF and run them in parallel with another .047uF of your choosing... that would equal darn close to 1uf, but ideally a single 1uF would be better for a true comparison to the clarity cap.

Hi Jon,

As you may be aware, the RAAL 70-20XR tweeter only needs a cap in series (4.7, 6.8 or 10uF depending on sensitivity) to form an LR4 HP filter at 1.8kHz.

Give the relevant pass band, which cap would you recommend for ultimate treble reproduction?

Thanks.

I've just started trying the MKP1837 from Vishay. It's a wonderful bypass capacitor. I'm sure for around 100x the price they can easily be beaten, but they're awfully good.
