Mundorf (non-oil) Silver / Gold EVO MCap Supreme coupling caps in your tube amp ???

decooney,

I did listen to my exact same tube amp with similar tube compliment with high-end V-Caps and it was a bit too lean for my taste. I’m hoping these new EVO caps sit somewhere in between and still retain a nice smooth sound.

I do believe that the new evo caps would be exactly what you are looking for.I have them in my Yamamoto A09s as coupling caps and the sound difference is much smoother than Vcaps that I had before.Another good choice may be the Jupiter ht copper foil they are not super expensive either.

Here is a link to a very good cap comparison website,

I'm running Mundorf Supreme's silver/oil in my KT88 single ended amp so can't answer your question, but here is another address if you're interested:

You are making me rethink replacing the original Wonder caps in my Melos 222 preamp with Clarity MR cap's though. 

kdude66, boxer12, thanks for your replies and links. Most excellent. :)

The post by Jon L on the audio circle link describes precisely what I was told by the folks who steered me to these more standard Gold/Silver EVO Mutdorfs based on what I am looking for. I was a uncertain about stepping away from oil caps in my amp; but already have oil caps in my pre-amp, and these Mutdorfs are for my tube amp and Jon L on ac notes this - Nice!

quote:
" Silver/Gold has a bit richer presentation from top-to-bottom with a bit creamier textures and a bit closer imaging. As one can imagine from this description, Silver/Gold doesn’t *quite* seem to be as Nth-degree clean as VCaps but renders more proportion of recordings more tasty.

I do not believe detail resolution is any less than VCaps, but a tiny bit more harmonic "bloom" over the notes makes music both sexier and less pellucid at the same time. Some people will absolutely love this quality and call Silver/Gold much "better" than VCaps while others will absolutely declare VCaps to be the better cap for the same reasons.", unquote.

I replaced Solen FC coupling and bypass caps in my Consonance M800SE monoblocks with Clariycap MR's. For a resonable price gave better accuracy, detail and integration top to bottom. My next step will be upgrading the Power Supplies and then Resistors. For anyone with Consonance Amps check out Graham O'Neill mods for Ella Amps.

Thanks. Definitely want to hear back from others who’ve actually heard or tried these newer Mundorf Silver/Gold (non-oil) EVO Supreme caps.

I found the Clarity MR caps to be a little dry. The Jensen Copper Oils were nice and wet, and maybe even a tad slow in my amp. I would have ran them again but my amp has twelve (12) EL34 power tubes, gets pretty hot; i.e. don’t want to deal with oil cap failure a few years down the road. Hopefully these EVO supreme non-oil silver gold caps may fit somewhere between. That would be nice. Can't wait to get them, install them, and break them in. Heard that could take up to at least 100hrs as well. We'll see I guess. 

Kenny / kdude66,
I re-read your reply and viewed the link you sent.  Very good, this helps me to place the Mundorf Silver/Gold EVO caps among others following the sound description provided in the review.  

I'm curious about various differences you noticed switching form the V-Caps to these Mundorfs. Other than smoother, what else did you notice in comparison... ?

decooney,

To answer your question the best that I can,always remember audio is highly subjective and everyone hears things differently.

Using Vcaps in amps and crossovers always gave me a lean and more neutral midrange and I prefer just the opposite. Also in direct comparison in my Yamamoto amp between vcaps and mundorf evo's I found also the evo's to have a better sounding top end meaning more natural and forgiving to worst sounding recordings.
I found the bass to be quite equal with either cap and I can't say there was any overall detail missing anywhere with the Evo.

Dueland makes a small .01 uf bypass cap which I would like to try sometime may make a nice difference in some crossovers in my newest speakers and or amps.

If anybody has tried these I would like to hear about it.

Kenny.

UPDATE:
Doing more research and getting updates about these particular Mundorf Supreme Oil vs S/G non-oil caps, found this. Heat is definitely an issue with my tube amp with 12 output tubes and 4 pre-driver tubes. Runs hotter. This was on the Dynacotubeaudio forum from a few years back. A member in Germany worked directly with Mundorf on this inquiry. I’m sticking with the non-oil Mundorf EVO Silver Gold cap order. Similar to SIO caps. Still running copper oil caps in my tube preamp though.

re: Tube Amps, quote -
"As far as the SIO caps are concerned the max recommended ambient temparature is 70C degrees celsius. That does not mean they immediately die if it gets hotter. They used to be higher (85), but were reduced as they leaked oil in some rare cases, especially tube amps (the viscosity of the oil changes with heat). They never were rated at only 50C degrees.

The Silver / Gold ones are ok up to 85C degrees ambient temperature.", unquote.

Receive the Silver/Gold (non-oil) caps. They are smaller than I expected. Gold wires coming out.  Waiting for my tech to do install in a few weeks. 

Update on Consonance M800SE Monoblocks with ClarityCap MR's.
I have close to 100 hours on the ClarityCap's. I find them dead neutral. They don't add or subtract from the source material. I have updated the power supplies to schottky diodes, kiwame resistors & double the capacitance on the - bias. Also changed resistors to Mills 5 watt for the screen grids & cathode bias. Added diodes to screen grids. These mods made huge difference in detail, soundstage & clarity. Its like a veil has been lifted. Next I am going to try expensive Audio Note Tantalum resistors for the grid of the output tubes. These will replace Russian MLT 5% resistors. I hope they will be worth it.

That is exciting stuff hifijunky! I haven't tries the audio note resistors but really like the kiwame's. Please keep us updated on how it sounds. 

I installed Audio Note Tantalum non-magnetic new version resistors in my left Consonance M800SE Monoblock. I replaced all but two (value wasn't available). For those I used Takman Rey resistors. Total of about 15 resistors(30 total ouch on cost).The right Monoblock still has the original Russian Metal films. Great having monoblocks so you can compare. Checked volume with sound level meter and found it was 1db lower on modified Monoblock than the right one (after every mod I've done the volume is alway lower). Adjusted level on Herron Preamp 1 click to equal.
Modified Amp sounded dull and lifeless at first. After about 15 hours much better. Warm and very detailed. Unmodified Monoblock is brighter, sounds like a transistor radio in comparison. Maybe that is too critical, I like the modified one better. Metal films are known for being bright. Now I'll have to put 6 hours into updating the right Monoblock.
Note there were 2 upgrade kits available for the the DIY Audio Ella amp (same design as the M800SE).
Level 1 was with Kiwame resistors. Level 2 was Audio Note Tantalum magnetic resistors. I am not sure what type of resistors were in the original non upgrade kit. Maybe the Russian MLT's. That is why I went for expensive Audio Note resistors. 
Anyone near Bergen County NJ and what to hear the difference let me know.

Thanks for the update hifijunky. Glad you're happy with it. 

3-years later, update #2. Second try at using these exact same Mundorf Supreme EVO Silver Gold caps in different amps. Great results, again. Yes, they are more expensive, and proving to be worth it in my systems.

Type/Part#:
Mundorf Capacitor 0.22uF 1000Vdc MCap® Supreme EVO SilverGold Black SESGUSD, SKU#: MUNDORF-80510
Note: these are not the oil cap.

Update:
Recently removed well known mainstream poly coupling caps and installed another two pairs of of these in a different pair of Mono Tube amps. Same amazing results as my former tube amps. Just proved it was not luck or a fluke last time around. These caps are truly very nice. Comparing to other Clarity, Jensen, Cardas, Multi-Cap, Orange Drop caps previously used. Kinda like VCap sound but with more texture, nicer tone, added musicality.

RESULTS:
-sounds natural. Piano, Guitar, Voices simply sound more authentic.
-added depth and transparency without any edge or grain at all (nice!)
-guitars strings definitely glisten and there is some added delicacy...
-lower level micro detail comes through yet not overly detailed.
-smooth on top, great midrange, nice tone, beautiful texture is there!
-added layering, intriguing 3rd order harmonics coming through.
-great separation for each instrument, no blurring, separation is neat.
-added decay and air around various notes and instruments.
-added clarity with low volume listening.

Your Results May Vary. Like getting an amp and speaker upgrade in my case. You’ll see these exact caps being used in ultra-high end amps too.

Unexplained:
These (3 years newer version) started forming and sounding good only after 5-8 hours burn in time this go around.  Not sure why, last time it seemed like to took a long time for caps to settle in 30-45 days, and more changes again after 60 days.  Not changing as much this time early on. Will see.  Will report back if the burn-in changes again over next month. 

Issue:
-Waited too long to try them again in my new amps.
-Expensive, but proving to be worth it vs. other upgrades.
-Only way to know is to try them yourself. Not much on internet.

...hope this helps someone. Back to listening.

At 4hrs vs 30hrs was a notable change and then steady improvements continued through 100-150 hours. Up to 200hrs, noticed a nice slow steady change with the Mundorf EVO Supreme SESG Silver Gold coupling caps.

Same musical results in my current mono amps as my prior stereo tube amplifiers. Definitely worth the burn-in and settling roller coaster ride to realize the results.

300HRs+ 

The Mundorf EVO Supreme SESG Silver Gold coupling caps sound absolutely beautiful now. As good in my Quicksilver Mono amps as they were in my former Cary amps. Worth every penny for my system.  

A few other amp owners have messaged and tried them too now reporting similar results. They just keep getting better with time.

The long burn-in and settling time is absolutely worth it. Very musical.

Another M fan here, Now that i upgraded my IC cable (see my latest topic in cables forum), the Mundorf Supremes in the Defy 7 have really come through,,,I was concerned as i modded the Cayin cd player with M caps, the preamp with M caps and then the defy with all kinds of top quuality caps,,yet something was blocking the gains,,i figured it was the preamp,,then I got the new IC cable and , ,all the Mundorf caps now beagan singing w2ith gogeous openness, spacious,  realism, 
No  dount the Mundorf black supreme or the smaller brothers the white caps (for space constrainst and/or budget constraints) both will add textures and openess to your system. 
Highly recommended. 
havea  used Jadis DPL arriving tomorrow, which will be recaped with M caps, plenty of space,,but will have to go white caps for budget constraints, The Supremes would cost a  fortune..and I am not so sure the Supremes are worth the extra 2X's cost vs the white body caps. 
Could you tell which is which in a  blind test?

Yes, the difference is in the fullness of the sound, only after fully burned in - yet I added the smaller White non-evo version to my input devices (DAC, pre) and use the larger black EVO Supreme Silver Gold only on my amplifiers fwiw.  YMMV.
