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


Anyone have good luck with these caps in your tube amp?

>> Mundorf (non-oil) MCap Supreme EVO Silver/Gold coupling capacitors << .22uf / 1000VDC

Previously tried Clarity MR caps and Jensen Copper Oil caps in my prior (same brand) tube amp with decent success. The Jensen oils were nice and a bit more syrupy sounding than my former Clarity caps, were too harsh for me. Looking for something in between. Normally I almost always prefer oil caps; maybe not this time. We will see. For my newer tube amp, a few folks who modify/upgrade Cary tube amps recommended installing these Mundorf (non-oil) Silver Gold Supreme EVO caps - reportedly for a bit more "open and extended air, ,with more bass, and still retaining a nice lush sound" as compared to my former Jensen oil caps. 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.  

Thanks in advance for any replies.

decooney,

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.
