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.

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.

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.

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.
