The best coupling caps in power amp ?? Mundorf, Infinicap ??

I just did Claritycap MR's in my Consonance EL34 Mono Blocks. I don't think I could fit CMR's. Replaced $2.00 Solens. I couldn't see puting a grand worth of caps in 2 grand amplifiers. Still breaking in. So far better top to bottom balance & accuracy. Much better bass.

hi all. I'm not an  expert in electronic.
I'm planning to upgrade my pathos tt amplifier. coupling caps. resistors
I emailed to Pathos and they dont recommend to put in mundorf silver gold oil caps. pathos said that they had problems with mundorf caps becouse of the heat in tt amplifier. any thoughts ?
would be great for advice !

Hello everyone!
I know what the subject is not new!  
I have an Airtight ATM300, I really like the amp, but I'd love it if the low and mid bass were drier! I am thinking of replacing the coupling capacitors (Sprague) by Mundorf or Vcap!
Please, any suggestions?
