I've tried the Mundorf caps of various types but they didn't quite make it to the level of the Sonicaps. In some cases (with some models) things went South.
Well, we can agree to disagree.
I found Mundorf caps to be among the best sounding available, with great midrange and treble. Our mutual friend also thinks highly of Mundorf.
BTW, if the caps you showed are made like Jupiter caps, I would think twice about them. I had Jupiter caps in my 8552 power amp, and they were awful. They were literally melting during normal use. Replaced them with Mundorf silver/gold, and the sound improved markedly, and more importantly, they don't melt!
