That looks good. I'm sure it sounds better. Over the summer I put those exact caps along with the 2.2uF version in my SEX amp with C4S. I study while I listen to my headphones, and I find that I'm not very productive when my jaw drops and I rewind the music to hear passages over again. I hope those caps treat you like they have me.
I fixed my post to say I put in the 2.2uF caps. I had .47's on my brain as I have those for a pair of Dynakit Mk IVs which I'll be upgrading next.
Yeah, I have 1uF ESA caps as the output caps of my Sex amp as well with a giant V-Cap in the .1 cap position. It's probably the best sounding of all my gear including my mucho-expensive bryston integrated.
