I bought Dueland Alexander caps one time, they finally sounded great, but first 500 hours, pure fatigue.

Jupiter 10uf and 15uf copper/paper/wax caps came in today.  Just got them soldered in.  Listening to my first few tracks right now.  DAYUM!  These are a huge, huge, huge step up over the ClarityCap MRs (bypassed with .22 Jupiters) that I was using before. 

It's like switching from speaker wire made out of aluminum to speaker wire made out of very good copper.  Which, in a way, is exactly what I did.  At this point, as far as I can tell, there's not any aluminum foil in any cap anywhere in the signal path.  Except maybe in my Auralic Vega, but I'm fine with that, for now - hahaha!

Anyway, a bit more info on the sound change - DETAILS!  They just jump out at you.  I feel like I've never heard this level of detail before, on any system.  It's at the same level as what I normally hear from top-level headphones.  And everything sounds much BIGGER!  More life size.  Hell, maybe even larger than life (which I love).  Downsides?  They clearly need some burn in, as they are a bit rough/gritty sounding with zero burn in.  But even the grittiness isn't irritating, rather it just presents everything with a "Tom Waits" sort of vibe. 

I'll report back as things develop. 

After about 5 hours these turned nasty - shallow, etched, flat and spitty sounding.  I’m at about 30 hours now and still pretty rough.  Sigh.  How long is full burn in?

Sadly those caps should take a long time to burn in. I am sure they recommend 400 to 500 hours.

Kinda makes me want to pull out my solid state amp to use during the burn in.  Save some of the tubes life.

That's what I do when burning something in. Hook up a SS amp and leave them playing almost 24/7. I turn them down real low at night then louder during the day when everybody is gone. That will get you there in about 3 weeks.

I found they didn't start coming onto their own until at least 300 hrs and very close 400 hrs they were pretty close to 95%.
