I just wanted to chime in here now that I just got my Darwin Ascension ICs.
WOW!
Okay, enough hyperbole-just kidding, I meant it.
Having half the capacitance of the standard Silver ICs (which are no slouches) these Ascensions deliver in spades. Coherence, timing, that misnomer 'speed' which can now be used without guilt, detail, ambience, tighter firmer bass, oddles of nuance, you name it, it does it.
What these ICs give is a more complete end result, be the note, the separation, the phrasing, the accompaniment, the very back of the venue. I can now tell just how quickly the cymbal closes on Brubeck's "Take Five" and when the bassist lets the note go and splinter and then tightens up his grip, and all the background playing on "Build Me Up From Bones" by Sarah Jarosz which beforehand was nothing more than musical smoke ( there's so much going on there).
None of this great detail retrieval is at the expense of anything else nor is it highlighted or exaggerated. It's just there. Bravo!
If anyone is on the fence about getting these, then do what I did: sell off some old gear or eat less for awhile as I don't know how long Tony will offer this discount. On another note, now that I have all my ICs from Darwin, the regular silver ICs went on my Marantz tuner which sounded like one you'd find playing in someone's garage to a great way to listen to FM. Who says that nowadays?
All the best,
