Got my amp back today, very quick, amazing service, it looks sooo nice, will post pics tomorrow and impressions if the ferrite change changed sound quality
Oh oh got you!
You are talking about distortion then...
No distortion with the c421.
In fact, I bought the c421 at first to drive my Denon D5000s (which are actually not that power hungry!) because on my CmoyBB, sound distorted a lot when increasing volume. Same headphone on the c421, clean as a whistle (even with bass boost active! though I did not use this function a whole lot!)
.. I'm curious how does the c421 AP8260 sound with DT 880s, is it strong enough to power a 250 Ohm can..
I have used it with my DT 880 600 Ohm cans it it sounded really good - even on the low setting. IMO it isn't going to give my 600Ohm version everything it needs to make them shine, but it was a very satisfying experience. I am awaiting the return of my beloved amp... I got an email today stating it was shipped today! Less than a week turnaround time
More Kudos to John. I will give it another listen when I get it back and post a fresh impression.
The amp was sent in for the ferrite change and the black end plates- I doubt it will affect the DT 880 sound, but it should on my IEMs. I am sure the black end plates will make it sound even more awesome! (just don't ask me to do any A/B tests or provide any measurable results)
Ferrite change did up the sound, as my Shure SE535 did sound a bit muffled and the bass wasnt tight or quick with severe roll-off before, now they are much better balanced and defined. Great work John
and now for the work of art (so sexy in my opinion):
also replaced 11ohm ferrite with a 2ohm one
arent the black plates a standard now? i just ordered days back. they said black edition
