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!)

Yea and it's not the cMoy this I have confirmed... it's the files and ALL OF THEM, that WHOLE album sound like garbage... I must got a bad rip of it sadly...

 

That being said I'm sure I'll still buy the c421 [you have the AP8620 one yes, my cMoy has the 2227 chip and I don't want another amp with that chip, one is plenty <3]

 

But yea the cMoy is fine it's the files... such a shame! Still though as I said b4... I'm sure I'll buy this amp just for the heck of it <3

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 biggrin.gif

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 dt880smile.png)

Just ordered my c421 op2227 a few days ago, has anyone ordered it from singapore? im want to know an estimate for delivery. Found out the free engraving after I ordered, sent an email few hours later and they managed to personalize my name on it. I'd say thats freaking great service! By the way, anyone has an experience with the c421 op2227 with the westone um3x and ipod classic?

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):

Great pics! Well, I must admit I'm enjoying the black endplates more, so I think I'll go for those too... beerchug.gif

nothing, John is a great guy, he will replace the ferrite for free, you pay for the black end plates and you can get free custom engraving with every order.

 

mine went from portugal to the US and back in less than 2 weeks, amazing service and super quick. also the work is top notch, i highly reccomend JDS Labs.

Now they're a standard with the "Black Edition" c421, but who bought it before this new edition, it came with thinner silver plates...
