JDSLabs C421 Preorder is live... - Page 30

I am not much worried about the dial as much as I am about the bass boost switch. I plan on switching it on/off occasionally and so I have to be quite careful. I have just applied a temporary fix with some tape and it seems to be doing its job.

Well, if you are really that worry, you can file down the switches themselves so it is much less likely you will flip them accidentally.

heres mine:

Looks exactly like mine, how weird!

haha, i just thought i'd add a few more pics, the same as others.

but you get the size comparison vs iPod Classic :)

I see you are using Shure SE425s with the amp.  How has the amp affected that particular IEM?  I have the same IEM so I would love to hear what you think of the pairing.

Cheers!

it seems to highlight their strenghts, the bass becomes more articulate with better control, and the soundstage widens quite a bit.

not a huge difference but it is a difference and for the better. i really like the pairing, as they continue with the excellent detail, but with better bass/highs balance, to compliment those lovely upfront mids.

i have been listening to this setup since 11 this morning (now 16:30) and have been loving every bit of it.

Good call.  I did this once, flipped from low to hi gain trying to change the bass boost setting without paying enough attention.  Let's just say I won't make that mistake again....  :) 

Ah see, I'm not the only one . It has happened to me several times with different equipment and I can tell you it's not something you want to experience ever again.

Hey guys,

Which Portable DAC would work well with this AMP and an Ipod Classic? Would the AD8620 or the OPA2227 be better with the HD-25?

Sadly, you need a specialized DAC to work with an iDevice (iPods, iPhones).  The only stand-alone one portable iDevice DAC I know of is the Cypher Labs Algorythm Solo (or CLAS).  Unfortuantely, it is expensive ($580 USD).  Other options include a few integrated iDevice DAC + AMP devices such as the Fostex HP-P1 or the V-Moda VAMP, but both are even more expensive than the CLAS, and include an amp which is redundant in your set up.  I think a lot of us just make do with the internal DAC in the Ipod and use an LOD (line out dock) such as the Fiio L9 or others (they range from a few bucks to several hundred) and an amp such as the C421.  Personally I have the same headphones as you, and an iPod Touch (4G), and I bought the OPA2227 version of the C421.  I couldn't be happier with the pairing!  The 8620 might tend to the bright side with the HD25's, but then I've never had the opportunity to try it.

Maybe I'm going to have to sell this amp... I need to adjust the gain of my mp3 files and bring it down to 72db in order to get proper volume control with my ES5. And after having compared for a little while, the improvement is quite marginal from the ipod H/O that I'm starting to think that it's not worth it. Somebody at hydrogenaudio is calling me a "stupid hipster" for using portable amps for IEM's because this decreases fidelity and increases gain. Well I've seen many people using portable amps with IEM's on head-fi, so are we all stupid hipsters or what ?
