I finish modding my D10 as well some time back, I guess we all stop after completing OP_AMP rolling. I am using it more as a experimental test bed now. I just completed a hyper modded D4 for a friend. added a 5V to 12V DC converter using AD797 and BUF634 as well, waiting for AD8610BRZ before finalizing. It is much better than my D10, smaller in size, and so far can drive any headphone I throw at it.

For the resistor mod I am thinking along the line of reducing resistor noise since we are using OPA211 which have a noise floor of 1.1nV/Hz, The 2K resistors noise is already a few times that. I am thinking of reducing it to maybe 600ohm to see if it made a difference.

I am still glad I have my D10 in this state though in case I must go down the shops in a hurry with only my shorts and/or need longer battery for a long trip. in this case I do not miss too much, but I do miss something huge and authoritative power

Darn, are there any canadian sellers for bg's? or are there any other recommendations for bypass caps?

 

[qusp]

you might try reading the last couple of pages; I have already covered that i'm not 100% sure BG are the best for bypass caps anyway

PCX has 440's and 220's but I'm looking for .1 uf and 22 uf BG's.

I've installed the OPA2111 in my D10 with AD8656 buffers too.
Sounds very good, except for a slight background hissing that's really annoying.
Anyone has the same issue? All my other opamps produce a very clean sound... Are there faulty OPA2111KPs?

 

[qusp]

I recommend catching up on more recent recommendations for sensitive IEMs, we know much more about this dacx/amp now. I cant remember if I even still have the OPA2111 will have to have a look

Hi, I just received my D10 and quickly (at work) tried it with Klipsch Custom 3 IEMs via USB and whoaaa !
I'm far from being an audiophile, but my tracks are far more enjoyable with this setup than with my iTouch+FiiO E5 or E1
I like this DAC so much that I just ordered an iRiver iHP140 from Ebay

Is replacing its 40GB HDD with a compact flash or SDHC very difficult ?
I mean if I open it, will I be able to reassemble it easily ?

It's not difficult at all, however you should start reading up on rockbox as you'll need that to install a solid state card.

No problem, in fact very few of my electronic gadgets runs on their original firmware

There is good information over on Mysticriver:

iriver H1xx Series (H110, H115. H120, H140) - MisticRiver :: For iriver Enthusiasts

I have 80gb in my H120 and 120gb in my H140's.

hello
I asked what is the best combination for the opamp Ultrasone Edition 9?
I thought about ADA4841 2 xAD8656. ADA4841 can better turn to another only on what is best?
sorry for my english

cheers
