Links are fixed now guys. Sorry for the wait :) Enjoy!

 

Ugh... the opamp and tube sections are screwed up and hard to read. I'll get to them... eventually...

I have a question about the Opamp(s) listed on the first page.  What are the actual part numbers for:

 

OPA627

Sun HDAM

AD823

 

For example, there are several OPA627 listed on Digi-Key and I'm not sure which part number to buy.

 

Also, has anybody tried the duel OPA627?  What are the advantages over the single chip version?

mtwill54, the single OPA627 won't work in the D1. Think of it in terms of channels. The D1 is a stereo device so you need a dual opamp. Look up the BrownDog adapter. It allows 2 OPA627's to be used in a single socket. There may be clearance issues though.

I wouldn't use the AD823 because of the high DC Offset. It may ruin your headphones over time.

 

For the HDAM, see here:

You'll have to measure and see if things will fit since the HDAM is pretty big. I know for the cost that I would rather have the HDAM instead of the OPA627.

Spanky,

Is the Sun HDAM still the opamp to get, because it doesn't clip?  I'm also interested in the Moon and I'm wondering at what point the Moon would start to clip.

I've not personally experienced clipping on the D1 nor have I owned a HDAM. When I did research them, I would have gone for the Earth HDAM since it's (I think) the most neutral.

Yea the D1 I don't think is properly grounded always I remember the story of feeling of a few volts of electricity passing through my body when I touched the RCA inputs/out  I don't remember how but the problem fixed itself but was still a bit funny.

I thought I was the only one experiencing this! Now I don't feel as insane as before LOL. It's especially prevalent from the tube output - I can send a nasty pop/noise to my speakers if I simply touch the rca cable to the output.

Maybe you can hold on to the RCA output and you will start singing whatever that is being fed to you o2smile.gif

Where's the best place to buy this?  And is it ok for me not to change anything on it?  I don't know anything about amps or headphones but I decided to get the Senhenseiser 650 and people have suggested I get this amp/dac.

You can get it from the chosen place: www.mav-audio.com

No need to roll any opamps. Just connect the cables and you can use it.

Ask Ryan (seller) to ensure that the unit has got no noise before shipping it to you. Don't think that is a very prevalent problem, might be affecting only a small batch.
