Define decent footprint.  My footprints look quite fine on the ones I laid out.

I have a hard time to make it fit the way you have done. Anyway, I'm ordering pcb's soon so if anyone want a panel or two, hurry up to sign and pay.

I'm checking interest

 
The only thing I can say is that I tried those adapters: http://cgi.ebay.com/10pcs-Dual-SOIC-to-DIP-8-Convert-PCB-Adapter-SMD-OPA627-/230408616394
 
this ad is clearly being b*tchy towards the Browndogs...but I've soldered one of each w/ two LT1363CS8, and the FR is very balanced on the Browndog...but the sound is very bright and most likely oscillating on that ebay adapter. I realize LT1363 is very fast, so it might be an extreme case scenario...I will try again w/ OPA211 and OPA827.
 
I tried those opamps in my Firestone Spitfire DAC that runs on a linear regulated ±12V PSU.
 
I'd like to try your adapters BTW

Sure you can try if you'll sign up for the group buy. Notice also that the Ebay adapters are ten times more expensive.

 

[leeperry]

well, your prices are not clear...how about some prices in USD/EUR? and how is your adapter better than the Browndog?

Divide by 10 to EUR. Pretty easy. A few seconds with Google since Google has a built-in exchange calculator.
 
Better in the sense of having decoupling caps and wider traces.

Decoupling caps?
Your not using bypass caps?

 

[peranders]

It's the same thing. If you wonder how they look like you could check the pictures and the documention.

I really want to try these out...have a bunch of different opamps in soic packages that I want to try in my DAC I/V and filter sections.but am not sure about the quality. 

 

[peranders]

15 cent a piece, not much if you sign up for the group buy. The quality is excellent and they will look like this.

Not the last time I checked.

What is the difference then?

Pcb's are ordered and will come next week.

Decoupling is used on the signals, bypass is for the power rails.

Can you give any reference to this claim since I never have heard it.
