Can anybody point me to the best place to purchase a couple opamps.
 
I am interested in the following
 
OPA2107
 
JRC4556
 
If anybody here has them for sale that would be great also.

I have never tried it, but I think that is what is used in the Grado RA1, if I am not mistaken, and I very well could be.
 
I was just not sure if  e-bay would be full of fake chips....RAZRr1275

Mouser & Digi-Key.  The JRC4556 might be a bit hard to find (used on some older Creative X-Fi cards I believe).  OPA2134 might serve as a replacement iirc.
 
Is this for your LDI+?
 
The LT1364 is another popular choice.
 
Cheers!

The LD1+ is coming with 3 sets of tubes....Mullard EF91 matched pair......4080A Sylvania gold matched pair....Mullard EF92 matched pair
 
It also will have 2 opamps......I will get 2 of these 3 listed....I just don't remember which ones for sure.
LME49720
LT1364
BB OPA2134

Great sets whirlwind. IIRC, you are also on the Grado thread. The Grados love this little amp.

Congratz!

Only tested one of the ones you mentioned, but I tested several opamps other than the usual ones here:

I just ordered two free samples of the 2107 from TI, and I picked up a matched pair of Voshkod 6J1P-EV tubes, and I'm still waiting on delivery of the Little Dot I+... I'm getting started even before it arrives.
