I have 5 couples of original OPA637AU for sale. They are in ESD safe package.

 

And also 2 OPA637AU in dip sockets

 

I can ship worldwide. Payment with Paypal or bank transfer in EU, I pay shipping in envelope. If you need the shipment registered you need to pay the shipping.

 

1 couple 25 €
 

DIP socket op amps are 30 € couple

 

Upgrade your sound card or amplifier!

 

PS. I soon get adapters, which allow these to be used to Replace dual dip 8 op amp!

These sound very good to my ears in comparison to ADA4627-1 or OPA827. These have a natural sound with good bass. But remember that these need gain of 5 , at least to be stable. I have a little hiss with such gain with my PPA v2, but the nice sound will make up to it.
