Based on updated technology of the late Les Sage of Sage Audio Electronics, the Ultra Analog THE-1 must be the world's highest performance OP AMP.
The Ultra Analog UA-THE1-DIL8/S module has one THE-1 soldered onto a 8 pin DIL adaptor. Can be used to replace a DIL NE5534 or OPA627/637.
Why not upgrade the DAC buffers in your CD player?
Just look at these specs:
- THD+N less than 0.00001%
- Slew rate 25V/Us
- Ultra Low noise - more than 5 x lower than the OPA627
