Hi Ehien,It seem's that I'm not the only one playing with op-amp in phono stage these days. I first try NE5532 as input and OPA2604 as output. Then change the 5532 for an OPA2134. Then split the input for two OPA134. Change the 2604 to 2134. Put back the 2604. Change the 2604 for an AD826. The AD826 is clearly above all those. I still have some LT1364 to try as output amp.
This takes me more than an year. Right now, I'm comparing OPA134 to OPA227 to LT1115 for the input stage. After I settle on one of them, I'll do a match between it and the OPA627. I can't use OPA637 because at HF, the gain go under 5, so instability can happend.
Regards,
Daniel Trudeau
