So, with my purchase of the new Rega Planar 2, White belt, cork mat, etc, I'm also going to upgrade the op amps in my Joilda JD9 phono stage. Doing my research, most recommended getting (6) Burr Brown OPA 627AP replacements for around $25 bucks each. Well, to my surprise, Burr Brown has been bought by Texas Instruments. But, they do carry the OPA 627 for $27 (inflation, you know). So, I have 6 on the way. I just hope that they are they same specs as the original Burr Brown were. We will see, but my hunch is they HAVE to be better sounding than the cheapo $4 chips that Jolida used, to get to their price point.
