New OpAmps don’t like Pink Floyd

Stew

I feel really stupid after a discovery I made recently. When I pulled the AD826's due to oscillation I noticed a capacitor between two of the opamps bent over with one lead close to, but not touching, a resistor lead. I straightened it and didn't give it a second thought. The next time I changed opamps I started wondering if the leads were close enough to cause the oscillation problem. I put the AD826's back in and No Oscillation!

My CDP has four opamps (Two balanced to unbalanced converters and two output buffers). The AD826's are the clear winners for the balanced to unbalanced converters but I'm still searching for the right output buffers.
I like the dynamics of the AD826 and the bass and mids are great but the highs are a little sharp. The AD823's have the best mids and vocals I've heard. Unfortunately upper mids and highs are overemphasized and lower mids and bass are lacking.

I'm considering AD843's or OPA627's with brown dog converters. Wasn't there someone on this forum that was selling OPA627 assemblies at one time?
