LT1792 was state of the art back in 1999, these days you might go with other JFET devices like OPA1642 which is somewhat quicker, lower current consumption and lower distortion. Its also available in dual and quad packages with standard pinouts. The LT1792 is single opamp only and expensive, significantly more than the quad OPA1644...
I'm not looking for a drop in replacement necessarily, rather lowest cost FET devices with technical attributes that best perform some function, and that hopefully translates sonically. My preference has been for bipolar devices though want to try using others.
The OPA828 appears state of art at considerably lower cost than the OPA627, yet the OPA1642 is still much lower cost with considerably lower bandwidth that can still be all that's necessary in some applications.
