Topping Pre90 Switching op amps?

I have found that the pre90, in my system, renders many recordings beautifully transparent and many other recordings thin and brittle. It seems that swapping op amps might be a solution. Has anyone done this? If so kindly report on your experience.

If you want the sound of the pre90 without the hassle, then the Benchmark LA4 is the best bet.

True but the price differential was unacceptable.  (I needed 3, now 4.)

Nota bene:  The OP was asking about swapping op-amps in the Pre90, not amps to connect to the Pre90.

It is I and I really wonder about adding a "tube buffer" to the Topping.  Seems counterproductive.
