It all depends on what you are looking for. Do you want to avoid distortion and coloration or are you going to use your preamp as a "tone control." Take a look at our website at http://placetteaudio.com. We have replaced a lot of Cat's and even a couple of AR ref 1's because once you hear the clarity that is actually possible with properly used Vishay resistors, you can never go back to anything less.
