Preamp Suggestion

Now I would like to buy a new preamp to replace my ARC Ls7, My choose is ARC Ls25 or CAT Mk3, Can anybody can give me suggest about the performance and the price, which is a best value
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 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.
