Tweaking Cary SLP-98P F1 Preamp


As you know for SLP-98, the F1 mod is a significant improvement over the standard. I just bought one used and the stock 6SN7 tubes that come with it are horrible. So, I am waiting for WE6SN7 tubes for it. Until it arrives I want to ask people with experience with F1. I have Pass X350.5 amp driving Soundlab ESL speakers.

1. How good can it get with best tubes?
2. Some have recommended using NOS 6f8g/adapter instead of 6SN7, any thoughts?
3. After getting the best tubes, is it still worth it to direct-couple it? It is supposed to improve bass, dynamics....

I have a Cary SLP-98 F1 in my big system. I have not rolled any tubes yet. It's not the last word in pre-amps but it is still a very good pre-amp with some musical leanings. It should work well in your system but if you are looking for more accuracy and perhaps more detail a top of the line Audio Research will push you in that direction. I personally like the sound of my SLP-98 and don't have any plans to replace it.
