Hi Alma,
I have heard 350b's in my Syrah and they are the best, but I cannot afford a pair. I like the 6f6g's a lot and they cost a fraction of the 350b's. I also like the GEC KT66's. Some people don't like them, but they provide a good contrast in sound from the 6f6g's. Where the 6f6g's are dynamic with solid, tight bass, the KT66's are warmer sounding with a warmer bass. I switch back and forth as my mood changes. That is what I love about this preamp!
Enjoy!
