I have a sp 16 that I have owned for a bit now. I have tried RCA 3mica 5751, EH 12ax7, ( did not like at all ) and currently using Tung-Sol vintage from 1959 for about 2 years. I keep getting the upgrade itch so I am going to swap tubes. Any suggestions on what to try next? I keep reading good things about the gold lion's so i was starting to lean towards that but, I am not dead set on anything. What do you suggest to try next? I like a bit warmer sound but, I like a faster top end. The RCA 3mica had a nice bloom but, I did not care for the top on this preamp. Just was not a good match. Im not sure if the pre just likes the higher output of the 12ax7 or what but, from what a lot of people raved about that tube, I did not hear on my preamp
