Purchased a new set of Golden Lion tubes 12AX7.

After about 3 hours of listening all I can say is wow! At first they sounded horrible but after the start of break-in they opened up really well. Now all I need them to do is to settle down in the cymbal taps which sound really bright. And also all the reviews that said they have a warm mid-range...well I would like to have them a little warmer. This tube is very revealing and unforgiving on a bad record. I will continue to break in the tube...after about 50 hours I hope the cymbal taps settle down, and the mids give me that mid-range like I like it, my Sovteks have a great mid-section....more to come.
