what is the best Kt88 to get

I just found a NIB quad of Gold Lion that I had picked up a while back and forgot I had them in storage.   I just put them in my Quicksilver Mid Monos.   I had a quad of these a few years ago but didn't like how they sounded with my speaker at the time.  They are a great sounding tube in the right system.  Plenty of power and huge dynamic sound with my Heresy III.

I have had good luck with Gold Lion.  I can't even tell you how old the ones I'm using are....they are a back up quad and they still match very closely.   I have had other type GL like 66 and 77 and they didn't last nearly as long
