Clear Winner of my comparison review
by Noam Bronstein
I recently reviewed the whole fleet of 300B tubes. The Genalex Gold Lion PX300B won - it ranked #1 in 7 out of my 8 music tests, using two single-ended amps. This tube is detailed, musical and just consistently a joy to listen to. It basically does everything "right". For my full review see my website, www.wallofsound.ca
