I’ve played out my 300B tube odyssey now and have decided that they are all good in particular areas, so I will be keeping one pair of each. That does, however, leave me with a spare pair of the overall best of the bunch, the Gold Lion PX-300B’s. Loads of great reviews out there for these.
I bought these as a matched pair from a UK supplier (Icon Audio) 3 weeks ago and they have never been used.
I am asking £200 delivered, which is a pretty good deal.
