Edison 300B Amp

I have a Paramour amplifier that uses a 2A3 in a parafeed circuit. It is capable of significantly more bass than the Zen, and it is a lot less sensitive to the loudspeaker load than the Zen. The Paramour amp provides flat response and reasonable power for a 2A3 SET, definitely more output than the Zen. That said, the Zen sounds really good, particularly in the midrange. It's a great value too, in my opinion.
