Looking to upgrade. Need 8-12 WPC.. Really enjoying a Sun Audio 300BE as my first SET experience but wondering where to go next?
Had one for a few years and it is a very good value amp.I love my JJ 322 300B SET amplifier, which produces about 20 watts per channel using a paralleled pair of 300Bs. For driving my Quad ESL 2905s, it beat every amplifier i have tried over 5 years, including very pricey tube and solid state ones. Best of all, I got it for around 2 grand from The Music Room with new tubes. Steal of the century. If you see a used version, pounce. It’s a beast, about 95 pounds. Looks nice too.
Criticism via faint praise?Had one for a few years and it is a very good value amp.
Jeffery Jackson made a beautiful 421a amp. Great sounding if you can get away with the output. Not a problem with our horns at all. The 45 is still hard to beat.Over the last 6 months, I’ve explored a range of SET amplification and find in my experience the “best” SET amplifiers are ones that don’t use 300Bs. Don’t get me wrong: 300Bs are indeed lovely and a bit lush sounding, but my favorite SET amps are those that use the 45 tube or the even more esoteric Western Electric 421a tube. There’s no free lunch: you have to give up quite a bit of power, and I realize this is probably unacceptable to you. I use a Klipsch La Scala horn speaker, and even a 1 watt SET is plenty.
So, my current favorite SET is the Oliver Sayes 421a, which is a model of simplicity. One 421a power tube drives both channels at 3 watts. One 6SL7 driver and one 5BY rectifier. The NOS Western Electric 421a is not as pricey as the 300B, but to my ears, sounds even better. But half the power.
