Amps build around a higher powered 300B-XLS tube, or the 520B (which is another higher powered 300B type tube) will get you around 24Watts or so. My amp which is Art Audio Jota 300B SET is an example of that design. It worked spectacularly well with speakers such as Tannoy Definition (89db) and now Fyne Audio F703 (94db) while providing the SET magical pure class A amplification.
Is there a 300B type amp out there with some WATTS behind it?
I recently acquired a Feliks Audio Arioso 300B amp. To put it simply, it is incredible. I understand one way to tackle the issue of using SET amps is with high sensitivity speakers. Is there a 300B or something that gives you that same sound out there with power so you have more speaker options?
