But I am so keen and smitten by SET that I will first explore it well!
As well you at the very least should do. I recall sharing numerous interesting threads with you in past years. You have extensive experience With a wide variety of Audio components. At this stage it is fair to say that you know what you like and what and what you are seeking.
@verdantaudio gave you some promising SET options, Aries Cerat and KR Kronzilla. Also VIVA Audio PSET 845 I’d mentioned previously. There’s an excellent PSET 845 made in Japan by Triode Corporation. These are big 50 watt per channel mono blocks. I’ve heard them personally and they are splendid! I believe that a top notch SET, PSET or DHT class A push pull amplifier will deliver what you are searching for sonically and musically.
