Tektron offers quite a range. Besides 2A3 and 300b they have a 211 tube integrated amplifier. This is pretty unique. Of course they have a plethora of  non DHT pentode type el 34, KT 88,KT 150,6550 models. etc.

My Backert preamp is an original Rhythm, the 1.1 (they now sell a 1.3 version). There is a used 1.1 for sale now on Audiogon for $3500. The only thing I don't care for is that the Backerts invert polarity/phase so you have to reverse the red/black speaker connections. No big deal if you don't switch you gear around. That said, it's fairly easy to tell if things are inverted; it is kind of like pushing your music uphill....

For those looking for a preamp to go with First Watt etc. you might take a look at the Allegri Reference by Townshend Audio. Its a high quality passive design.
So curious about these expensive and exotic single driver speakers. I have a pair of omega alnico towers with matching 10” subs and love them, but have never heard magus or nenuphars. The omegas have a paper hemp cone with whizzed.
Anybody heard these next to the omegas? Wonder how much you get for the extra bucks. With dual subs, I’m out just a little over $4k for the omegas with teak veneer.
