I have one of the new Zen TORII MK5 amps, that I went and picked up in person back in November of 2021, I originally ordered the MK4 and they had just come out with the MK5 so I instead got the MK5 from Steve, I only waited 11 months for the amp at that time.
It is a great amp, and I converse with Steve about different tubes all the time and he has been very helpful with choosing the tubes I use.
Their amps are definitely worth the wait and I will end up giving mine to my son when I can no longer enjoy listening to music (20 to 30 years hopefully).
