Is all the hype warranted

@OP. There are other USA made affordable tube amps to consider such as Rogue audio. Despite your loudspeakers' relative efficiency, you might want more than forty watts per channel in your quite large room. SETs definitely need not apply unless all you want to listen to is harmonic distortion.

@yoyoyaya your comment about harmonic distortion may apply to some very low powered SET amps with mis-matched speakers but it certainly doesn't apply to the majority of SET amps. Certainly not the one I listen to daily. It would be the equivalent of describing non-SET vacuum tube amps as "unless all you want to listen to is varying degrees of negative feedback". 

...probably not, but loud noises tend to draw attentions.....which are, thankfully short...;)

That's kinda what I thought, but after talking to them it seems that they have had a consistent 2yr wait for some time.  Not just hype evidently.
