If you want to try tubes, I would look at Atma-Sphere.
But, if you want to try the Doshi, then you could get some rca-xlr convertors from Jensen for about $300. I spoke with Ralph (Atma-Sphere) and he said they shouldn't do much to the sound- I was thinking of using them when I bought his amps).
I would then look for a pair of Zero Autoformers to help with the 4 ohm response of your speakers.
Hopefully, Ralph will see this post and give you the most accurate information.
