There is likely no technical reason why they are not a good match.
Whether one likes the results is a different story. If one likes Shindo then most likely more Shindo or similar tube amp will be preferred.
And of course the speakers used will be a big factor in what amp combo works best.
I use bc ref1000m amps with speakers that area good technical match and with arc tube preamp that is a similar good match on paper with the amp and the sound and performance is top notch imho. My speakers are not particularly tube amp friendly so that is pretty much that. My main rig is built around the speakers not the amp. Others might go about things differently of course and end up in a totally different but great sounding place. Ymmv as noted.
