I had first generation Elrogs a few years ago that were exceptionally good sounding but unfortunately unreliable.  That's all been resolved now. The current production versions you have are likely an improvement In sound so they are superb I'm sure. Must sound exquisite hearing the new  Elrogs  via the Nenuphar. Surely a different sonic presentation versus the Enleum.

Any suggestions?

@rwpollock   I'd look to @charles1dad  and @larryi and others who are advanced and experienced in the area of tube amplification. 

I really like, with almost any reasonably efficient speakers, and some not so efficient, the Synthesis A-40 integrated amp (digital dac included). It utilizes KtT-66 tubes in pushpull to deliver 40 wpc.  If you demand more power their A-100 amp delivers 1000 wpc by doubling the number of output tubes.

I would also hazard a guess that an Audio Note Oto would work well.
