Dahlquist DQ10: what is best way to power?

Without knowing the budget, here's a few. A vintage belles, or hafler would be nice. Nakamichi PA7 would be high on my list. If I had them, I think a belles 400 would be my first choice. I think it would be cool to pair them with something from roughly the same period. Threshold would be another great choice.

In their day, they sounded great with a Bedini Class A amp. The more power the better. For class A/B I would look for 200 wpc.

I had a buddy who ran them a Bedini Class A , one hell of an amp.

These were my first speakers and I ran a McIntosh 2205 stereo amp (200 plus watts a side). I could have used more power. Get the biggest high current amp you can afford.

Back in the early 1980s I heard a Bedini 25/25 pure class A amp driving Dahlquist DQ-10's and Quad ESL-63's. This was an A/B listening session for both pairs of speakers; the Bedini was competing against Levinson mono blocks. The Bedini acquitted itself quite nicely with both the DQ-10's and the ESL-63's. I certainly agree with Schubert - "One hell of an amp."
