Does anyone on this Forum have any experience with Audio research ref 610t monoblocks


Good afternoon. 
I have a chance to pick up a set of very nice Audio research ref 610t monoblocks . I believe there rated at 600 wpc, class A, or A/B, not sure. I think they use around 16-20 tubes. It’s a older amp, older technology. But in the 70s they sold for around 40k for the set. Anyways, I wanted to know if anyone here on the board has a pair, has heard them, and get your honest opinion. How do they sound? Are they noisy? 
How would you compare them say to a Prima Luna,, etc, etc. I know they are super heavy, I think 170 pounds each . And the tubes can be expensive. But I’m trying to find some people that can tell me there experience with these amps. Thank you

I heard the 610T amps in a biamped system in a dedicated room. The gentleman was powering the midrange/tweeter of a pair of apogee diva panel speakers, he was using krell FPB 750 MCX monoblocks for the bass panels, and an arc preamp. The sound was excellent. He also had to figure out how much heat the system was going to put out into the room so the proper central air unit could be used.
