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

"How would you compare them say to a Prima Luna"

Get real! It appears you’re new to tube amps?

That level of ARC and a value MIC tube amp shouldn’t be in the same sentence, with exception of equal build quality.

Both amps hooked up to same setup at low volume will sound good,and you can nit pick what the ARC does "better". Start bumping the volume-game over, ARC pulls away effortlessly.

It would be helpful to know,

1)What is your rest of the system?

2) What is the service history on 610T’s?

You started a thread asking the community for preamp recommendations on July 31,

“Looking for a reference preamp with XLR inputs and outputs. Looking to spend less than 10k, no tubes.”

I wouldn’t dare pick up 610T’s unless you’re planning to add ARC preamp. This is the only way to fully enjoy ARC house sound. Even then, I would gravitate towards a newer ARC amp.

PS: Don’t forget to factor in the ‘heat’ from 610T :-)

Unless you absolutely need that many tube watts, I would stay away. Heat, tube replacement cost, size, potential service issues, ugly etc. 

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.

Lalitk, 

I don’t have one specific system as some. I have a pair of Magico s3 mk2 speakers , boulder Hercules amp, a couple of dedicated dacs, Also a pair of La scala speakers that I already have a Prima Luna amp and Preamp, as well as a pair of Atc 50s. I wasn’t aware that we are only allowed to have one system to be able to discuss audio equipment. My bad. Before I buy or add something to my collection of gear I’d like to ask around . Thank you for your input , much appreciated. I just acquired a Benchmark La4 after all the good feedback for a neutral preamp. Thank all for your recommendations.
