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 :-)
