I wonder if anyone here has any experience of this line pre-amp? Since Roger Hebert passed away in 2022 the stock he had ready to go has been sold off and I found a new-in-box Ruby STD at one third the asking price in 2022. Too good a bargain to miss, and I should have it in a couple of weeks. I see his power amps have a lot of fans in the SET forum.
