I’ve been running a Classe Audio Thirty preamp in balanced mode for many years. Given it was made in the early 90s you should be able to pick one up for a few hundred now. In addition to balanced out it has one balanced input plus RCA inputs labeled tuner, cd, video, and phono/aux. The phono/aux input on mine is used as aux as I have no turntable. Jumpers are included with it so you can switch it back to phono. I have a Schiit Modius on order so I can take advantage of its balanced input. While some have described it as mildly dark I have always found the Thirty to be very neutral. It’s the reason I’ve used it for so long.
