I need to get suggestions on a high gain phono pre

I'd also suggest you check into the Art Audio Vinyl 1 - tubes with step-up transformers. Occasionally, you can find one used. It is a great unit. Good luck.

I suggest you check out the Aesthetix IO. Tube from front to back and can be as high in gain as you would ever need with great sonics and very low noise. You didn't mention a budget but a used basic IO can be had for around $2500, a good bargain in high end phono stages.

I really enjoy my Herron. If I was to change out, I would consider The Groove. It is not tube, but has a great reputation fo accuracy.

I've owned a lot of phono preamps over the years and have been using an EAR 834P for the last five years or so. If you like tube phono stages this is one you should give a try. Easily one of the best buys out there if not the most cosmetically exciting (unless you go for the chrome faceplate). Dead quiet, dynamic, and very musical. I've spent a lot more and not been as happy.

A note on Tom Evans 'The Groove.' I know someone who has been importing these and the Vibe preamp. He says there are some quality control issues. And they are grossly overpriced for what you get. Just what I heard. I have no personal experience. Obviously the Absolute Sound thinks highly of them.

Have to ask why you got rid of the Herron? Agree with G_m_c, it's a great unit.
