Thanks very much for that information. I don’t "need" a preamp but I really want that F360. First, I am a Jim Fosgate fan and highly respect his engineering skills and passion. Now that he is gone that pre will be likely his last design. Next, I love the features with the balanced connections and all the knobs to "diddle" with the sound as Zeos says. I could drop that unit into my desktop system so all those knobs are right at my fingertips and would add rear speakers to get quad. Or, I could drop it in my main system. The price is so reasonable for what you get IMO. I see tube preamps going for $$$. The idea of running both a digital and an analog surround system side by side is VERY appealing.
Does the F360 hold its own with the BAT (I think the BAT is around $10K right)
I have an Onkyo 9 channel receiver circa 2019 in the mancave and love it. That company is all about quality and convenience.
BTW, your room looks great. Have you thought about adding some room treatments to your ceiling? From the pic it looks a bit like a hard surface.
