total heresy and I have been thoroughly insulted hated and put down for it but I use two preamps. the very first time the hatred was like a tsunami of vile responses. Since then I have come to regard two preamps as my signature (with a big kiss my === to the haters,) . if you cant get past the use of two devices together, then you clearly live in specs and theory, and not actually listening.. is my take on it.
Anyway yes i use two preamps. I own a pile of them, and use two together at all times.
Usually the Byrston BP-26 and a Threshold FET TEN' or the BP-26 and a ARC Sp-15 or the BP26 and a VAC Standard,or the BP26 and an Audible Illusionsorthe BP-26 and a Conrad Johnson Act 2
It solves the too much gain with two vol controls. and sounds great.
