Preamp w/ big sound AND extended frequencies ?

Any of the Suprateks meet these goals.

First Sound preamps--from the cheapest to most elaborate--give a really big, thundering sound. And great extension as well. Soundstage did a glowing review of the Presence Deluxe a few years back. I don't remember if they're available with phono sections, though. I didn't order mine with one.

Second Lugnut. I love my old cj pv11 phono output but it just cannot match the supratek, ESPECIALLY at the high extreme AND the supratek can hang with that CJ midrange.
