Looking for an incredibly dynamic preamplifier


I'm looking for a dynamic preamp that provides plenty of attack, great bottom end, and an iron-fisted grip on the system. The best I've heard so far (and by a long shot) is the Wyetech Labs Opal.
I would assume that other units with robust outboard power supplies are good candidates? Maybe a battery-powered unit like the new DartZeel pre would qualify?
Thanks.

Again, need you a 5th recomendation FIRST SOUND after multi others the best yet.
I also 6th the First sound as a preamp.Dynamics are tyed to the amp as well, but your grounding scheme has a huge impact on it.I love the tone and timbre of the FS and you get to roll tubes in it as well!! Good luck on the hunt Dennis
Wow; it's almost unanimous.
First Sound has always interested me but no one sells them anywhere near me and I've never actually heard one.
There seems to be a huge price difference between the Presence Deluxe and the Paramount (4k vs. 16k?).
I'll search that archives to see if someone can tell me the sonic differences.
Have any of you directly compared any of the First Sound products to any of the Wyetech products?
Thanks.
