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.
I am another FS owner (deluxe mkII) who is able to comfortably endorse them. They are dynamic,detailed, tonally "right",articulate, refined and nuetral(subject to tube rolling). I have compared to AR refI, and FS was in all ways better--sorry no Wytech Labs. Also do not be fooled by "modest" deluxe mkII--it is no slouch and does not necessitate a higher FS model. Build quality is supurb and mine has not failed at all in 4 years (bought used)

I am sure you will not be disapointed, although previous comments in regard to impact of amp and speakers on the qualities you value are most appropriate. I run mine with high power s/s amp and efficient speakers to get just what you speak of.
