I even had a bass player sit down and I asked him which snare sounded better, it was just pre vs. pre no compression or eq, he instantly picked the snare recorded with the Eureka.
This sentence is funny...if you're not a bass player!

OK maybe it wasn't meant as a joke but it reads like one..."even the bass player heard it!"...haha
HapiCmpur, you asked
Are there certain specs to look for? How much do you have to spend these days to get a "good" mic preamp? And's what's the likelihood that I could do appreciably better than my Yamaha's preamps without spending a bundle?
The specs on your Yamaha probably look pretty good on paper so don't be fooled by specs. You really need to use your ears. How much you have to spend is subjective, and depends on what you already own and if you like the sound of it or not. Without spending a bundle is hard to answer, not knowing what a "bundle" is in your mind. Many guys are willing to slap $1,000 per channel down to hear the difference and don't consider it to be a lot of jack, other guys squeal about having to spend more than $200.
Jonnyc loves the Eureka, a $500-ish box. In my opinion it's "ok" and certainly a step up or three from a cheap mixer's preamps, Presonus does pretty well in the bang for the buck department most times.
A Rane MS1B might be a step up in quality for you, at $150-ish it ain't bad. I personally think it's better suited to acoustic type sources than vocals etc but it's definitely decent.
The problem with preamps is you never know what's out there until you put it side by side with your own. Even then, you may only experience small differences. The GT Brick might put a smile on your face, in a totally different way than the Rane or Presonus though.
