I haven't read Dan's article on the subject but I will. The thing about cheap and or bad sounding pre's is that distortion,lack of speed and wacky peaks in response all add up when you've got 20-some tracks being recorded. The poor performance of the pre has a cumulative effect. If you use a clean pre amp with great transient response that is mostly pretty flat, the LACK of problems add up too, {this is good}. Most folks try to keep a variety of pre's and mic's around to shape instruments and vocals on the way to tape without having to lean on using EQ so much.So the average pro studio will have pre's that lean toward being colorless, pre's that sound very aggressive in the midrange,pre's that have sparkle on the top end and every thing in between. Then, there are mic's. this is a huge deal also. mic's,some argue, are a bigger deal than pre's. All I mean by this is some folks will use the pre's in their console and use mic's to shape things. Over time, with a larger variety of pre amps available,people are using certain combinations of mic's and pre's to record certain things. It can take a long time {many years} to come to conclusions about what works on what. This, in fact ,is something we never stop learning.
So, I guess the answer to your question is, you would have to get a Viper and try it on a bunch of different things to know where it fits and doesn't fit.
The biggest thing that effects how things sit in a mix is arrangement.IMO. Having said that,it sure is nice to have a bunch of mic's and pre's that sound great but different to help collect any given sound in the most flattering way..
I'm off to gig for a few weeks. This place rules and I'll miss it. I'll try to find a computer so I can read along..
