"Which means more neutral more natural or more real? Honestly, more "modern" means exactly what? I'm familiar with the term "neutral" which I am still trying to come to "terms" with over all these years but "modern"? what exactly is that?"
You answered the question yourself.
"Haven't heard the Rogue but am familiar with all the current Quicksilver preamplifiers. While I am a big fan of their amplifiers, less so of their preamplifiers as they impart too much of a "signature" on the musical presentation IME, too rich sounding would sum it up for me."
There's a definition of a classic sound. A more modern sound is less of the above qualities, and more neutrality.
You need to take your meds. You're getting too wound up over such a small matter.
