This is exactly why I don't even bother with such tripe. A pre-amplifiers job is exactly that--to pre-amplify. It's not to change the sound, but faithfully render the sound exactly as it is recorded on the source.
So to say that it's best paired with a "romantic" amp is simply ludicrous. (What the heck does "romantic" sound like, anyway?) The gear either faithfully renders the source material, or it does not. And if you want it to add distortion, then just go ahead and say so. But relative to this review, the reviewer is confusing an issue of equalization and added harmonic distortion (which for him, is personal preference) rather than that of simple pre-amplification. I wonder if the author reviews his equalizers as if they were pre-amplifiers? I get the feeling that the reviewer would opt for buying special anti-vibration-stones at $50 a pop to improve his system, rather than moving this loudspeakers to their most optimized and proper room placement (for free).
Why do so many of us actually fall for this snake-oil hogwash?
To me, HP (and his golden ears) comes across as a tweako cultist nut. This reviewer--no different. Most of the "hi-fi" press is nothing more than paid advertisements, yellow journalism, or sheer make-believe quackery. I've always been on Team Aczel anyway.
