Tim,
I respect your option to prefer what you call "more accurate reproduction". As, according to my standards, it contains less information and is less enjoyable than the sound reproduction I prefer, I can not call it as more accurate - only "instrumentally more accurate". Anyway I would love to know from you about the Canadian and Harman electronics tests - I hope you are not extrapolating from the loudspeaker research and development to the electronics.
Curious to refer to the long term and tiresome of some types of reproduction - it is just what the audiophiles typically have against " "instrumentally accurate" reproduction. It is also a big sales argument of highend - I am now quoting Nelson Pass (my bold) : "Our real customers care most about the experience they get when they sit down to listen to their music. We create amplifiers that we like to listen to, on the assumption that we share similar taste. We want our products to invite you to listen. We want you to enjoy the experience so much that you go through your entire record collection - again and again. This, by the way, is a very strong indicator."
You are a happy man - most people dream of owning a XLF. You found a perfect reason no to own it no one can dispute - you would tire of it quickly. Typical audiophiles are supposed to get tired after five years - the time to developed and market an improved version!
And yes, we have been here before.
Of course I am. That research indicated that a strong (overwhelming?) majority of listeners -- trained and untrained, audiophile and otherwise -- prefered a more linear in-room response. The likelihood of obtaining a more linear in-room response surely diminishes with less linear electronics?
