I agree that it is easy to make the LCD-2 sound good, as there are many testimonials regarding portable gear and modest desktop solutions that make the LCD-2 a joy to listen to. I also agree that the LCD-2 does scale. For myself it scales very well with better amps, and it reportedly does very with balanced amps like an SR71B, my WA22, or the Apache. As the LCD-2 also reflects the differences in tube types, it's not a stretch to say that it will scale well with better sources; many have reported that it does.
Lol, a Zappa reference. I would have to say that megalomaniacal comments aside, just because someone doesn't articulate well with detailed impressions or full-blown reviews doesn't mean that they can't hear their gear. These are two different skill sets.
Another skill is presenting one's opinion without patronizing, condescension, or outright braggadocio regarding the level of monetary investment one has made. Many of us fall short on some or all of these points from time to time myself included, but googleli does have a tendency to take that road a little more often than most and IMO that is the source of much of this friction.
