Obviously, if you take high end to be mean high quality, and not merely price. If you’ve only ever been listening to 128kps MP3 files through low quality headphones your experience will be limited and can only be valid for yourself. It can hardly be relevant to anyone else if that’s all you have as a reference.
I love hearing from people who have years of experience in high end audio. It’s even better when they tell you that although x costs only 10% of y, it actually sounds just as good, or even better! It’s the worst form of heresy in some circles I know, but it’s great when it happens.
An honest owners opinion can also give you a better idea of what living with a pair of Wilson speakers, McIntosh amp, Grado woodies etc might be like. It’s a great leveller when owners sometimes post less than flattering reviews. How dare they!
However, one major problem with reviews I think, is often one of communication. Words are a notoriously slippery way of conveying sensations. And then there’s issues of hearing capability, individual bias, and last but certainly not least, vested financial interests. And even if they’re bring honest, not everyone will always know themself inside out that well. Sometimes not even after a lifetime alas.
We know HiFi shows set in hotels aren’t always the best place to hear great sound but it’s not impossible. I one heard some Avantgarde Trios near as damn it bringing back to life (via vinyl) some long, long dead jazz musicians. Almost spooky, like that cowboy scene in Poltergeist.
So it’s either the reviews or we go back to shows and the dealers, and back to listening for ourselves. It’s far from an easy life being an audiophile unless you’re the audiophiliac himself, Steve Gutenberg!
