Well, just goes to show - the only way to know whether or not you'll like a piece of hifi equipment is if you listen to it yourself.
rob, what sort of electronics are you running the Sigs on? I suspect they're fairly high-end (at least), no? Going by your reply, I'm pretty sure the fault at my demo of the Sigs was the upstream electronics. I realise they're very up-market speakers and the CDp/amp I was running them on were no match.
The reason I suspect it's that, and not just differing tastes, is because I too found the B&W 1NT's very appealing. The treble was sublime, and as long as they were paired up with a suitably serious amplifier, the rest of the sound was equally sublime. They sounded rather soft, muddy, and uncontrolled in the bass when used with a mid-level amp, and they only sounded their best when I heard them hooked up to one of those scary huge American power amps (with a Linn Ikemi CD player).
Also, the sound of the Sigs that I experienced was nothing (and I mean *nothing*) like the Future floorstanders I listened to later on. I would imagine the Sigs sound something akin to that (sweet, refined, detailed, delicate) when paired up with the right equipment.
In any case, the moral of the story is to take everything you read on this (or any other) forum with a grain of salt!
BTW, you still haven't told us what model you're referring to...
Cheers,
Dunc
