John,
I'm well aware that speakers are system dependent and that a change in the electronics, cables, etc. could have a noticeable effect on their output. But I'm not writing a full-scale review here; I'm stating an opinion based on first hand experience at an audio show. And I was very upfront about that. Anyone reading my comment would know that it was based on a one-time experience at a show and naturally a change in the electronics "might" change the perception. But I don't have the luxury of doing that kind of thing nor the time. Sometimes we have to make decisions based on the experiences we have and that's all we can do.
You said: "When we hear something that is just not "right", a lot of time and effort must take place to determine the cause. There could be multiple reasons for this....including our personal preferences."
That's pretty obvious John. I'm not interested though in checking out the bad link in a causal chain. I'm interested in assessing a pair of speakers in a limited amount of time and then maybe making a purchase. And just as obviously this will have everything to do with personal preferences. Our ears are not the same. You don't have objectivity here; you have a set of very subjective experiences and people use those to make decisions about audiophile investments.
That said, I find B & W's top of the line signature and nautilus range to be right up with JM Labs as my favorite speakers for the music I like to listen to. The Signature 800 is probably my favorite speaker of all. And the Dynaudio line, which I tried very much to like as well, I don't care for at all--too rolled off in the top end. So yes, this is all a very personal, very private set of reactions, but ones that I wanted to share with the person who set up this thread. He asked. I responded. That's it.
