I don't think anyone has done a real comparison of a Galibier to a Raven, at least a Raven One which is more in line price wise with a Gavia.
These mass loaded tables make it difficult to bring over to a buddies and set it up, let alone having the exact same arm, cart and wiring.
I heard a Galibier in a system I had never heard before, and it was a pretty meaningless audition. I heard a Raven AC in another unfamilar system and it told me little about how the table sounded.
I heard the Continum Criteron and Copperhead at the Hi fi show last week on a number of recordings, and on one cut I perhaps got a bit of the essence of how the table performed.
But ultimatley without a really well controlled shootout, a transducer at the head of a signal chain is so reliant on the rest of the chain that comparison other than side to side is made extremely difficult.
Why is it i feel hearing a speaker in an unfamilar room/electronics/front end tells me more about it's performance than a table? Maybe because it's the back end of the chain, or perhaps it's the speaker that give the system a much larger percentage of it's character?
I think many of us are stuck taking a stab at deciding on a table based on cost, size, and hype. I didn't even bother to hear the Raven One at Highwater sound before I ordered. I heard the AC briefly, and read the reviews of it and the One. I needed a compact table that was mass loaded but not too heavy - I realized 100+ lbs was out of the question for me, so I didn't go with Galibier, which was my original plan. Had I lived in a house and had more room, my choice may have been different.
Now once I get my Raven, if someone with a Galibier and a Phantom wants to bring their..... Nah, forget it. I'll save my back in live in ignorance with my blind choice of decks, as you Brits say.
