The SL 1200 G/GAE is is every bit as good as I and others have stated. It is far beyond anything I've heard from VPI although I've not heard the VPI DD. Much as I love my Kuzma 4 Point and I'm buying an Airline I prefer the GAE to the Xl DC which I had a nice session with.
The TW's sound dark to me but that is not necessarily a bad thing. Different systems, different likes. I'm not saying that it's as good as a Caliburn although I have no idea why Mr. Fremer would choose that messed up record with a collection so vast. I definitely could hear the superior timeline of the GAE and I could definitely hear the superior decay and body of the Caliburn. Like I've written before, remove that horrible rubber mat and the GAE takes on a whole new character for the better.
The stock mat is horrid and sucks life and light from the sound.
I have a buddy with a +20k TT and a Triplanar with a very expensive cartridge and it will not touch the GAE for corporeal real-ness. The turntable belonging to my friend is a DD and so the timing is nearly perfect as is the GAE.
Again, it sounds like my SP10mk 3 NG only less grand. Like a Steinway Parlor Grand compared to a Concert Grand.
i did recently have a $10k phono stage which was superb connected to the GAE. It is the third best stage I've heard. I didn't buy it because in the end, although I absolutely loved the aesthetic, it was bested to my and my gf's ears by the iPhono 2 + linear PS. Now, it was close enough that I could very very easily see the choice coming down to personal taste.
