Boeing,
I wish I could say that i have compared them. I have never had that opportunity. However, Jeff Fritz has at Ultraaudio. Based on the reviews i have read, i believe he would order them (for his system) as follows:
1 Gryphon Colosseum
2 Boulder 2060
3 Vitus Ref (the 50-watt amp)
4 Gryphon Antileon Signature
Essentially, his in-house reference went from the Antileon to Vitus to Boulder 2060 to Colosseum. He has since moved on in 2012.
Try reading Jeff's reviews of the Vitus, Boulder and Colosseum. Ultraaudio.com Hope that is helpful. Good luck!
