Esoteric DV50 or SA60 for 2 channel audio ?

Some say the 50 is better...what is the real deal ? I do like the 50 but don't have access to a 60 other than buying it.
The one thing difference that I am aware of is that the SA60 has a newer design transport. They supposedly improved the clamping mechanism and made it much smoother.
So I would say that it will sound better. IMHO of course
