I haven't heard the syncromesh but like all of Steve's products will be good. I don't know if it is better or worse than the AP2. People who own one tell me Steve is spot on when he says its about 90-95% the performance of the Off-Ramp which would put it about the same as the AP2.
I don't know the EE DAC although guys whose ears I trust speak highly of it. I own the M51 and I give it a slight edge over the Metrum. It has a more natural sound - but its a personal preference thing - some describe it like putting a blanket over your speakers and knowing the particular DAC people who said that were comparing it to (a PDX) I understand the comment - the PDX is a very dynamic, forward and in your face DAC - clearly better than the M51 (also twice the price) but for some its a bit too much describing the PDX like ultra violence - but to my ears the PDX is simply more real.
Thanks
Bill
