I have the newer Muse (the model 296) and it is unbelievably good. It seems to me if you can get a used model 2 (make sure it has the besel filter option which is VERY important and HDCD - if you have HDCDs) or a model 2+ (the same thing but with all the options). The MSBs are not nearly as well built or designed and Muse digital gear has a palpability like analogue. The 2+ was a reference quality DAC 4 years ago, the MSB never was nor will be. Now if you could afford a good deal on a Model 296 ($1250- $1500) you'd really be in heaven.
Good Luck.
