After playing with the pieces I would like to suggest something to you. I would suggest you get a purcell or aanother upsampler, ( they are making a new one for the Scarlotti to be available sometime in the future) and try it with the scarlotti at 176.4 with dual AES/EBU cables. We did it this weekend and used a pair of Odin balanced cables as the digital cables. After we finished I tried plugging the dac into a Quantum X4 Nordost "magic box" and the results were something very special. I know you like the stack but this just takes it over the edge for me.
I am a dealer for this so I am not trying to sell anything just reporting my findings on what I believe to be very significant and special. I only wish I could afford one and that everyone that listens to digital could have the opportunity to hear what is possible!
