I second Jfrech recommendation concerning the addition of a tube preamp. I use a CJ premier 16ls (tube) and a mf 2500 amp (ss) and find the music to very open/air with a large soundstage. The remaining part of my system consists of Thiel 3.6's, audioquest cables, and scd-1.You might want to consider either a Cary or Blue Circle preamp. Although I am not sure either of them have balance connectors. I am also wondering why you are running both EMC-1 and SCD-1? Also how do you like you Pass X-350?
Pre-amp questions for SCD-1 & EMC-1
As of this moment I am using a Theta Casablanca as my processor for my Sony SCD-1, and EMC-1. The amp is a Pass Labs X350. Would taking out the Casablanca and opting for a pre-amp improve my sound quality. If so how much of a change should I expect. My second question is what pre-amp do you recommend? I would love to use the XLR connections on both of these players, so if you could please recommend pre-amps w/ balanced connections.
