It is a variable question. Adding a pre, you are adding 3+ more variables(pre itself, interconnect, power cable and fuse). It is certainly more fun but it is going to cost you more. Would it sound better--> theoretically Yes but practically, it is going to depend on how u choose to put on your variables. Always remember this, never go lower level than your current status, otherwise it is like a sports car put a economy tires. Hopes that help.
Wadia S7i direct to amp
Looking at simplifying my system, wondering if anyone has heard the new Wadia S7i direct into an amp, and if so, how did the pre section fare? My experience w/ an 860x years ago was that the pre wasn't good enough for me to get rid of my pre at the time (a Cary SLP98).
