I am thinking of getting a Ref 50 to replace my Pioneer VSX 49 TX and would like any feedback on a possible upgrade. Right now I use the Pioneer as a preamp with a B&K Reference 7270, I have the full Paradigm studio setup including studio 40's 20's adp's cc, and servo 15. I was just wondering what differences I might hear if any. Please let me know what you think any pros or cons. I must make a decision by 3:00 tomorrow afternoon. Thanks to any and all who reply.
