Front end is CRITICAL. I recently bought a pair of older PSB towers (Image T-65) for $400 on Craigslist, along with the rest of the speakers to complete the surround setup. I bought them to use in my new house (we are moving in a few weeks). For the time being, I hooked them up to my music system right next to my Sonus Faber Cremona towers. They sound surprisingly good... I was taken back quite a bit. And I realized something that I had always been told by my dealer.... SOURCE IS CRITICAL. Whatever your source is: vinyl, CD, digital files, reel-to-reel, etc., that is where it starts. So as I listened to these speakers, amazed, and I realized that there was about $15,000 in front of them. Just goes to show IMHO, how important the source is.
