TUBE AMPS-CARY, BAT or VTL


I originally posted this question in the wrong forum... So, I am re-posting it. I am looking to add a tube amp to my system. My finalists include:

Cary Audio CAD 120-S
BAT VK55
VTL-150

The rest of my system consists of Prima Luna Prologue 8 CDP, Dodd Audio Preamp, and the Salk SongTower speakers (with the LCY ribbon tweeter). Has anyone auditioned any or all of these amps? I would love to hear your impressions of each unit. Thanks in advance for your responses.
