I have recently acquired a Prima Luna Prologue Three preamp. I sm real pleased with the sound quality. My amp is a solid state MCA 20 Anthem. I have wondered if I went to Tube in my amp as well as the preamp would I enhance the sound even more. Two sources that I have relied on in the past have come up with opposite opinions. One says B&W is really not suited to Tubes. The other has said B&W was made for Tubes. I would like to hear what you experts have to say to a neophite in the field. Thanks in advance for your help.
