I lusted after the Phase Linear 400 in my college years and now, years later, I bought and still have it. Nothing spells 70's power like the Phase Linears. The big meters are intimidating....intimidating and impressive!! I took it to the last Carverfest and had the pleasure of Mr. Carver wanting to hear it in our cabin system. As I sat beside him and we listened to music on the system, he told me how he was just a kid when he designed the amp, and that despite all the amps he has made, he did not think he improved much over the original Phase Linear for sound quality. Thats pretty impressive in my book considering the other equipment he has built and listened to. I don't have it in my current system (TFM-55), but the autographed Phase Linear and the memory of that experience are enough to last me as far as Carver equipment goes. Yep...you could say it's my favorite.
