The sound is clear and soft with thick moisture. Wonderful! Wen" Thank you for the fast shipping. I installed the Tungsol 2C51 in my Havana DAC and it sounds excellent! I had posted a message on the headfi.org board regarding what I thought about the sound of the Havana DAC compared to my Rega Apollo - I didn't think the Havana sounded much different than the Apollo and I got slammed by a bunch of people. I listened with the stock tube and with a WE 396A and neither one sounded special to me. Well, the Tungsol definitely makes a difference in the Havana. It is much smoother than the sound of the Rega, which can occasionally sound bright on some vocals (excessive sibilance) and sounds fuller and more pleasing to my ear in my system.
