Tubes! I love em! But I also dont Jam out like I used too. If all I listened to was mainly hard rock and classic rock and I wanted to listen really loud then all SS gear is probably going to give me what im looking for. But now that im a bit older I find myself listening to more Jazz and Blues. I have gone through several SS and tubed pre amps over the years, one thing remains constant for me though is my speakers (Dynaudio Contour 3.0) and amplifier (McIntosh MC352). Tubes inject tonal beauty with sustain and decay like no SS pre amp can, with that said, Tubes tend to not slam or hit as hard as solid state. THERE it is!
