This is where I am now. I'm not necessarily looking for an amp (or sound system) that is "accurrate" or has a flat frequency response, great imaging, soundstage, or any of those other characteristics that "audiophiles" speak of. For me, the most important characteristic is musicality. How do I define musicality? Musicality is defined to me as the ability to extract the most musical enjoyment from the sounds I'm hearing. For me, this probably means reproducing sound that is closest to live sound. This likely requires good accuracy and a large soundstage. "Imaging" is a characteristic that has never brought me musical enjoyment so I don't pay much attention to that. While I wasn't there when the recordings I listen to were recorded, I do know what live music sounds like and live music has always brought an extral level of emotional engagement.
This hobby/passion for me is all about the music and not the gear. I think too many "audiophiles" get caught up in the gear as the primary objective and may forget about the music. If that is how they get their enjoyment, then more power to them and I can't tell them otherwise. For me, it's important to listen to the music and not the gear. If there was a single box that could provide me with the level of musical enjoyment I want, then that's all that I would need. I haven't found that yet.
Up to this point in time, tube amplifiers have typically given me more musical enjoyement than solid-state, but that's not to say there aren't great solid-state amps out there. What sounds best to me may not sound best to everyone else. My room is different, my ears hear different, and my brain processes what my ears hear differently from others.
