If you can find synergy between your source, amp, speakers you will enjoy any type of music on your system. If not it will never sound right. You can't just throw a great pick up in a great guitar body and expect it to sound great, ( buddy of mine love to mod his pick ups he about drove himself crazy) same with "revealing " 2 channel gear.I know all about swapping pickups, caps, strings, tubes, speakers... that's where I waste most of my time :) that's why I want to keep the whole audio thing simple.
I don't really have the time or patience to wait 500 hours to decide if I like something. In that case I'll never be able to audition something within 30 days and return it if I don't like it. I gave the Dentons 100 hours, and even though the highs are a little softer it just doesn't do it for me. I knew I kinda liked the LS50s within the first 50 hours. This evening I decided to hook the LS50s back into the Primaluna. While breaking in the Dentons I was also breaking in a new set of EL34, so they're both at around 100 hours now. I also swapped the two 12AU7s with some Mullards just before I got the Dentons. I can't believe how beautiful these LS50s sound! Once I got 'em dialed in the soundstage, depth, vocals, and details were so much better and the highs even got smoother. The live recordings are still a little harsh with the guitar sounding a little too bright and thin, but I can live with it for now, it's not as fatiguing. I just wish the electric guitar had more body to the tone with the LS50, and not as bright, but the clarity of an acoustic guitar is incredible! And there's this beautiful reverb going on in the room, which I really love since I always have reverb on my guitar amps.
I will compare tubes over the weekend, to confirm if that's what's helping, and give the Dentons another listen before I decide if they're going back or not.
