Yes the line magnetic is popular. I Hear it mentioned favourably a lot.Agreed, I previously ran them with the excellent Lyngdorf 1120 and whilst it sounded great it was just a touch too strident for me. I prefer them on the end of the Line Magnetic 518a.
I haven't got the courage for tubes, although I know people love them.
I always think it's a more specialist part of our hobby.
I have heard the Lyngdorf is a popular amplifier as well.
I am a bit old school myself. Everything I own is from the 90's. I probably come from the solid state power, blowing wind up the ass of a big pair of good old school speakers !
It was all about the mid range and powerful amplification in the 80 's, when I cut my teeth in audio.
