Thanks a lot for your suggestions.
I will start with crossover, which brand for capacitors do you suggest?
My main amplifier is Yamaha A-S2000 but also use a homemade EL34 PP
DAC: Soekris DAM1021
Turntable: Linn Sondek LP12 with Denon DL-103
I don’t think the problem is the recordings I can understand a good one from a bad one.
I have made several tests from CD, Vinyl, Spotify.
These speakers don’t go well with bad recordings and distortion(rock-metal)!
