@Dave-L : Thank you, but I see no reason. I have fun to test different stuff, but there wasn't that many interesting stuff included IMHO.
If I look back there are only a few I would consider again (both, speakers and amps).
Maybe it is interesting for some people here to name the ones which I still like.
Speakers:
Dynaudio Confidence C1 (maybe, long time ago that I listened them)
Odeon Midas SE (if I'd have a smaller room) and
No. 28 SE (current)
Harbeth Super HL5+ 40th. Anniversary Edition, Compact 7, Super HL5 (lineup = ranking)
Klipsch Cornwall III (as a second speaker)
Pro Ac Response D 38 (maybe, long time ago that I listened them)
Sonus Faber Guarneri Memento (still love them)
AMPs:
Acoustic Masterpiece AM201H (current, incredible sounding amplifier)
Audiomat Solfege Reference (terrific amp)
Berendsen IPA 80 (great budget solid state amp)
Croft Charisma X with Twinstar IV H.P. (if I have the money over I'd have kept them as backup, one of the greatest combos I have ever listened to)
Naim Nait XS and XS-2 with Flatcap X (still like them)
Rega Brio-R (with the right speakers on of the most fun amps I have owned, can listen to it for hours and hours)
Primare A30.1 (current, great allrounder amplifier sadly it doesn't match with the Odeon No 28 S.E., so I'm selling it right now)
