An easy question for me, because only omnis interest me and I now have my end-game speakers in the shape of Duevel Venuses. I am slightly curious about German Physiks; less so about MBLs because I could neither accommodate nor afford them (and find them hideously ugly anyway).
I do fancy a mono system with a Voigt Corner Horn and a WE205D valve amp... but I don't have an available corner (radiator, chimney, bay window, door...), so that remains just a fantasy!
