My low tone hearing is pretty much shot after 20 years of flying Aerobatics (mainly in Pitts Specials) so the really good stuff is pretty much lost on me these days.
I do have a few home Audio systems in various rooms though - Cambridge Audio amps, Monitor Audio Gold series spekers and 14 Sonos speakers of various types. These days I only stream stuff (note to self - must sort all my old vynil out !)
The main effort goes into Valve Amps & pedals for my (20) Guitars - Sort of "DIY" your own racket I suppose, but I do enjoy playing ...... and fiddling with all the different combinations of Pickups, Pedals, Effects and Amps is endlessly fascinating.
The digital stuff can be made to model virtually anything ...... but it never sounds as good as the Valve Amps. The problem is that the valve stuff has to be driven a bit to get the tones out (and then they are LOUD !). I have to stop when the dog starts barking ;-D
