I've gone a different route. I really treasure vintage stuff, especially speakers and have restored several including ARs, Advents, JBLs and Empires to name a few, but now I've finished building an amplifier and a passive preamplifier. I've also built my own VU meters and my own DIY interconnects in which I make the cable (no, I do not draw copper wire), and am now considering a full function, remote controlled digital preamplifier.
I'm also going down the music rabbit hole, picking up most of the Beatles set, Jimi Hendrix and ELO, all on vinyl of course. Some Van Morrison, a bunch of "greatest" hits by various artists finished out the virus era.
I have learned one thing, and that its not necessary what pieces of equipment you have, its what you have it paired with and how its connected together and powered. Having 5 systems in my vinyl room, I can do a little swapping and it always keeps things interesting. One of my great joys is listening to my 3 channel stereo system based around the vintage Marantz 3300 preamp. It features a center speaker (in mono) on the front wall and left and right channel speakers on the side walls. I usually listen to "Pipe Dreams" on Sunday morning. The Empire Grenadier 6000 speakers can make my floor rumble, and the JBL Studio 520c center channel fills in the space. Its almost like the real thing.
I've also learned to accept these vintage pieces of gear for what they are, not what they should or could have been. Many have great strengths. No piece is perfect, none will ever be. Accept them for what they are and you will be happy. Enjoy the music.
