While I can appreciate your passion and experience with audio, there is a point where it can be way too much. In other words, I don't envy it even a little and I mean nothing against you personally. Having to consider all of that would be living in a state of perpetual madness. I started to get that way with full range driver systems and other eccentric goals, and it ended up becoming what amounted to a constant state of neurosis that caused me to take a rather lengthy break in which to reset. I came back on the scene roughly a decade later with an old, donated Scott amp, a pair of audibly low distortion 15" monkey coffins, and my old generic CD player from around 1985. Oddly enough, and with so much less, non-pedigreed equipment efforts, the band was still "in the room," and refreshingly so. I have been careful not to overdo it since.
Take any unwashed music lover and subject them to a pair of audibly low distortion speakers in a simple stereo fashion, with life-sized SPL, and they too, will swear that the "band is in the room." It's most often the first thing that comes out of their mouth. I swore to it too at my early introductions to stereo, and I was living happily ever after until some insatiate audiophile told me I was missing out on so much more.
Now I have a simple stereo near field setup, with a pair of beefy speakers and a pair of subs. It doesn't even matter which of my amps is driving them, Including my DIY F5, the little 8 watt Amp Camp mono blocks, Adcom GFA-5500, Icepower 200ASC, Fosi Audio BT30 pro, Fosi V3, Pioneer SA-8500 etc., and my old Denon AVR.
Even my workbench can deliver a realistic image standing point blank within 3ft of the speakers. It was so good in fact, that I didn't sit for 4 hrs. Just kept feeding music through the freshly restored Pioneer. Not trying to discourage or discount your efforts, but to just bring all of this back down to earth, so that newbs that might be reading these threads, can know that it doesn't take much these days to realize what amounts to 'audible' perfection. Otherwise we get people through here stoned on information overload just throwing money at everything they think they need.
This simple setup just pounds and makes ordinary people get visible chill bumps trying it.
JBL horns?
I'm an audiophile, it's my hobby... there is never ENOUGH. (*) Well, there is... sorta... I backed off from driving a pair of stereo tube amps into two pair of english mini monitors. I figured it was a little too much...
But honestly, I don't show off my system to many people... maybe some nephews and nieces that are learning and setting up their stuff... the Raspberries seem to be making an impact! ;-) The might have been the great unwashed once, but not any more. They always knew about "good sound", they just hadn't been exposed to good "reproduced sound".
Now then, I don't think you understand where I'm coming from... I'm not one of them High Falutin' audiophiles with a six figure system... you know the type... Audio Jewelry... D'Agostinos, Wilson, Triple Signature Mk V cables... I think you and me are much alike... by your list of amps... btw, I built the Zenductors at BA23..
Dig it now? I too have a bench, read schematics, I can solder simple enough stuff... I admit that when it comes to the big amps I'll ask someone to help out.
As my wife said... " it sound like music, not a stereo system"...
My office... I sit within 3 feet of a pair of Acoustic Energy AE1s, currenty driven by a Nuforce DDA100. That's presents a near field experience where the back wall doesn't exist. These speakers sound really good too with the ACA 1.8 amps, the Mini, DIY F5 (**) even the new Zenductors I built at BA23... They are designed for near field.
My main system... well, it is complicated... lot of stuff... but it's my toy.
My nearest comparison to your home office, is my bedroom system which is currently set up with a fully restored Marantz 2235 and ADS L810s. Sometimes I'll set it up with a Sansui G7500... also fully restored.
EDIT:
But it is vintage... very good vintage, but it still lacks. It has a poor soundstage. Getting new audiophiles into the hobby with wildly overpriced vintage that will require extensive restoration is not right.
Instead, for a new audiophile, a simple system with a pair of something like active speakers and a nice DAC/preamp front end is likely the entry point. Use the smart phone ( Android I hope ) as the source/streamer... companies like Schitt and Audioengine come to mind. At some point, a dedicated android tablet ( on sale now at Costco for 200 bucks ) can be added with a USB-OTG cable so the phone is no longer involved. And a subwoofer
For about 1000 bucks, a new comer into audio can put together a very good sounding system.
(*) Did you know there is a hidden protection circuit in the Babelfish SIT amp? Mine has smoked... twice.
(**) If your preamp swings 20V, try the F4. Mine is also DIY. The DIY F5 is a little too big to sit on the desk...
Oh, I tried to post a picture... file is too large...
