Purely out of curiosity, why is this? Are you a box swapper (which sounds perjorative, but truly is not; box-swapping is a legitimate and venerable sub-hobby; some people just like to try different things frequently regardless of whether they are better than what they had before)?
Did your high-end audio objectives change over time?
For example, what prompted you to replace your prior speaker with ESL, and then what prompted you to replace the ESL?
well-described!
Curiosity. Fence. Greener. Grass. I had the money so why not? I was, in the early days of hifi forums, a box-swapper, just curious about this and that component that somebody was rabbiting on about. I probably wrote as much opinionated BS as anyone else in those heady days of the mid 00s, and for a decade thereafter.
I'm not a box-swapper now. Speakers for over 10 years, my DAC upgraded several times and on the last occasion re-boxed, essentially a fully-custom component; my amp now back to the one I've owned for 10 years; TT I've owned for 10 years but I think the last major change about 3-4 years ago when it was re-plinthed and later the Ikeda arms swapped for Glanz; phono stage now an Allnic H7000V (with HA5000 head amp), my fourth LCR phono stage zooming in on what I was looking for, again owned for over 4 years, my preamp for just under that. But I wouldn't deny over the years that I've made a few wrong turns and had to rewind. Nothing wrong with that IMO. If you don't make mistakes, you aren't trying.
I'm primarily a musician, focused on early music. I play organ, harpsichord, renaissance and baroque lute. Hifi is a means to an end not an end in itself. No system anywhere can replicate what it's like to be in the middle of a baroque ensemble, playing harpsichord continuo (a small but critical part of what becomes the whole) next to a gamba player, who together play a similar role to the rhythm section in a jazz combo. But what a system CAN do is approach the musical experience of the listener, but I view this pretty much entirely now (again after many wrong turns) as about the subjective musical experience and not the objective hifi one. Does it move the internal organs in terms of rhythm? Do you get what they are trying to achieve musically? Then it's successful even if 'coloured' or even if lacking in objective 'detail'. Other people's criteria may vary, but the people's whose opinions I most respect, who I regard as peers and sometimes teachers (some are posters here), all align with this.
No system is perfect. ESLs do some things really well. DCs do other things really well, horns likewise, multi-driver speakers with He-Man power amps similarly. You choose your compromises. I'm pretty much done - not because the system can't be improved further (I'd never say that) but because my focus is on other things these days. I couldn't afford to do a music PhD after my original Bachelor's degree in music. In order to earn money, I made my career in something else, though music has always been an amateur passion. I retired last year and I'm about to start (in less than two weeks) on music study again, at a college of London University. If I have spare money now it's more likely to go on another lute.
I won't respond directly to Ked's ad hominems - unfortunately, it seems it's the only way he knows how to argue.
