Personally no. Been there. I got to over 10k worth of amp and floorstanders. Once I got over the novelty, in truth it was no more enjoyable than my mid 90s NAD and B&W budget setup. Yes it was more detailed, refined, dynamic, balanced but more pleasure to my life a year later? No, so I sold the lot, invested in sonos (surprisingly good as a 2.1 setup with play 5) but I sold that too. It took up too much space, and I hardly had the time to do the critical listening nonsense. My used / budget system I've just setup works fine in that I can hear all of the elements that make music fun, for me it's usually more about the situation, the company than the nth degree of detail these days. Oh and I use QED79 cheapo cable, and plug my units straight into the wall! I guess I realised that hifi itself became the hobby, not the music and that wasn't healthy in the long term.
I can relate to this in so many ways ... one problem though is if you have a setup you don't like whilst you want to put it out of your mind and ignore it, if it's "harsh" or severely lacking in terms of other things you've heard it'll always just annoy you .... more than it should and that in itself will detract from the music / enjoyment.
I have in my work room / desktop setup an SMSL AO200 with some old Wharfedale 9.1's and in that room love it.
In a reasonable size kitchen living room, a Denon M39, I wanted "better" speakers than MA BX1's so tried B&W 607's and didn't like them at all .... ended up with Elac B5.2's and the combo's amasing and a much "fuller" sound than the BX1's.
The speaker upgrade in the Kitchen / Living area made me realise how muddy the speakers connected to the AVR in the lounge were, tried upgrading them and hit the "harsh" I mentioned above.
I upgraded to a dedicated amp rather than relying on the AVR hoping that'd make a difference and it didn't so changed the speakers but they're no different and whilst great with some music can just grate with other tracks so now looking at spending £3/4k on a set of speakers.
Problem is, you end up chasing the dragon, I'm sure you can get great setups that work like in my Kitchen / Living and work room that wouldn't work in others, but when you've heard good in one room, you want to replicate that in the others ... especially if you have a multiroom setup and go from one to the other.
I'm sure there's that "Mecca" combination out there that's probably less than £1500 for a great setup but unless you come across that from the get go it's easy to think .... maybe I haven't spent enough.
Other end of the spektrum, I bought an £80/90 panasonic mini system that included speakers because the unit had some funtionality I wanted. The unit was "OK" but you couldn't bear to play it through the included speakers.
A few weeks back we were sitting outsde for a drink, their outdoor speakers were so appallingly bad, even the other half said they're better off switching them off.
I think it's quite hard to step back from a £10k combo if it was good unless you found something you really liked for less.
In my opinion, it's about finding that balance and if you could demo every amp / speaker out there, I'm sure there are some £2k systems (maybe 2nd hand included) that the difference up to £10 or £20k if you had it just isn't worth it.
