It takes one to know one;
@Pearljam5000 my friend, as an bonafide aficionado on the subject, this is accurate. My one and only regret in this hobby is occasionally falling into the 'listening to gear rather than music' trap because I suffer the same condition, don't let it happen to you!
Your 2 options are get over it, which is of course easier said than done, or accept it and find some way to make it work for you. Here's some totally unsolicited advice from a stranger on the internet who can empathize with your situation. The strategies I use, maybe they're useful maybe worthless:
Never pay full price for any depreciating asset - b-stock (open box/customer return, refurb,
blemished) or closeout pricing only. That way I can sell for minimal loss if it
doesn't work out. In a way, this eliminates 90% of my "options" because I don't see full price as an option.
Get the cheapest option of something that interests you, and think critically "Do I want more of <this>?" For example, for my friends who aren't in this hobby I explain the difference between JBL/Revel and Kef/Genelec as 'wide' vs 'deep'. Almost anyone reading this knows that's a dramatic oversimplification, but to decide which I preferred (spoiler: both) I got a set of LSR 305's (used) and Kali IN-8v1 (open box) and lived with them for some time before stepping up price-wise.
Don't be afraid of return periods. I always get someone on the phone, confirm my expectations, if I move ahead I have the invoice emailed to me and then reply confirming the return policy. An aggressive sales rep might give you hassle, at which point I usually just defer to the email so I don't have to listen to their insipid whining when I could be listening to Chubby and the Gang.
Last, and I have no idea what options exist for this outside the USA, 0% loans if you're pretty confident but not totally confident about a selection. Do not get suckered into a higher overall price just to land 0%! Just as important, don't do it if you aren't able to pay it off by the day such offer expires because the millisecond that rolls over, your selection just became x% (23% is what I tend to see) more than it would have been outright. In the USA, such deals can be anywhere from 6-24 months; you'll know within 3 months if it's the right choice, leaving you with at least 3 months to sell.
With that little list of rules, I've maybe lost 5-10% at most, while gaining a lot more confidence in my perceived vs. actual preferences around gear. Even then, 1/3 of that was on shipping/donations for amir and Erin to test a few submissions. Anyways, the KH420 sure is great... My take vs. 8361: here in USA it looks like KH420 price just went up to $5200/ea, so unfortunately I'd have to lean toward the 8361 simply because, for the moment, it's a more future proof option. Will be interesting to see what GLM 4.2 brings. I believe in other parts of the world, KH420 is quite a bit cheaper especially if VAT doesn't apply to you so decision wouldn't be as easy. Apologies for polluting the thread with these pontifications
