It is physically contacted meta to metal with solder, I could have bent around but trying other caps means I am not committed and it sounded fine. If the LPs is shielded from the other components why is a copper wire any different to a board track ?
Was it a DIY amp I would use this method since I still have enough old Cerafine caps but it is a commercial amp of considerable value and I need to roughly follow OEM choices to preserve that value .
It is a modded Blu-ray player. I do get the point about value preservation and alterations in some cases being frowned upon but you can do some much neater work or give yourself the ability to revert back when you sell. Ive had about 20 caps in and out of some PCB boards and if you are careful clean before and after desoldering they all looked like factory fitment.
I actually quite like small flyleads in some situations which allow you to experiment before final fitting. In the BR player situation space and options meant that I was unable to fit the caps I wanted to the board in any case - too large.
I also get the point about location but 90% of the time, the only meaningful impact as far as I can tell is high frequency components and impedance at high frequencies from the ESL, which matters some of the time but given I have altered because of this potential impact and had zero sonic gain in doing so, I'm more try it and see and not over theorise.

I do critically listen, my only interest is improving the sonic performance, I do measure the output end to end and am happy to make progress for my own purposes. I'm only sharing my experiences. Criticism as always is easy
It's a tube amp and those were in big part assembled point to point with long leads. I have no problem with the concept and already thought about it.
Its not a secure joint, solder is sensitive to stress and vibration, and there is no strain relief and plenty of scope for a lot of torque given the lever-arm of the wire and small area of contact. It is a failure waiting to happen, fine for experiments, not really for long term use. A proper lap-joint with shrink-wrap over it would be preferred as the contact area is greater and shrink wrap provides strain relief (and insulation of course).
In this situation the wire was bent and rested under it's own unassisted before solder, with some tension from the wire to attach it (it helps me to solder and know it is attached) The player sits on a shelf and isnt going anywhere or vibrated. I do shrink wrap most solders when complete. This now has a MiCA cap with legs folded around anyway.
No sloppy laymen's work is easy.
The modus operandi:
1. A wish to replace stuff in good quality equipment without necessity
2. deliberately buy the wrongly sized caps based on absolute nonsense reasons
3. don't mount the new caps mechanically to the PCB or chassis but let 'em hanging loose
4. use excess DC pulses carrying wiring/antennas with denial of well known electrical facts
5. Make wrong connections to the caps without ring that enclose the caps contacts that are both mechanically and electrically sound.
6. convince yourself that stuff has become better with cherry picked details that suit and deny criticism.
7. Defend choices based on perceived sonical improvement.
This MUST be tube pilots work as one rarely sees this elsewhere. Chances are likely that comparing the modified PSU with an unmodified one is in favor of the latter.

There is always the Audio Note Seiryu series, same as the kaisei but different lead outs, a fair bit cheaper.
1. A wish to replace stuff in good quality equipment without necessity - A desire to get the best components where others have chosen to compromise I am prepared to experiment
2. deliberately buy the wrongly sized caps based on absolute nonsense reasons - Or you restrict your choice on PCB design and component size
3. don't mount the new caps mechanically to the PCB or chassis but let 'em hanging loose Ive never had caps hanging loose !
4. use excess DC pulses carrying wiring/antennas with denial of well known electrical facts Many power supplies are remote and carry DC to the circuit (and yes I know they often manage impedance issues from remote location). Most DC supplies track the supply across with thin flex, no screening and no concern for other board components in factory components anyway
5. Make wrong connections to the caps without ring that enclose the caps contacts that are both mechanically and electrically sound. A board amounted ring was only a thing from PCB design, many hard wired components with tabs and other mounts as we know
6. convince yourself that stuff has become better with cherry picked details that suit and deny criticism. As I said before I A-B everything and do go back, I have standard BR players, pre amps etc - I have two of them so this is not the case with me on many occasions I have gone made many changes before going forward
7. Defend choices based on perceived sonical improvement. That's how you make your decisions isnt it. If you A-B, often double blind that's fine by me that's what I care about. There is NO definitive measure SNR, THD, SINAD etc are useful but don't correlate enough
Anyway I'm distracting from the OP, so apologies
