I don't know about 1.5m XLR. Anything not standard 1m can be hit or miss. Could be you find a killer deal, because nobody wants to buy the longer length some poor schlub has to sell. Or just as likely you find hardly any selection and wind up being the poor schlub who has to buy new.
Either way try and find Synergistic Research, as they have by far the greatest number of consistently good cables across the years and price ranges. So just about anything you find within your budget will probably make you real happy.
Now with speaker cables I can wholeheartedly recommend Synergistic Research Element CTS with Active Shielding. Awesome cables. $7500 new and about the best available anywhere back in the day, used ones come up and depending on length you should be able to get a pair for around $1200-1500, something like that. You will be staggered. Then for hardly any more you swap out the diodes and caps in the Active Shielding wall wart power supplies. You can do this yourself for peanuts or send them to Michael Spallone (find him here on audiogon) who has found the best sounding diodes and caps and will replace the circuit board with point to point wiring and ship them back to you fast and for a price so good I just let him do it. Because I know the difference they make and don't want the hassle of comparing diodes. The modest price he charges for the impressive improvement you get is well worth it.
So that's your reason for going CTS: sounds great, upgradeable.
