BTW There are no 59K or 29K or 15K or or or.. I don't pay nutso money for gear when 50% of the sound is the room alone. ALL Speakers 25%, gear 20% and cables 5-15% depends on DIY and what you actually pay for cabling.
A lot of amps can do the job for me from 400.00 to about 3K. Nothing fancy.
Preamp? That's different, I spend a few quid..
I have ZERO issues with others paying 59k for cables.. 100% their business and absolutely none of mine.. I'm glad they are happy. So am I. :-)
