Just received a 3m and a 1m Ethernet cable from Blue Jeans cat 6.
£60 for both delivered to the UK.
They replaced a free old cat 5e and a very cheap Ugreen solid core cable.
They do sound noticeably cleaner and clearer, but without being sterile.
So a worthwhile upgrade for 0.5% of the value of the system.
One odd thing is that the audible volume of the system has changed significantly. It is now quite a bit louder at a given volume number on the dial.
So the top volume that is now comfortable playing Tidal is about 38, whereas with the old free/cheap cables it was more like 45.
Does this make any sense and why is it louder?
