On the snake oil and bollocks thing.
It's a long tradition of this forum that the sound of all hi-fi equipment is relative.
That equipment reviews in isolation are pretty meaningless.
That comparative reviews are much more meaningful.
So that in this thread, a Silent Angel Bonn 8 switch with one shortish AQ Forest LAN Cat 7 cable has been compared against an unconfigured Netgear GS108E with a so far unspecified LAN cable that might be Cat 5E, Cat 6 or Cat 7?
A considerable improvement in speed has been noticed with the Silent Angel.
So far we can say that a Silent Angel 8 with an AQ Cat 7 cable sounds better for over the network music than an unconfigured Netgear GS108E with an unspecified LAN cable. Nothing more nothing less.
There's no snake oil or bollocks there.
I also note that in the Pusuit Perfect System video on page 1 of this thread, that it is done as a non comparative review.
I've not spotted what the £4000 switch was being compared against.
Edi: just found the answer in the comments section of that video. He was comparing the £4000 switch with bespoke cat 7 cables against his existing cables (possibly cat 5e) into his router! Which will probably be a £30 consumer grade broadband router.
The vast majority of homes use just the router or some cheapo hub or consumer grade non-configured switch for their LAN connections.
Which is fine.
Anyway, A Silent Angel 8 with one AQ Cat 7 cable is the current reigning bake-off champion.
Let's see if it can be beaten for either outright sound quality or sound quality per pound spent by a properly configured Netgear GS108E (possibly with Cat 6 or Cat 7 cabling throughout the LAN). And if it can't, let's see of it can be beaten by a configured Cisco business gigabit switch with Cat 6 or 7 cabling. If the switch has to be in the same room as the speakers, we'd better make it a fanless one (at likely additional cost).
Configuring a Netgear GS108E looks easy enough: https://www.downloads.netgear.com/files ... _UM_EN.pdf
