1. The room and your speaker placement are vastly more important (as
above.)
2. Any argument that involves "noise" is by definition incorrect because
the TCP part of TCP/IP makes sure the "haul" over the network is
flawless and the NIC hardware/firmware does the same for the data to
hardware interface <in both the sending and receiving network "card.">

Anyone who claims TCP/IP does not deliver bit perfect just does not
understand the way it works.
