Best way to switch between AVR and Amp?

I have an AV receiver that I use for AV applications such as blu-ray and cable and an integrated amp that I use for music. For me, both are 2.0 presently.

I am interested in a source switching device that would preclude me from needing to pull out banana plugs and switch inputs every time I want to change the nature of my source material.

For what it’s worth, here’s the setup I use for each:

AV: (blu ray/cable etc) --> Yamaha RX-V775WA receiver
Music: FLAC via PC-->Arcam IRDAC-->Arcam FMJ a19 amp

I have KEF LS50's connected by 12 gauge wire that I connect these two setups to.

I have seen some switches that may work:

1) Niles DPS-1
2) Beresford TC 7220
3) OSD Audio ATM-7

I’d appreciate any input as to:
a) The possible sonic degradation that I would experience by the use of one of these switches
b) Whether one of these switches is better than the others for my purposes. (I am partial to the OSD because it supports IR and using a remote would be handy)

Thank you!!
