I'm using this RCA switcher by Sescom: https://www.amazon.com/Sescom-SES-AUDIO-AB-Stereo-Audio-Switch/dp/B008BMLXAU. I switch between DarkVoice 336SE and Schiit Jotunheim. I've decided to use two amps because Rock, Rap and Vocal songs tend to sound better on DarkVoice while EDM tend to sound better on Jotunheim. I'm using my Sennheiser HD600 for the DarkVoice and HD650 with 4pin XLR for Jotunheim. HD600's clear mids seems to pair better with DarkVoice, while HD650's pronounced bass seems to pair better with Jotunheim. This is how they're set up: Mac mini > Tidal/Audirvana Plus > Audioquest Forest USB A to B > Schiit Elitr > BLJ Coaxial 6ft > Schiit Modi Multibit > 3ft BJC RCA > Sescom A/B switcher > 3ft BLJ RCA to Darkvoice 336SE & 6ft BLJ RCA to Jotunheim I've also done other things to maximise audio quality: I went with 6ft Coaxial cable because of the potential reflection from cables shorter than 1.5m theoretically: https://www.computeraudiophile.com/forums/topic/16781-minimum-length-for-75937-coax-cable-revisited/ I try to make sure all of my musics on Audirvana Plus is 16-bit/44.1khz since I've heard that Schiit modi multibit only performs the 'multibit magic' on that bitrate. To get the 'multibit magic' from higher fidelity songs, I've heard that you need to upgrade to Gungnir or Yggdrasil. So far, I haven't noticed any degradation in audio quality. But I prefer to not take any risk in potentially worsening audio quality by using RCA switches. But at the same time, prior to using RCA switches, I was disconnecting and reconnecting the RCA cables to switch amps which was eventually going to wear out the RCA cable and the RCA output of the amp over time. So my question is, are RCA switches known to degrade audio quality? Do audiophiles stay away from using them?
