Before my last attempt at this post was derailed by a ROCK hardware problem, I was trying to figure out the best Roon endpoint for my living room.
The ROCK (specs below) is co-located in the TV room with the internet connected router, NEST WiFi router, Denon - AVR-X3700H 8K Ultra HD and surround speaker setup, etc. and is connected via HDMI to the Denon receiver.
Right below in the living room is the Krell KSA-300S and KRC-3 with another NEST WiFi router with an AirPlay enabled Airport Express connected via RCA to the preamp. There are a pair of unused balanced XLR inputs on the KRC-3 that would be ideal for a Roon endpoint.
There are a pair of Sonos speakers in the kitchen, a single in the bedroom and in the office along with more NEST mesh nodes. I can live with the sound from the Sonos speakers, but I’d like to get the best bang for my buck on an appropriate Roon endpoint for the Krell.
The Hifiberry XLR is pretty mediocre judging by ASRs review and offers nothing over its RCA version. I would hardly call that bang for buck it’s just cheap as chips and for a very good reason. Why stick a very very mediocre device into a decent pre and power combo.
Hifiberry are cheap and cheerful they are not high quality and never have been. I have a few of their products, but only their amp2 now in some home made wireless speakers. They sound ok but good not really. I imagine the new one will score the same as the single ended version.
