I got everything set up and took the amp for a spin...it is dead quiet when nothing is playing. I listen exclusively to vinyl and the sound is fantastic. Crisp, clean highs with a clear midrange. Bass is a little lacking, but my speakers are Q Acoustic 3030i bookshelf and they don't have a ton of bass. I currently have a Fluence turntable with an Ortofon Bronze MM cartridge. However, I have a brand new VPI Prime turntable with a Hana ML MC cartridge coming tomorrow! I also plan to upgrade to some floor standing speakers very soon. I'm still undecided but leaning toward some Revel Concerta2 F36 that are on sale.
I have to say I'm very happy with my R8 at the moment and I don't plan on tearing into it anytime soon...
