I only use Franks Silver Reference RCA and XLR and Silver Resolution PC and Magic Power Digital Reference in our system upstairs. Also Silver Resolution speaker cables and REL Speakon cables by Signal. Frank builds a high quality product at very fair prices and you know what you are getting.
My upstairs system is Simaudio 600i, 680D DAC and Innuos Zenith, QLN Prestige speakers. All purchased used. Sounds great but I really am a tube guy.
