My first recommendation is upgrade the tube of your Freya plus with pavane tennis ball 6sn7 on the tube buffer. And pavane 6sn7 uk version tubes on gain. It will transform your Freya closer to a highend preamp, for $250 cost, I love my Freya plus ,For Dac Tmr audio has Ares Dac and Schiit gungnir listed..check it out.
