Spectral Audio users need your input


I would appreciate any input from Spectral Audio users on what type of digital front end they use. I sold my digital gear Theta Jade with Progeny DAC a few years back and I have been listening to Lps mostly. I am now looking for a used digital front end (1K to 1.5K) and I am curious what works well with the Spectral.
I have a DMC12 pre amp and DMA100 amp with Martin Logan ReQuest speakers

Thank you

in the $1,500 price range - check out the new cambridge audio 840. see robert harley's incredible review in absolute sound.
Thank you for your suggestions. I am considering the CA 840, Arcam 33, 36 and the Audio Aero Prima III
Perhaps consider a Sony XA9000es ~$1500. Detailed dynamic sound will support the Spectral clarity. The model just below it sounded very good with my Spectral but the XA is a solid improvement imho and build quality is very good. You will want good isolation from the digital to enjoy the full benefits.
