"@audiotroy I only used the Marantz in conjunction with the PS Audio DAC since it needed a preamp to be most effective. The NAD runs straight into my amp. Power conditioning is from a PS Audio Quintessence and the power cord is a Pangea AC14XL Mk II that I recently picked up to test out. The power conditioner is plugged into the wall in a PS Audio Power Port outlet."
@audiotroy You obviously have a high regard for PS Audio. I am well aware of the quality of their DAC Sr. Why did you think you needed and what made you choose their Power conditioner and Audio Power Port? What were results that you heard after purchasing? I also have a Marantz Pre.
Thanks
