Innuos Pulse versus Zenith Mk3

I currently have an Innuos Pulse with a Phoenix USB providing streaming from Qobuz into a Bricasti M1S2. The NAS I have (Synology two bay system) does not come even close to the quality of sound my ancient Marantz 8003 SACD player provides. The Qobuz songs meet of exceed the quality the quality form the Marantz.

How does the Zenith Mk3 compare to the Pulse in regards to streaming? I do not want to take a step backwards regarding the Pulse, but I would like to have access to my CD and SACD music. The Zen NG is way to expensive for me to consider at this time. Would a Bluesound Vault or Zen Mini work better? I am concerned regarding the quality of the data going through the Pulse since the NAS is of lower quality than the SACD player.

I was considering giving up on my CD collection altogether, but just this past week found over a dozen songs that are not on Qobuz that I wanted to listen to and had to resort to using the Marantz. I do not know if the songs are available on another service. I would prefer to just pay for one service (price and convenience). Some of the songs were available a few weeks ago on Qobuz are not now available. They are not available on Amazon HD either.

Any recommendations?
