I have not been in the market for a preamp for years and was not aware of the Saga 2. I took a look and based on your listening impressions it seems like an amazing deal with input for four sources, passive or active gain and remote control, all for $279.
Depending on his longer term plans, if interested @rvpiano can certainly follow your lead and send the Sys back within 15 days for a full credit towards the Saga 2.
For my particular listening preferences, I prefer a tube preamp and prefer two sets of RCAs out. Notwithstanding, seems like another Schiit smoking deal.
