Icorem, you posted that "[w]hen hooked to the RCA input the ref5 sounded very good but as I said the volume level was at 50 and up so I won't go for the ref5 as these limitations might cause problems in the future." With respect, your post is a bit of a non sequitur. The volume control level setting is not a limitation per se that will a fortiari cause problems in the future.
That said, if you find a linestage/pre that sounds better when hooked up to your AudioNet MAX, ... definitely go for it. In audio, there is no such thing as one size fits all.
