I am thinking about getting the NFB-10ES3 but I am confused about the difference between this and the the NFB-28. The only noticeable difference I noticed is the NFB-28 replaces outputs for analog inputs. Is this it, or am I missing something? Additionally, is the TCXO upgrade worth the extra $40 (on either option)?
the nfb 28 is also more powerful I think, and others have said it's a little "cleaner power" due to the extra Core Blocks in side of it
