Redbook Audio Aero Prima vs SACD palyer?

You're idea is not far-fetched. I find that my redbook performance equals my SACD performance in most cases.
You will need a DAC to get the best of both worlds if you want true premium SACD and redbook. I use an XA-777ES for SACD, and the TRUTH is that I could live without the SACD if I were playing 24 bit remastered redbook CDs via my ECD-1 DAC. There are a few exceptions, but they are very (too)few at this point.

I am sticking with my Audio Aero (Mark II) as I have a huge investment in redbook and i really don't want to clutter my sources at the great expence of my pocketbook.

I own a Mk2 Model Prima and a Xindak SCD-2 which is an SACD Player.
I have kept the Prima because it is superior to the Xindak on Redbook and sometimes so close to SACD comparing SACD Layer to Redbook layer in a hybrid CD that you have to wonder.
Thankfully I payed the paltry sum of $700 for the Xindak and for that money it is great and now I have the flexibility to purchase either Redbook or SACD.
Probably the one place where SACD shows it's mettle is with Classical recordings. Here there is beautiful naturalness that Redbook just can't match.

What an intersesting "thread". I have a new (I month old) Xindak SCD-2 player, and the rest of my equipment is Kora all tube equipment. I use the SCD-2 to play CDs, as a transport with the Kora Hermes II as the DAC, then through the Kora Eclipse preamp and Galaxy reference amp. The sound is incredible, ........... in fact better than playing SACDs with the Xindak balanced output through the Kora Eclipse preamp and Galaxy amp!!
Would you be able to advise me of any mods I can do, to really get the benefit of SACD, or know of someone who can?

If you like what you have, go buy some more CDs and forget the Mod.
