Redbook Audio Aero Prima vs SACD palyer?

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.

I've had the same experience CD vs SACD. My Wadia 861 sounded much better playing redbook CDs compared to a Sony SCD-777ES playing SACDs. Same music/album, of course. This was in my friend's system using his cables (TARA, V-D), his pre (Spectral) & his power amp (Plinius SA-250).
My experience was brief (few hrs one evening). Many people write that one has to live w/ SACDs for a long time to perceive just how good they are over CDs.
That's bollocks! In my experience, if something is much better sounding, I can tell immediately. It takes me about 1 track on a known CD (music known to me) to figure out whether the sound is better or worse (to whatever I'm comparing it to - electronics to electronics or CD to CD). If one has to live w/ SACDs for a while before perceiving their superiority over CDs then I don't consider that any sort of superiority! It's a slight difference/improvement that I cannot justify as a major expense in my system.
Over on a EMM Labs thread, I read a whole bunch of owners just brown-nosing each other informing all those who read that thread just how good the EMM Labs modified Philips transport is for SACD!! Looks like people justifying their huge investment into SACD (if they didn't justify their postion, they'd look foolish spending this much money!). Most of world has seen marginal (consumer ROI) improvement in SACD. Many people in the audio biz have also written about SACD's marginal improvement over CDs.

My intention is *not* to touch off a battle over this subject (it's been flogged already in another thread on Audiogon) but to suggest that the investment in SACD is probably not worth your hard-earned money. Atleast not right now.
If you insist on getting a SACD player, get something inexpensive so that it doesn't pinch you should it not pan out for you for one reason or the other.
FWIW. YMMV. IMHO.

I've had the Wadia 861, the DCS stack(w/o dsd) Sony SCD777ES, Marantz SA-1, PassD-1 with a CECTL1-X transport and I have to say that anyone who doesn't hear the difference between a high-end sacd player and high end cd is just missing something. I just bought a Krell SACD Standard and I'm here to tell you that for 2800 used the cd is equal to the stock Wadia (although you need a pre-amp) and the SACD is equal to the Marantz SA-1. Even the DCS Delius and Purcell with a CEC transport on cd can't touch SACD. I don't mean pcm -sacd conversions(which still sound great), but true dsd recordings can't be beat by anything except vinyl. Really expensive vinyl. Why the hatred for sacd? It's our only hope for a large hi-fi play list. My suggestion would be to buy a sony scd777ES $1300 used(great transport); run the digital out to your dac of choice (1000-2000) and run the sony sacd into your pre-amp. Get both for not much$
