Here's a fire starter: Analog is as good as SACD

Restatement of a post above:
It all depends on the recording and mastering done by the sound engineers.

 Sometimes vinyl's preferable despite the snap, crackle & pop because the compression effs up the CD so much.

Sometimes the CD, SACD or HiRes online track is well recorded -- if so, it will not have the snap, crackle, and pop of vinyl, not will it wear out when you play it a lot.

I would suggest upgrading the speaker cables, followed by a better arm. If you can't hear a difference then, your speaker may no be as highly resolving as you want/need.
My 2 cents.
Best,
Mike

@randy-11,
I agree, except I have few if any CDs that sound as good as their LP counterparts. I do have a few SACDs remastered from the same tapes as their well made LPs. I suppose the comparison is not totally a controlled experiment. Remastering may have changed the sound significantly. What I am saying is that I am unable to hear differences that really matter when I'm listening for enjoyment.

@mrvordo 
I'm working on the cables now. 
Does anyone have any experience with Zu vs. Canare 4S11? I can actually get some Canares for about $75. The Zu Libtecs about $140 and Zu missions about $90, all bi-wire. 

Understand. In that case, after the speaker wire upgrade (which should be the number one thing so that you can hear the differences better), a better arm, phono, and or pre will make a difference. If you are satisfied with the sound from SACD, the the phono may be the unit to make the improvement you are looking for.

Good listening,
Mike

Thanks. I am satisfied with both, except for the impulse for more, more, more that we addicts feel. Is there anyone out there who has both LP and SACD playback in their systems who feels that one is a lot better sounding than the other? The answer to that, I suppose, would lead me to a reasonable conclusion as to what can be expected.

I really appreciate all the help.
