Sean, I know you are into rock music pretty heavily, but if you have any jazz leanings, I have found that the Charles Mingus "Mingus Ah Um" SACD to be a disc that I really like.
Upright bass is quite realistic; the notes have the correct attack, crescendo, and decay of the instrument, with a believable air around them. Horns have nice bite. The sound of Mingus(him, in particular) on this SACD offers something that I was previously unable to hear through my system through CD.
*** Disclaimer for all the anti SACD fanatics, I HAVE NOT TRIED A $3000+ CD PLAYER IN MY SYSTEM ***
I am not sure if others agree with me being impressed with this disc, but if anyone out there has it, I would appreciate them also chiming in.
This disc might represent something that fans of classical, rock, and jazz might be able to use as a common reference point. It features various instruments, both visceral and delicate, and I find it well recorded despite its age. On the down side, there are no vocals, which I find important and may preclude it from being the Audiogoner reference.
While introducing the Rolling Stones 1960's catalog is big news, I am looking forward to being able to buy whatever I want on SACD. I am more into Led Zep, The Who, The Yardbirds, and a ton of more modern stuff. That's when they'll get my money.
The thing I notice most about SACD is getting the weight of the recording much more correct than CD through just about any CD player I have come across(the elite excepted). That and the "realness" are what sets vinyl most apart from CD to me. And, while I still think that at this point vinyl trumps SACD, SACD represents a definite step closer to what I seek. I think that from the lower midrange on down, SACD makes me happier than CD with its weight and believability. There is also a clarity that SACD recordings seem to possess. I don't have enough experience yet with SACD, but I am holding out hope about the realness.
With each new wave of players, Sony targets the masses. I think that for audiophiles, the best has probably come to us from Sony. I know that my 28 lb 333ES player sounds better to me than any of the 7 lb plastic faceplate stuff that has come since. If SACD will become the future of the high end, companies like Musical Fidelity, Linn, Audio Aero, YBA and the like will need to take us there. Just like it was for CD...
My complaint about SACD is the lack of software, although it seems to be on the upswing. The thing that I don't like about the SACD campaign is the way Sony wages it. They have no idea as to how to market the software. And, Sony does not have the either the intestinal fortitude or brains to fight a format war. Does Sony realize that the real format war may not be with DVD - A, but with CD? Maybe I am crazy, but I think that Sony should stop pressing CDs, and just sell SACD. With the amount of material they control, people will be forced to then buy the hardware, and it will all feed off of itself - others will press SACDs or hybrids. Believe me, people have no adversion to buying hardware(witness DVD, MP3, cell phones, palms, satellite tv and now radio), but you have to make them buy into the software.
