Led Zeppelen and Dire Straits Japanese SHM CD's

I have a couple of the recent SHM Humble Pie CDs, and they are awesome. My buddy who is a vinyl guy came over and listened and even he was blown away.

I received the Led Zeppelin SACD SHM Japanese limited box set yesterday. I have listened to portions of the first four discs. My initial impression is just O.K. Despite several rave reviews that i have read, I do not consider the sonics outstanding, just O.K,, certainly nothing special. I agree with a Rja, the disc quality depends on the quality of the master source. I think the Dire Straits SHM CD's sonics are much better than the Led Zeppelin SHM CD's sonics (at least Led Zeppelin 1-4).

If any version can beat the Page-remastered Zeppelin Mothership CD that came out a couple years back I'd be extremely surprised. The DVD that came with it is strictly unbelieveable.

Geoffkait,
I have not listened to the Mothership CD's. But I have read several reviews stating that the Japanese SHM CD's are the best sonics available, including the Mothership version. That is unfortunate, from what I have heard on the Led Zeppelin SHM CD's so far I am not impressed. The set is beautifully done, nice mini albums and jackets. But the sonics are nothing special. On the other hand, the Louis Armstrong Ella Fitzgerald SHM SACD is absolutely stunning.

Matjet,
There's another thread about sonic improvement with burn-in of the SACD-SHM discs. I'm not sure what I think about this reported phenomenon, I haven't experienced this with regular SHM-CDs. My feeling is that some other factors are at play here.
Perhaps you could read the thread and report on any such effects.
BTW: Most Japanese CDs have a date listed for the mastering used.
