Dual-layer SACD Gain Issues

I've got a puzzle that developed in another thread and I think at this point it's worthy of a thread of its own. I recently purchased a dual-layer SACD of Angela Hewitt's Chopin Nocturnes (Hyperion SACDA67371/2). I enjoyed the performance but was disappointed with the sonics. I found that I was having to boost my pre-amp up to 3 o'clock to get realistic sound levels (typically most piano CD's run around 11-12 O'clock for similar volume), and the sound was a bit distant and slightly fuzzy for lack of a better descriptor. It lacked immediacy and dynamics to my ears. In the other thread there was at leas one person who had the CD-only version of the same performance and was surprised at my impressions. Unfortunately my player is not able to toggle to the CD layer for some odd reason so I brought it over to my friend's system and tried it on his player which is CD-only. The very same issues occurred with his system - preamp at 2 o'clock in his case (norm would be 11 according to him) and sound was distant and not sharply defined. So this morning I burned a copy CD (direct copy burning program that copies a cd from one drive to another) to send to Newbee (who has a copy of the CD-only version) to compare with his disc. I put the copied version of the CD into my player to confirm the burn and lo and behold not only did it play, but it had transformed the sound and seemingly solved the issues!!! I could play the burned CD at 11 o'clock and the sound was more immediate, dynamic and focused. I put the original dual-layer SACD back in the player to confirm that I wasn't off my rocker and sure enough back was the soft and distant version of the same performance. I don't have any issues with the few other dual-layer SACD's I own, so it's not a player issue, on top of which the original dual-layer had the same kinds of issues in my friend's CD-only player. So what gives!!???!!! Can anyone shed any light on what might be at play here?

What is the software that was used to copy the CD? Some of the software that claims "direct copy" really extracts the CD to audio format native to the platform. Then the volume normalization and other adjustments can be unintentionally made by the operating system either during the extraction or burning.

I used Toast Titanium 5.2.3 (pre-implementation of Jam enhancement) for Mac using the disc-to-disc copy option (Disc-at-once chosen in the preferences) with "error correction" checked. It requires two CD drives at this setting, one with the original and one with the blank. It does utilize a disc cache. I was under the impression that this would yield a verbatim copy of the disc.

I found that burned reproductions of a CD is oft times better than the original...don't know why.

I too have found that occasionally burned CD's sound subtly better than the original. "Subtly" would be the operative word here: This is not at all a subtle difference, in the case of the Hewitt dual-layer. It is quite profound to my ears, and the gain issue indicates to me that something else may be at play.

Newbee and I have been corresponding a bit on the issue, and he hazarded a guess which I doubt he'd mind if I shared here as I think it is a good one:

IMHO, actually a wild guess, when a multi-channel SACD is made, the two layer playback for Redbook playback might be nothing more than the extant SACD playback of the two front channels in the MC layer. There is obviously different recording techniques used to record multi channel performances than two channels, without regard to whether it is plain 2 channel SACD or Redbook.

Now I don't know that this is a "multi-channel" SACD, as he suggests. I'd thought it was just 2-channel for both layers. Regardless, the difference does sound to me as if the recording were miked slightly different. The SACD sounds almost like the mike(s) are back at mid-hall or back further, while the burned CD version sounds more "in-the-room" immediate...or certainly closer to a front-row seat. Not only is it more immediate, but it is better focused and dynamics are improved.

What still puzzles me, given this or a similar theory, is why the Dual-layer version exhibited the same drawbacks the SACD layer yields on my player, when played on my friend's CD-only player?
