SHM SACD's need to be burned in

Mceljo,Why does it have to be specifically the laser (it may be)and not heat.Perhaps there is some coating that burns off. The SHM use material that has never been used before in other disc so this is new territory. I am sure you have tweaked your system at one time or another and couldn`t explain why the sonics changed, just that they did.
That being said,I haven`t noticed any change since the burning in process(repeat for two days straight).It has only been played about 5 times since then. The only person who heard the disc when new,will be borrowing it tomorrow. I am very interested in his opinion.He may very well say `no change`
Please note to all,
I never heard this before on any other disc.
I currently own only one SHM SACD with 3 more on order.
I have a very simple and resolving system that is a excellent tool to determine how different sources, wires, or cables affect the over all sound.
I have no explaination.
I stand by what I heard.

Montejay,
I'm not doubting what you heard. I'm doubting your conclusion that SACD burn-in is responsible. IMO some other phenomenon is at work here.

Montejay - Are you talking about heat from the laser or from the player? Either way, if there is a coating that is coming off then you should be able to obtain the same difference using an oven. Also, if it's a coating then I'd say the manufacturing process should be the same on all of their SACDs and you should hear a similar difference.

The downside to trying to verify this type of thing is that you can't go back to the start. Your friend will have no chance of making a solid comparison between what he heard before and what he'll hear tomorrow. Comparing the present to a memory is nearly impossible.

Mceljo,in this particular case (SHM SACD of Aja only)there are specific sonic improvements that I have outlined that my audio friend will INSTANTLY hear.I think that a P01/G01 with the Gorb clock will offer the detail needed to confirm any change.The only question I will have for him is "does he like it now?" I stated that if he felt it was the same that wouldn't bother me in the least.I now enjoy this sacd very much.We both had a simular reaction to the sound quality when new and the lack of detail in both the high and low end of the frequency spectrum.
This is something I experienced and choose to share in this forum,and not in the least bit a scientific lab controlled experment.

Folowup as promised earlier
Brought the now burnt in SHM sacd of Aja over to my audiophile friend last night along with a SHM sacd sampler we both just purchased.
For fun,I burnt in my sampler for about 24 hours and his remained unplayed.
The first thing was that he too heard the improvement in Aja to the point that he thought it very good digital (but not reference quality). He wasn't impressed with it at all the first time he heard it as previously discussed.
The second thing was that my burnt in sampler sounded better than his fresh one. The bass was tight and the resonances were clearer. The best way to discribe the differences between the two identical sacd's were if you changed your reading glass from a 1.25 to a 1.50.
The sampler comes with a second sacd that is identical but produced using normal material.It actually sounds better than both my burnt in sacd or the non burnt in one. I haven't a clue why they would do this. The SHM is cut higher so you have to use a spl meter but this was the biggest surprise of the evening.
I do not feel the shm's are worth the price and will not be buying anymore,but they are one of the few producing new sacd's these days.
