No physical reason whatsoever for this to happen, so methinks its something mind related!
Has anyone ever heard of such a thing as playing an SHM SACD 5 to 6 times before getting improved sound out of it? Sounds a bit weird. Here is the link and a quote from the link just below it:
"...As a forward, and after my first listen of this SHM SACD in its entirety, the initial impression was a noticeable lackluster quality to the audio. I responded by repeatedly playing "Long Distance Voyager" (5-6 times) with the volume off. Then I listened with the volume turned back on and immediately noticed a significant improvement in the the audio as the dynamics 'opened up'. I have a large number of SHM SACDs in my collection and previously encountered this audio result with a few discs, notably The Who: Who's Next and Steve Winwood: Arc of a Diver. What is the reason for such a change? Is it related to the plastic coating applied to SHM discs? Perhaps but it would be just a guess on my part. If anything is to be learned, it is do not make quick judgements based on your first impressions of audio quality. Nevertheless, and it is important to point out, my review is based solely on the outcome of listening to "Long Distance Voyager" for any benefits in high resolution audio..... it is not about perceived issues with the quality of sound from some SHM SACD discs..."
