A fellow Audiogon member was kind enough to offer to make RealityCheckCDs from a few of my redbook CDs. Last night, I listened to a RealityCheckCD copy of a friend's commercially produced progressive rock CD which is a nicely layered and sonically dense recording, although I've always considered it edgy and bright. The RealityCheckCD mitigated the digital edge and lent some naturalness to the music, however it also somehow affected the ambience and extension.
From a burned compilation CD I own of audiophile quality recordings, I compared Thomas Dolby's "I Scare Myself" to the RealityCheckCD version. The RealityCheckCD version defines the instruments and voice a bit more than the original burned CD, and the leading edge of the piano attack is softened a bit. I can see where this would be pleasing to some listeners. Overall, however, I find the RealityCheckCD, at least on this track, collapses the soundstage height and width and diminishes the layering somewhat. There is less ambience in the music, and micro details are reduced. For example, in the first 30 seconds of the track there is some brush work on a ride cymbal that is clearly defined on the standard burned CD. The RealityCheckCD version either pushes this cymbal work back in the mix or muddies it, I'm not sure which, but I suspect some tweaking in the frequency range where the attack of this sound originates, and I think this goes hand-in-hand with the loss of ambience in the recording. There is certainly a difference in the two recordings, but I'm not sure the effects of the RealityCheckCD process would be beneficial in all cases. I prefer the original version of this track, and it's a song I've been using for quite some time to evaluate equipment.
I noticed this also while listening to "Walking on the Moon" by the Yuri Honing Trio from the same compilation CD. The saxophone sounds more natural in the RealityCheckCD version, and much closer to what I remember my vinyl sounding many years ago. However, the music sounds like it's being performed in a closed, cloth-walled room without any circulating air.
So, the RealityCheckCD can make the music less digital and more natural, but to my ears, it also tweaks with a recording's extension and ambience to a degree that I find unsettling.
