Music very good, quality deficient

I've certainly not the best ears ...
But in this CD you can tell unfortunately significant quality deficits.
The music itself is very good. (And that's a matter of taste, of course.)
Not everyone loves the normal piano playing without accompaniment.
Unfortunately, the recording quality is not particularly good.
One always hears a noise. Sometimes more, sometimes less.
That was something I had never ...
Unfortunately this noise overshadows the beautiful songs of Yiruma!
