HI thanks for the replies, guys.
Look, I'm not personally trying to assert that there is a difference between CD's burned by a DVD-R vs CD-R drive. I was simply wondering if anyone else had noticed or tried to quantify what my father says as an anecdote. Since you don't know him, and validation of his engineering skills isn't really something I'm after, I'll just ask you to understand that he definitely knows what he's talking about.
He's one of the top 2 or 3 piano tuners alive, as an example of the type of ear this man possesses. Travels around Europe tuning pianos for concert musicians, is a master recording engineer and an accomplished classical composer in his own right. Having sat down with him when he showed me two different CDs, one recorded with a typically tuned piano (the term is escaping me... is it 440?) vs his method of tuning, thinking "oh yea, I"m going to pretend like I hear a difference and make him feel validated." Boy was I mistaken. The 2nd CD had every note resounding clearly through his stereo system, no individual notes interfered with others, and rang out clearly longer than the 1st CD. After hearing that his ear, if you follow what he's pointing out to you, DOES spot minute, and sometimes magnificant changes to purity of sound, I tend to think he's on to something here...
But... maybe it's the quality of the particular drive itself, and they simply aren't made as well anymore ? (CD-R, DVD-R, all of it)
I posed the question to him again, and he let me know that, not only is the above comparison between DVD-R and CD-R consistent for him, that there's one particular SONY drive (I'll try to find out the model) that is what he believes to be the best sounding CDs. It is an IDE connector model. He swears that not only is there a difference between the CD and the multi-burner, that the IDE connected ones sound better than SATA.
So, his solution? Buy like 20 of those SONY drives and never have to run out again in his life. Though, as I'm finding out now, IDE enabled motherboards are getting less and less common. He'll eventually run into an impasse, I think.
