That's a harder question to answer since I don't use a D1600
. I can only relate to burning on my pc's burner. The rule of thumb when burning is to burn at the slowest possible speed when you are burning audio. The rationale is that you minimize burning errors that could degrade audio quality. I know its all 1's and 0's but there was a study conducted where high burning speeds caused higher error rates for audio cd's as compared to data cd's. The error correction algorithm for most cd readers could easily compensate for data errors, but for audio, the algorithm supposedly had a detrimental effect on audio quality.
If the D1600
allows you to burn at slower speeds, try that. As for music losing quality, I wouldn't be able to know what the qualitative differences are until I hear it. If the D1600
is still under warranty, it wouldn't hurt to have it checked, I suppose.
