Your original comment was that Roon and Tidal trounces MPD on every sonic aspect. I tried to determine if your were importing your files from CD or if you are using downloads. I tried to find out if you were importing your CDs if you were using aiff, wav or flac or other means. You seem to be saying that you imported your music using one codec and make batch files using XLD which may be the problem. Your answers have not been explicit enough for me to determine why you say Roon MPD which no one concurs. But, regardless enjoy your Roon. You don't have to explain any further.
Either I have been very unclear, or you simply do not understand how any of this works.
Whether I rip a CD or get a digital download, it does not matter as long as the information in the file is the same, meaning they are the same master on the CD and the download file. It's all 0 and 1 and easily verifiable.
Whenever I download from a store or rip a CD, the format is always FLAC (lossless but compressed).
You should know that both WAV and FLAC are lossless and identical in data. FLAC is compressed, whereas WAV is not (uncompressed). I only made a duplicate library with WAV for MPD use, so the BDP-1 itself won't have to do decompression like it would with FLAC.
With Roon, the subject of compression does not matter because Roon uncompresses all lossless formats to the same PCM before sending it to BDP-1. So whether you use WAV or FLAC in Roon, once the information gets to the BDP-1, it sees the same thing (PCM).
Do you know what batch conversion and transcoding is....? All I'm doing is making a duplicate from FLAC to WAV on a separate hard drive. The data is still the same. It's just uncompressed so the BDP-1 won't have to work harder. I'm not combining multiple tracks to one track. What I mean by "batch conversion" is that I can convert multiple folders of FLAC to WAV automatically.
In this whole process, data is never changed or corrupted. It's still the same data as it was in the studio master. Compression or decompression has nothing to do with that.
