I tried different solutions. Wave files on SSD or HDD or on SD card.
Unfortunately, every time the sound is clearly worse than the direct transfer of files from the server to the player.
The server is Naim Unitiserv, a player is Naim ND5 XS, digital cable Naim BNC-BNC.
Unfortunately, the software on both Naim devices is not very functional, there are no libraries in the range and there are no descriptions of music style or BMP. As a DJ I have to have this information at hand.
JRiver is my 3rd program after Monkey Media and (I do not remember anymore) and it is the BEST, it sounds better than the competition, the sound is less distorted. I used to send music from PC to DAC via USB but it is also loaded with distortion.
If I have the choice: JRiver functionality and perfect quality Naim I have to choose JRiver.
I wanted to try something better. Unfortunately, it is impossible to do so.
I am convinced that any sound processing program introduces distortion to a wave file by influencing the contents of that file. I tried working on dbPoweramp - fading or trimming so called. Songs always lead to spoilage of the sound and generally to a drop in dynamics. Bands begin to be nasal and the sopranos are flashy. I have a good sound KS Audio (4 pcs per 4oooW) and tube preamplifier Octave 500 and DAC is the best Hegel hd-30. This should play SUPER, while the files sent with PC and JRiver are (in truth) castrated.
As I wrote - there is unfortunately no way out because the successful event is a laid back DJ, that is time to properly choose another number to dance and 90% of my clients will not hear so little difference in the dynamics of music.
Best wishes
And it is a pity that there is no JRiver on Qnap because for me it would be a perfect solution.
