Although I am aware of Darko’s involvement with the ‘other’ technology that Mr Bates is referring to above. So I remain a little cautious. Taking the article at face value though, it does look promising.
Just curious how many people are using digital volume control. I have two setups, my office rig is sitting right next to me so I just reach over and turn the knob. My music room amp has a remote. So, with the exception of a couple of Sonos speakers, I never use digital volume control. Considering the sound quality of the Sonos, the volume control has no effect.
Assuming Roon DSP engine and volume leveling are turned off: with Lumin running RAAT, Roon Core tells the Lumin endpoint the volume value to use via RAAT. Lumin then applies its own digital volume. In this scenario Roon 64-bit volume is not applied.
I do not have a lumin and I use an RME ADI-2 DAC which has a volume management by remote control (DSP inboard) but not manageable by Roon.
On the other hand, I use the Roon autolevel to avoid differences in levels (> 18LUFS, especially with Roon radio)
I asked the question because if Leedh processing was superior in quality to Roon 64b float, it could replace it.
2 things: if the superiority is demonstrated and if Roon … agrees to pay the license.
Referring to the title “Perfect Digital Volume Control?” I would have to reply with a resounding “YES!”
As it is these days - I had quite some time available for tinkering with my system and so I activated Leedh on my Lumin D2 (with LPS) and took the pre-amp (Pass XP-10) out of the chain.
I did not really expect much from the change (especially after a few hickups in the beginning, which were entirely my own fault), but what can I say …?
I was totally blown away by the difference in sound!
What followed may be a bit exaggerated, but I actually bought an X1 and put aside the D2 and XP-10 for sale. My system now sounds better than I would have ever thought possible and I am absolutely stunned by the difference!
And no: I am in no way affiliated with Lumin.
