Enjoying LEEDH Processing….

Timely discussion, I just noticed the Leedh option in the app recently (don't use the Lumin app much as I am a Roon user) so got curious and just today removed my beloved McIntosh C2500 tube preamp from the chain and much to my surprise a noticeable improvement in all aspects. I have yet to detect a sonic downside to going straight from the Lumin S1 to my MC452 amp. I will be switching things back to confirm my initial impressions, but it is pretty obvious to me and frankly I didn't want it to sound better. I only stream so the preamps only function was to process the sound (for the better I hoped) and volume control. I will need the lumin remote if I stick with this because using the ipad for volume control sucks for me. Obviously, everyone's associated equipment will vary the end results, however I think the Lumin and I guess the leedh volume processing is an important part of the equation. I have never tried a dac/streamer without a preamp prior to today.

This is what makes our hobby fun, experimenting with our gear and seeing if we like sonic changes. I never would have thought removing the preamp would have changed the sound to my liking but it sure did

The LEEDH processing theory is really interesting; in that what is the cause of the sound improvement?

To vastly simplify, for each step of the digital volume control LEEDH uses a whole number. i.e instead of 3.14141414141414 into infinity they use 3.141

So does using exact numbers mean greater accuracy and thus better sound? Or is it the whole number has far less math overhead, so the substrate of the chip itself is not working as hard, leading to lower noise and thus better sound?

The math theory is very interesting.
Either way finally we can have digital volume control that sound decent, because it never could compare to an analog volume.
