Believe it or not, we actually try really hard to keep marketing BS out of the LUMIN material, but it's not always easy lol.

It's not easy to describe Leedh Processing in layman's terms, but I'll try my best:

Let's assume we have these values for a volume level:

-12.0db, 64591

-12.1db, 64468

-12.2db, 64300

-12.3db, 64189

-12.4db, 64045

-12.5db, 63886

-12.6db, 63700

Let's also assume that I want to reduce the volume slightly - say from -12db to -12.5db

Traditional volume control algorithms (including our previous one) aim for volume adjustment accuracy, so it will just take -12db and -12.5db (for 0.5db adjustment). But Leedh processing aims for exact numbers, so in this case we will use -12.2db and -12.6db instead (note the zeros on the end). This means the adjustment is not exactly 0.5db each step, but the values are more "exact".

The rationale is when the value reaches the DAC chips, most DAC will simply truncate those least significant digits, hence there will be data loss using normal approach. While a more "exact" value will have a better chance or retaining the whole value through the DAC process.

So basically, the volume values are represented by "as few bits as possible" to give more headroom for other DAC processes.

We've received overwhelmingly positive reviews from users - so much so, that many are choosing to sell their pre-amps and go direct to power amps.

It's no coincidence that this innovation came after we released our own power amp to be used directly connected to LUMIN streamers.
