See my other post today. Regen addresses the noise created at 8khz by the usb protocol itself. Nobody else does this. Only the Uptone Regen does this, that's why it is unique.

Hi and thanks again.
I am a little puzzled ... i read of a usb dac (the Lampi) that is the end of the world.
And i guess also extremely expensive (do not know the price).
and still a 175 dollar device elevates its performance.
They squeeze the last drop from a dac and then they connect it to the computer with an intrinsically flawed usb connection ????
I wonder we all know what is good and what is not ?
we really know what counts and what is marginal ?
Asynchronous usb transmission has been marketed as a godsend freeing from jitter and clock issues ?
and now we discover that is the classical can full or worms ...
I give up and for now i will wait ...
Maybe in some years time the scenario would be more clear.
Thanks again.
Kind regards,
bg

I think you are over reacting. Nothing is perfect, yes even usb. But to the extent that a particular noise source can be identified and reduced significantly is not a condemnation of usb. It's a cause for celebration. Other means of connecting a pc -> dac (spdif/toslink/ethernet) all have their limitations as well. In fact since Ethernet sends data in packets like usb it is also subject to packet noise.

Never listen to the marketers. Listen to the engineers.
Hi and yes you are right ... i over-reacted
But you talk about " the noise created at 8khz by the usb protocol itself ". I guess this noise should show up in some measurements
Instead i see many usb dacs with impressive low noise throughout the audio band.
Should i not see some peaks around 8kHz in the noise graphs ?
Thanks again.
Kind regards,
