Interesting video, thanks for sharing!
I wish he would elaborate more on the "precision analog volume control" that is better than 130dBs though...
YesYou mean -135db, right?
I know the volume control in a Sabre DAC is awesome but I still want an analog volume control for analog sources..in the context of a Sabre based dac it is quite pointless to add an analogue volume control.
you should see the Accuphase AAVA volume control.In case of an active, low output impedance IV stage, the best solution is to forget about analogue VC or any kind of additional preamp circuitry. In some systems this may even be possible with passive I/V or voltage out solutions.
kinda makes me laugh thinking at the passive volume controls some are in love with. it also makes me wonder if sonic quality has to do with this choice at all.
...pretty hard to DIY something similar to AAVA. better to talk about how passive sounds better.
Is there a schematic diagram available for that AAVA?
I have the complete schematic, not sure if I'm allowed to post it (it's not patented etc).Is there a schematic diagram available for that AAVA?
I will post it if someone explains the policy for posting schematics of commercial production gear.
