Smile the best volume control

I 've just finished my Muses Protos for the first listning test.
It sounds great !! the best Volume control i've ever used in my Preamp.
I use two Muses boards with low noise LDO (TPS7A49, tps7a3001) for full symmetry
The Muses is buffered with Cascoded FET Buffer with DC-Servoloop and a OPA1632 gainstage.

Very interesting.
How about schematics?
Or will you make a kit available sometimes?
If yes, I suggest to separate display and rotary encoder to have more freedom for frontpanel design

Yes, a kit will be available in about 2 weeks!
The boards are in production now and we are still working on our webshop.

The schematics for the modules will be also available on our website.
Please be patient, i'm still working on the documentation.

You can use a second rotary encoder connected with an ribbon cable anywhere you like it.
This mcu board is also designed for other kits, wich will be available soon.
(e.g. SABRE ES9112 ADC Kit, ES9018 DAC Kit).

You will offer a ADC-kit with a Sabre-chip? This is exactly what I am looking for since several months!
Question: is it possible to have the input selector with MUSES-chip and OPA1632-stuff in front of the ADC according to standard ADC-applications (I have no datasheet from Sabre ES9112)?
And: where will your kits be produced? In Austria or Far East?

Default Muses on Sabre ADC

hi hm4nine

Yes, but it still takes a little time until the final ADC boards are finished
I once built two of my Sabre ADC without a muses and it works fine in a recording and mastering studio.
Now i see , that it is essential to adapt the input level and i plan to combine the muses with a fet buffer and an OPA1632 to drive the ADC.
Maybe an Input select for two diffenrential inputs or a route through will be implemented.
The datasheets of the Sabre chips are confidential.
The production is in Austria.
