Yes we should have some news in 1-2 weeks


Nice! Out of curiosity, should we expect the Nirvana to be able to power the full stack (i.e, would we plug it into both the Katana ucontroller and the Isolator)?

This is not Nirvana but our LPS with 2x 5V output at 3A and 1A
On LPS last test data shows we have reached 80nV of noise 0-30Khz (audio band). That makes it the lowest noise power supply in the world.

Nirvana new PCB will reach next week and we will test. We are expecting at least 3uV of noise on this SMPS

Dear allo,

If you have LPS this good, why building switching one (Nirvana)? Won't it be necessary worse? :roll:
Thanx

SMPS will never be as good as a properly designed LPS. Also the price point for the 2 PSUs is different . At last the LPS has 2x5V output while SMPS will only have one.

dear all,

Do you know if we have the chance in the future to get a stand-alone Katana equivalent with classic inputs (USB, coax etc.)?

Thanks for your help (and opinions)!

Best regards from Munich

Dear allo,
are you considering making a katana board with digital input (e.g. coax, toslink)?

If yes, it will be
  1. standalone product, or
  2. extension HAT which could be added to the existing Katana v.1.2 stack?
  3. Or any other concept?

Thank you very much for answer,
pista

Any thoughts on when the LPS will be back in stock on your website? And, are you making any revisions to it?

I just got my set of Katana sound quality + isolator, I am using SMPS to feed RPI and Katana, already very very good sound quality, very GOOD JOB from Allo!! Can sell this DAC in such low price!

Time to gather some market research. I would prefer a 'Katana lite' , re-use the Katana DAC board with a new micro controller-output board using monolithic opamps( less heat than class A). Isolator can still be an option, and the new dual LPS from Allo would provide clean power. Now you have a simple to use streamer-DAC thats plug&play. There are plenty of DAC's in the price range (Khadas tone board, Topping D10/30/50 etc.) that perform well, Allo needs to differentiate itself from the competition. :idea:
