New Revolution PCB was populated today and testing will start on Monday. I should be able to send samples before the end of next week for SQ assessments .

Will your finished DAC have a volume control, maybe a screen?
What type is the usb input? It doesn't look like a type B connector.

May I ask why Type A?
IMO, Type A tend to be loose fitting.
Why not Type C or B?
Thanks

Matt

I don't have a Sparky so can't compare. Currently it's just hooked up to my Klipshh 2.1 desktop speaker system but at some point, after I ship moOde 6.3.0, I'll connect it to my Yamaha 2.1 Studio monitor system and dig in for serious listening and lightbulb loosening bass :-)

Please keep us informed about your impressions with the USB Sig in your big system.

May I suppose we can get it from Allo with moOde 6.3.0 in October?

Thanks

Matt

I think Allo is currently offering a moOde 6.2.1 image with enhanced driver etc. The 6.3.0 October release will be an in-place update and contains some nice enhancements to the Library, bug fixes and a few specials for the SIG :-)

Default USBBridge running with piCorePlayer!

Many thanks to @Paul123 and the PcP team! I've got a USBBridge Signature setup running with their distro/SW combo.

They've added the ASIX Ethernet/USB driver(s) to their latest betas available here:

BETA: piCorePlayer6.0.0 - PI4 support

I'm using an Ian Canada GB FiFoPi / ES9028Q2M / IVStd stack as a test bed (Its a bit simpler setup than a Katana physically and in PcP, trying to limit variables for any troubleshooting needed... but it all worked right away once I used the new beta).

After less than 2 hours run-time, the setup is sounding VERY good with deeply dark and quiet backgrounds and a very dense, artifice-free, and articulate sonic presentation.

My initial impressions are that this setup will beat the same stack on one of my linear-regulated-modified RPi 2Bs using LDOVR.com's Mezzanine board, which themselves are a good step up from a stock RPi.

Power is my latest best setups... 2 DIY'd point-to-point Ian UCPi 2x350F Ultracap pair supplies float-charged to 3.3V by an Uptone Audio LPS-1.2 off-the-grid Ultracap supply on each. The USBBridge Signature is powered from another 2x350F Ultracap pair float-charged to 5V by either a Shanti or a modified K&K Audio Low Voltage supply. The output IV stage sports a pair of dual Sparkos discrete opamps and is powered by the +-13.2V outputs of Ian's LiFePO4 supply.

The 350F Ultracap pairs with the same float-charging scheme at 5V are working well on my main Katana setup too. I have yet to try powering the Opamp board with Ian's LiFePO4 supply, I'm expecting good results, perhaps next weekend.

I'm doing some component trials on my main Katana setup, which should be done this weekend. It'll go onto another USBBridge Signature then. I can't wait!

I believe Allo has another winner here! MANY THANKS Ioan and the rest of the Allo team for making one of my dreams come true!

Greg in Mississippi

P.S. Sorry for the busy picture... my power supply configurations are getting more complex with every iteration.

Greg,
thank you, VERY impressive!

Now I am looking forward to a review where the SIG is powered by a Shanti only and feeding a DAC via USB.

Sure, no problem. When you are ready.
As for the usb connector I hope you will reconsider that typeA and go for a typeB input as most DACs do. And -why not- because some of us already have nice A->B usb cables that would want to reuse
Good luck with your projects, sir. It seems that you are not wasting your time.
