CHORD ELECTRONICS DAVE

My DAVE may have a $50 power supply but who cares when it sounds soooo good

In fact I was wondering why some have more satisfaction from the headphone output than others.

Maybe that's why I get to push the Abyss directly from DAVE with great satisfaction.

Also, with the battery as power supply, the volume can go up to infinity...

wow.... Dave powered by battery, which one is that?

You can find information in these previous posts of mine: 22.679 - 22.705 - 22.718

The battery was made especially for DAVE.

It is not found on the market but must be made by a specialized company. It's not easy to find someone willing to make it for you.

The two batteries are hidden behind the support surface, with the relative automatic recharge circuits.

You might want to mention too that your Dave is running on 160v DC power which is free of switching noise

In the old posts that I have reported everything is explained.

And so, after learning that it was possible, here is DAVE powered by a 160 VdC / 3.5 Ah lithium-ion battery, without any inverter.

Operating voltage: 160 (max) – 120 (min) Vdc.

BMS for charging management and protection, designed free from EMI/RFI emissions. Outgoing have been put Neotech solid core UP OCC cables.

Like the other battery I use for the streamer and the MScaler, a double timer disconnects automatically at set times the charging from both the socket side and the battery side plug, completely isolating all audio components from the mains while listening and reconnects at night for charging, resulting also protected from possible thunderstorms or overvoltages.

It was delivered to me a few days ago, so I'll update with further comments regarding the audio result.

Would anyone who is confident, be able to highlight the necessary components from mouser or farnell to allow others to try to assemble it ?

Sure! The timer and charger can be ordered on eBay.

The most complicated thing is the large lithium battery which must be made by a highly specialized company.

I can also tell you the company that made the battery for me. I think he has no problem building a similar one.

Good man, then I’ll share with the thread lol. I think it may not be practical to ship a battery from Italy to the uk due to restrictions. But maybe I can find someone local…

Wow this is amazing. The passion people have for the DAVE DAC is truly amazing.

DAVE is a keeper. Integrates well with Naim gear and a real foot tapper, very hard to pull away to do household chores
The MScaler adds too and to my lugs an element of analogue replay, great combo by @Rob Watts
