Would your friend care to publish those results on this or the Qutest thread so they can be responded to? .5 of a bit is an interesting concept. And since a Qutest isn’t a DAVE, and an MCRU power supply isn’t what the guy is thinking of buying …..

Again I asked for your listening impressions please

...similarly, I preferred the Qutest on a Farad3 vs. stock. HMS too, come to think of it. Heresy! Wait, that's a speaker...

Fwiw i preferred the stock psu on the M-scaler vs the Farad. And a battery is much better than both.

...batteries get good reviews, even from the creator fella.

Speaking about power supplies, does anyone know where I can get one that can accept 100 - 230v input, and the dc output needs to be 16.8v with 2.5amps.

I can find the 16.8v part, but I can only get 2amp versions. Help a brother out peeps, I will make you rich if you do.

As someone with an interest in batteries to avoid going down the route of expensive psu’s, special electrical chords and re wiring the house, I know nothing about what batteries to buy or what qualities/specs to look for. Happy to hear any advice you (or anyone) can offer for a Chord DAVE.

Another query I haven’t seen answered yet too is the need for selected dual BNC isolation solutions that break the RF loop when using expensive power supplies, powering one component from a battery takes care of that one issue, surely such an expensive PSU would break the RF loop also ?

I fear my listening impressions would be of little value since we surely use different electricity suppliers. Maybe even different mains frequencies and voltages. And I’m still trying to get my head round one and a half bits.

I’m pretty sure plugging equipment in different outlets on a PS Audio powerplant accomplishes this

Hi guys some advice please. I’m having my Dave upgraded with a Sean Jacobs power supply. I’d like your advice optimizing it. For the last 4 years I’ve been using an Aurender N10 with the spdif fiber optic output sounding the best to me. It seems a lot has evolved in the last 4 years, pggb, usb etc. What server would do Dave/SJ justice? What interface is optimum now? Thanks in advance for your advice and experience.I should add 99% of my listening is with loudspeakers and speakers that cast a large soundstage. Enlarging the sound stage would be a detriment increasing prat, detail, naturalness is what I’m after.

I would keep the Aurender N10 with the spdif fiber connections and get a Mscaler and Opto-DX. In my experience if the Dave, Mscaler and digital source components are placed a few metres apart, the quality of the digital source component is not so important. The Opto-DX allows separating the Dave, Mscaler and digital source. I use 3 metre premium optical cables. I have also installed separate digital and analogue power cables, wired back to the consumer unit. My Dave is located between the Heisenberg power amps and loudspeakers at the front of the listening room. The Blu2 and digital source components are located along a side wall. This layout also allows the use of short analogue cables. You will not be disappointed with the Sean Jacobs power supply. The ARC6 significantly lowers the noise floor, allowing details and threads in the music to be heard more clearly. There is also a dramatic increase in bass weight and resolution. The sound is also more 3 dimensional and it is certainly more enjoyable.

Can you please advise what optical premium cable you are using. Just interested to know as I like your thinking in the rest of your set up. Thank you in advance!

I’ve had very good luck with lifatec tos cables

There are posts on audiophilestyle of significant battery arrays being used to power a Sean Jacobs DC4 in order to power a Dave but none has attempted to drive a Dave direct from batteries and I suspect that is a fools errand. The Sean Jacobs ARC6 was created in order to surpass using the battery arrays to power the DC4 and the consensus is that the ARC6 succeeds in being better than battery power to the DC4.

This post is a good place to start . .

The premium optical cables were supplied with the Opto-Dx. I upgraded from the standard optical cables. Checkout the Opto-DX website. https://audiowise-canada.myshopify.com/products/opto_dx. Note also that 4 x high quality bnc digital cables are required for the Opto-Dx receiver and transmitter. I use 4 x 1.2 metre long Oyaide DB510 BNC cables.

Quite possibly, but not what I’m asking in regards to dedicated high end power supplies …
