Have you tried setting display to 4?
Does it help?

Oh yes. Display 4 fixes the issue. 90% better. In normal volume ranges completely silent so no worries. Just curious. Non issue.

So there is still some noise even with display off?

Then there is something more happening in the system that Feliks is catching something and amplifying.
Some ground loop maybe.

ps. can you try different dac? Also as I see you are using farad3 with Dave - can you switch to stock ps just to see if there is difference?

I have just tried with my Dave with the display on and off and the volume turned up to max (+19dB). It is totally silent on its output even when the display is on and the volume is at max. I don’t know if you using the Farad power supplies has any impact on what you are hearing? (I have the Sean Jacobs power supply with my Dave).

DAVE with Farad power supply through Feliks Envy Amp (with stock Tubes) is silent on all display/operational settings. Volume turned up to just over 4 O'clock (no music) is where I start to hear a very minor start of humming. No way would I reach that 4 O'clock level level when listening to music. I barely go beyond 9 O'clock on High Gain setting on the Envy.

Earth it and its gone.

I use tube mundorf angelique rca cable when it occured and indeed only when the display lights up. Other shielded rca that sounded worse or earth wire fixed it. So option two

I was thinking of getting something like this ...

Edit: Sounds like you had the same exact issue as me. Crazy

Try a simple wire to dave and grounding and its gone.it comes from the display chip thingy icw the unshielded rca input and prob some noise that bounces in that kind of situation. But thats were groundings are for so fixed.

apparently the dave would clip at plus 5 with the m-scaler or plus 3 with the dave alone

Well If you want to know impressions from someone who currently owns both, feel free to Pm

Will do. Admit it was silly of me to ask directly in this thread.. sigh lol

"Mscaler is imho the most important ingredient in the "Rob Watts cooking recipe",

Yup, I would agree with that. I've crossed over to almost not being able to listen to music without it. It's frighteningly like a drug.

I don't know about most important, but having shipped my M-scaler to my new destination while only using the Dave in the meantime, the lack of additional layering and spacing is definitely apparent (like.. very apparent). I'm not sure it's a "must own", but it certainly seems like a "can't sell or get rid of", which I guess is essentially the same lol

I wasn’t playing music, just listening for any background noise from the display. It was silent.

Earth it and its gone.

Just curious, if we have a lighting storm and I have the Dave connected to ground, is there any potential issues with electricity spike? I assume no but wanted to check. I saw some ground cables had a resistor.

 

[MvRBE10]

No thats were groundings are for to remove noise and voltage peaks etc. Asumong your house earth is a ok. But with an direct hit you orobably have other issues to handle.

To those who are - like I was- petrified by all the "you want to switch all the capacitors out of the DAVE with platinum/uranium ones hand-wound by blind monks" and "to block RF you need to battery-power everything in your neighborhood and cover your house in 6 layers of lead" kinds of talk I can very happily report that I'm listening right now to a DAVE connected by all stock cables to a Macbook Pro and MScaler listening to, of all things, recordings off *Youtube* (what are they, 128k .mp3 or something?) and it sounds just ridiculously amazingly good. Like "can't leave the room" good. (Though interestingly the DAVE did seem to need a few hours burn-in before it got completely up to speed).
And don't get me started on how good it sounds with Audirvana.

Thanks to @Rob Watts for your fantastic work.

Still ... all the other tweaks help it sound even better hehe
