CHORD ELECTRONICS DAVE

[ekfc63]

I also asked this on the TT2 thread. Has anyone successfully powered the TT2 or Dave off a Poweradd Pilot Pro 2 battery pack?

I did try a TT2 off a Poweradd Pilot Pro 2 battery and also an Mscaler but in both cases I decided that using batteries in a home system was not for me because of the faff or recharging and I no longer use them.

Regarding Dave, I am afraid you will have to explain to me exactly how you think you would be able to power it off a battery because it is not immediately obvious.

And did it work?

Its not for any performance benefits, just for use in certain one-off situations.

The pp2 does not have compatible connections for Dave. Yes a pp2 works with tt2 at 12v, if you want to use it in the garden, but it may invalidate your warranty.

Fixt it for you.

that’s right. Didn’t think my thought through before posting.

Is that definite ? Or is it only other non battery power supplies as I’m not totally clear on the point.

Using anything other than the supplied psu will invalidate the warranty if chord become aware of it.

I think that the only safe advice is that if an aftermarket power supply of any type or make is used and damages the Chord device then it will be perfectly obvious to Chord when they do a post mortem and they see what has caused the damage. Understandably all warranties will be withdrawn in those circumstances.

The poweradd battery is perfectly capable of destroying an MScaler or TT2 if used with the wrong voltage setting because the 16v setting on the poweradd battery supplies well over 16v. In those circumstances saying that RW uses one will do little good in warranty discussions. The 12v setting on the poweradd battery ought to be safe unless there is an over voltage malfunction.

My comments are not so much aimed at you Zappa rather for any others to understand that they are potentially on their own no matter which non Chord power supply they use. Snowflakes are better off using the Chord power supplies unless they are prepared to take the consequences.

As I have said before, the MScaler is rated at up to 16v but the 16v setting on the poweradd battery supplies well over 16v. In those circumstances saying that RW uses one will do little good in warranty discussions.

M Scaler is rated between 9V-15V. Rob has said more than once that he has the PP2 set to 12V when powering the M Scaler.

no, its ok, i use the supplied psu.

Does anyone remember what DAVE'S single ended max output at -3db is (DAC mode)? What volume setting would give me a maximum of 2v single ended?
Thanks
Marc

-3db is 3V so -7dB is approximately 2V

Thanks! I'm trying a Schitt Freya S preamp and it's distortion rises above 2v input I'll set Dave at -9 to be safe
I'm comparing a $14000 Spectral 30SV to the $700 Schitt
BTW Schitt's Asgard III headphone amp hits way above its price point

Dedicated analog pre with Dave is not required. It can be fed to a power amp directly. Even if pre or headphone amp is to be used, then use AAA tech based pre like benchmark hpa4 or AAA tech based headphone amp. There is no point in using a $14k pre after advent of AAA tech.
