You could try a battery, Andy. There are quite a few good ones around, which will outperform the stock SMPS unit. Hope you're enjoying your RPi :)

Got this one recently. It seems to work fine. I was using an Aqvox linear psu before on last unit, but decided to try one of these.
I tried a battery for a couple of weeks but found the sound a bit too bright and lacking in bass. I am now back to using my maplin power supply and sbooster and I am far happier with the sound, for now. The problem with this dac/pi combination is there are so many settings for dsp and upstampling you can try.
All, we will be receiving another batch of Pi-DAC+ in the next few days. These will be placed on the www.iqaudio.com web site along with cases etc.

Not sure that configuration flexibility is a problem as such...however after running with 24/192 SoX upsampling, at the highest settings for a couple of weeks, returning to 'bit perfect' (16/44.1) has reminded me not to dabble with up-sampling, there is more bite and attack with up-sampling turned off...KISS (note to self) :)Quote:

OTOH the DAC chip uses a charge pump to general its negative rail, so it's hard to get away from switchers of some sort!
BTW I am very impressed with the SQ of the PI2/IQDAC+ combo. Better than Benchmark DAC2 HDR, Aurallick Vega, MDAC and a couple of other pricey DACs I had at home. All the expensive DACs I tried used ESS9018 - this makes me wonder about the 9023.
Would someone be able to summarise the findings, conclusions or even the current consensus thinking on this thread? I'd like to take a step into this but haven't got the will or patience to trawl the 1,500 posts.
Many thanks in anticipation.
