Mesch - I’ve just been reading about the Audiophilleo product range and it looks very interesting.
I would agree with your assessment, but only if the Pure Power option is used.
The Doukmall cable addresses one basic issue...
- IF your DAC utilizes the "unstable" power normally supplied via the cable connected to the computer - (many do not, so it is not an issue) you have the option of connecting it to a separate "clean" power supply.
The Audiophillio Products with the Pure Power option will also alleviate this issue - i.e. by NOT using the power provided via the USB port.
THEN - they go to some extraordinary lengths to ensure extremely clean power is supplied to the digital circuitry.
However, if the Pure Power option is not used, the Audiophillio USB-SPDIF Converter uses USB power. In which case, it too is subject to the same issues any other USB powered device is subject to.
- In this scenario the Doukmall Cable along with an Enercell power supply will be of benefit - but probably not as good as the Pure Power solution.
Personally, I have tried many "experiments" with providing "clean" power - especially to digital circuitry and found it paid big dividends in SQ every time and the Audiophillio products seem to be addressing this to the highest order.
It would be very interesting to hear Audiophillio + Pure Power compared to my Doukmall setup - I would imagine the sound is very nice indeed - alas, the price is the only thing stopping me.
You wouldn’t happen to reside in the Toronto area would you? :-)
