Conrad-Johnson HD3 USB DAC

Hi diwakarv If you are running a mac like me I.e 2009 mini. I use a Paul Hynes linear power supply. He is the best but you end up waiting a year. Otherwise there are plenty other brands. Eg keces, teddy pardo etc. may I suggest checking out computer audiophile. Almost anything you need to know you find there.

Thanks Fand for the reply.
I tried IFI and it makes base enhanced but suppressed dynamics. I am not sure if the sixth order filter is affecting signal and it's harmonics too. I tried "power " only output too but it is not making difference. It is surely going back. I will check computer audiophile. Thanks again.

Hi Fand,
I am very happy with HD3 USB. Thanks for your suggestions.
Which route gave you more improvements :
a) Supplying Alternate DC ( through SR3 or Pedro ) to DAC through Y cable.
OR
b) Providing clean supply ( like SR7) to mac mini.

I am using macbook air.
Thanks

Hi diwakarv

For a while I was using a y type kingrex usb cable with a separate power supply (teddy pardo) and the paul hynes sr7 powering the Mac mini.

Then as an experiment I tried just using a single usb cable from the Mac mini and it sounded better. Much more bass andclearer midrange. So that is what I am doing. The really high quality power supply for the Mac mini is clearly the key to this. And a really high quality usb cable
