Thank you.mark and study.

I noticed there are two Mac mini upgrading service website: core audio and mojo audio. Last week I listened the mojo version 2 linear power supply modified Mac mini 2011 version which equipped with Audiophilleo 2 pure power . I compared it with my own 2011 Mac mini withAPPP ,found the PSU very effective and positive. Does anybody know any one of the above both? Who is better?

I was told by a guy that wadia27 DAC is in the position to be a direct link into power amp. sure i wll lost my wages to have a wadia27.

And,I just bought an audiophilleo 2.It defeated W4S USB asynchronous interface，greatly improve sound.More clear inmage,fine details.

It has rather good dynamics and fine details. Power play a very important role in DAC performance.I use a 6MM2 private power cable and matched with Furutech GTX-D® and Wattgate 381(AG) and (AU) wall plate. Connecting DAC2 direct to wall plate makes sound much more fresh and vital ,comparing with connecting power distributer. So,I belive poor power feeding may let you misunderstand your DAC.
