Wow thanks for your input. Just to make sure, which voltage/connection did you use from that Pro-ject Power Box? 15V?After a few weeks of testing the power on the ADI-2 with its original power supply and the Audiophonics 90 Euro linear power supply it was a toss up between them. With some songs I'd prefer the original psu, with others the linear one. That really shows how good the psu that comes with the ADI-2 is. For example with other dacs, Qutest the difference was obvious between the switching mode psu and a linear one. I also really love the the RME has variable voltage, between 9v-15v, that makes things much easier.
But apparently not all linear power supplies are made the same. Found that out after buying the Pro-Ject Power Box DS 2 Sources and comparing it with the Audiophonics one. Of course the price difference is huge between them, but in the end for me it was worth it. So how is the Pro-Ject linear psu compared with the stock RME power supply? Well now the difference is obvious from the first song, the linear psu is much much better. The sound becomes thicker, with more texture, the voices have a better impact and the biggest difference is with the instruments, they sound a lot more lifelike now. I hate to use this word, but everything sounds more 'analog' now. Thats the best way to describe it.
The RME ADI-2 with the Pro-Ject Power Box DS2 is on another level, didn't think that was possible since the RME was incredible already with its stock psu. If you are chasing the last %'s of sound quality like me buying the linear psu was a no brainer. This is my personal opinion, and all of us have different hearing and tastes, but with a good linear power supply the ADI-2 becomes sublime. The difference is so profound that I could never go back to stock. But if you already enjoy the stock psu sound ignore everything I wrote, your wallet will thank you later.
