I've gone partway down the rabbit hole; okay maybe more than half way down.

Office system is Drop THX 789 with HiFiBerry DAC 2 HD on raspi 4 with display.

The PCM5122 is an attractive chip with integrated line driver which simplifies the output stage so I can see many inexpensive HAT boards going with it.<br /><br />2. Right. In fact, even something ultra inexpensive like the SMSL M100 Mk II (<$100) I reviewed a couple weeks back will perform well and even has S/PDIF Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-58909507225516701332021-02-20T09:16:12.243-08:002021-02-20T09:16:12.243-08:00Hi Deadushka,

As you say, the PCM1796 has been around for far longer than the DAC+ Pro. When they designed the DAC+ Pro, they <em>could</em> have based it on the PCM1796 instead of the PCM5122. Instead, at the time, we got a whole bunch of look-alike PCM5122 boards (from Hifiberry, distlerhttps://www.blogger.com/profile/05285712234491092112noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-52383672788267007022021-02-16T05:46:30.748-08:002021-02-16T05:46:30.748-08:00Hi Archi,

And the difference is very obvious. Is there a chance to compare these in numbers (or is it just my imagination).<br /><br />My system consists of a Deadushkahttps://www.blogger.com/profile/11660008273105538826noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-52143327733795984802021-02-14T08:44:11.019-08:002021-02-14T08:44:11.019-08:00It truly is impossible of course to not have "...It truly is impossible of course to not have "diminishing returns" if we're talking about sound quality.<br /><br />Human hearing obviously has a physiological limit so it follows that ultimately, regardless of how much money we spend on something, we reach the point of "transparency", there is nothing left to achieve!

I suspect this is due to advancements in both power supply technology even when cheap and how well the boards deal with filtering out the noise these days.<br /><br />I have no evidence to say that linear power supplies are any better Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-60624204266815542722021-02-13T10:45:12.578-08:002021-02-13T10:45:12.578-08:00Hi Mark,
