I have to wonder what s "Ultra-Expensive"about a software that cost at most 650 Euros
Marty's system is not what I would called "Ultra-Expensive" either in the context of >$200K speaker. In fact many of the DSP proponents systems are "regular"
audiophile systems, nothing that those most vociferous against haven't spend much more on cables or just one single component sometimes
The thing is that our prejudices as audiophiles are deeper than we are willing to acknowledge. Changing our views and positions on certain things is close to impossible even when hit with a bat with the evidence. DSP (We all understand what it is after all, regardless of claims of the contrary) is in that category for many, it also commits the cardinals sin of being a digital solution a PCM only to boot not the less sinful DSD.
