My opinion about this is a little different ... I feel it's a good bet that audio equipment provided with an SMPS, class D amps included, are designed to work well with SMPS noise. So I wouldn't worry about the Touch power supply on its own.
However, I'm not happy to make that bet with audio equipment using linear supplies. Therefore, if your outboard DAC, amp or actives use linear supplies, it might pay to address ALL sources of SMPS noise on the mains ring they are attached to. To filter SMPSs on the ring I use two phases of filter in series, a Tacima CS-929 and Marmitek FM10U. I have filters in the study (which shares a mains ring with my main system) and filters on the Touch power supply. My DAC and actives are plugged straight into the wall - it's the sources of noise that are filtered. I did the above, plus I bought better extensions (nothing audiophile, just branded lampless, switchless extensions), plus removed silly stuff like LED lights that I had plugged into the hi-fi extensions. Those that believe in clean power will gasp at the last bit, everyone else will say so what! Well I am a believer now because I perceived an improvement in sound quality mainly around "glare", "treble hash", "annoyance", "musicality" that is no-going-back for me!
