Extract from TirnaHiFi.org review:
Well, the space and resolution around individual instruments and singers was improved, which led to a much better appreciation of the soundstage. Better depth, width and height were readily apparent. I could detect no downsides to this: there was no trace of any kind of glare or harshness, listening fatigue never set it. In fact this unit was responsible for more than a few late nights chez Morrin. A curious thing: I found myself not needing to turn up the volume to hear small details in the recordings. These improvements, coupled with the neat box it’s now housed in, and the built in charger, all make this a significant step up from the Mk1.
I can comfortably recommend Johns mods to the HiFace to anyone interested in getting the best sound from their computer-based source. In a word, it will change your perception of PC as source – and at a very reasonable price. Now there’s something you don’t often read!!

"The Mk1 modded HiFace didn't just give good performance for PC based sound - it gave good performance, period. I was lucky enough for John to also loan me a Mk1 again with the Mk2 so I could directly compare one to the other. Well, when I tried the Mk1, I remembered quite well the original sound - clear highs, tight lows and a really good clarity. I listened like that for a few days. Then I swapped in the Mk2. Now I could see why John was excited about the new mods: yes, there is a definite improvement with the Mk2. So what changed? Well, the space and resolution around individual instruments and singers was improved, which led to a much better appreciation of the soundstage. Better depth, width and height were readily apparent. I could detect no downsides to this: there was no trace of any kind of glare or harshness, listening fatigue never set it."
