A review of the MK2 Hiface has just been published in StereoMojo. An extract from the conclusion "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."
