Right, almost 10 years ago Gert built around 30 of these (https://www.avforums.co.za/index.php/topic,5864.0.html). Would be interesting to know how many are still out in the wild. Also the build thread is sparse on listening impressions other than "it sounds good" or "betters the Graham Slee". So ten year so, has anyone compared these to more commonly available amps like Schiit and Audio GD? And has anyone ever done measurements on these? Maybe we can send on to Amir?
