I am with wombat on this. Once we have figured out what DACs at different price buckets measure well, there may not be much more ROI for you, Amir. But it's your time, your site, so I can only suggestI am getting extreme pressure to measure Topping D50 and a few other bits. Folks know where I live so my life may literally be in danger if I don't test their stuff!!!![]()
