Hi, guys. I am new to this forum but now new to Hidizs

Own AP100 for a couple of years and now have AP200.
Here is my separate thread... I wish it were moved here, as a post.... Just first impressions and opinion... Sound tests are still in progress. (BTW - Ukrainian, Russian and English) - if some people from CIS need help.
Concerning the sound quality (just a brief opinion
First, I am using Yamaha RH-5Ma (mids and highs oriented, 32Ohms), Audio-Technica ATH-M20x (more bass oriented, 48Ohms) monitor headphones and Edifier R1100 active system (not bad at all if to use the triangle rule) to test... Ano some more stationary equipment... Most of the comparison concerns AP100 (075 off. released FW) predecessor because I've got used to its sound and would demand the same or better quality with the new AP200.
1. I like AP200 sound more. It reproduction of human voice is more natural. A bit more wide and standing out.
2. Highs are on par with AP100
3. Low frequencies are totally enough and feel very well controlled.
4. Mids seem to have more depth and width - especially evident with mid-drums where sound is a bit more reach and have more overtone.
5. In overall, AP200 sound seems to be more balanced in all freq, range. To get the idea: if we would assume that AP200 has a straight line freq response graph - AP100 would be closer to classic Rock EQ (while real EQ is turned off in both).
6. AP100 has a higher max volume compared to AP200 (even if gain set to high). Nothing to worry about with my headphones but I am not sure if AP200 would handle something above 150Ohms.
And a question: couldn't find the infromation about EQ. AP100 had a separate HW EQ chip, not sure about AP200....
