In BTR7, my PEQ settings was deleted by itself, I had to set it up again, also it changes some PEQ settings by itself with different settings. It is not stable.
These are the bugs I've seen so far.
Also, PEQ is missing special filters (compared to Qudelix 5K), which is a big shortcoming in this price range.
There have been many software upgrades for BTR7, but it is still a big shortcoming for PEQ that they do not fix the problems compared to their competitors.
Note: I bought BTR7 because I couldn't find Qudelix-5K in my country. If I can buy the Qudelix-5K, I can sell the my BTR7.
