Tama si anya618. We do not just jump into conversations, giving feedback basta-basta.
"Expert" feedback must come from actual owners, or people with actual experience handling the same unit. Wag ka agad mag-tampo, malas lang siguro at wala masyado pa ang may LE7M, and kung meron man, hindi pa nila na-e-experience ang problem mo.
SnS offers professional calibration. There will be very few who are more "expert" than them. Go give them a call. Sa kanila pa naman nanggaling unit mo.
