Have firmware updates corrected issues with Qm8k and Qm9k? Opinions on upgrade route?
After all the firmware updates where does the Qm7k, Qm8k, Qm8k stand? I have the Qm7k beautiful picture but I'm doing an exchange/upgrade due to buzzing issue to a Qm8k but thinking maybe I should have jumped up to Qm9k. After updates all issues should be fixed correct?
