If the tuning process feels too confusing, I know I may not get the best sound out of it. Simple and responsive controls make a big difference in my experience.
My Budget Thoughts
I always compare the price with the features I am getting. A 10-channel DSP can be a worthwhile investment if I want advanced tuning and a high-quality system.
