I realize that the Integra line, when compared to B&M Onkyo receivers is similar to comparing a Lexus with a Toyota. Built by Onkyo, yet with better components (so they say) Does anyone have experience with the Integra lines to offer a fair assessment of this brand of receiver? I am trying to compare the Integra DTR-5.4 with it's little Onkyo brother, the TXSR-601. The look and exterior features are nearly identical. Are the internal components worth the nearly $100 difference in costs?
