I'm leaning towards buying the Denon AVR-X2000, but the Onkyo TX-NR626 is still lingering in my mind.
I have a question about the differences in how each receiver amplifies their inputs.
The Onkyo "employs WRAT, 3-Stage Inverted Darlington Circuitry, H.C.P.S, and Optimum Gain Volume Circuitry for dynamic, detailed, clear sound."
While for the Denon "The power amplifier circuit adopts a discrete-circuit configuration that achieves high-quality surround sound reproduction. To faithfully reproduce the original surround sound, each of the Denon AVR-X2000's seven channels are equipped with its own high-current power amp of equal power. Since these power amps also use discrete circuits configured with parts strictly selected for their contribution to high sound quality, rather than with low-cost integrated circuits (ICs), the surround sound playback is of impeccably high quality."
What will be the potential differences in what I hear?
I would buy the X2000 as it is what I currently own because of the only Onkyo product that I ever owned, a 709, died 14 months after buying it. Its HDMI board melted down and took almost 2 months to get fixed after I had to deliver and pick it up 70 miles each way from the only authorized repair shop that Onkyo would send it to.
Knowing what I know, I would pick the Denon X2000 100 out of 100 times..........Good luck!
