i recently bought the ONKYO 510 speakers from circuitcity. i want to get a nice receiver to go along with it. i always wanted to buy the ONKYO HTS-760 home theater system. can someone tell me how the pioneer 812 receiver compares with the ONKYO 510 receiver that comes with ONKYO HTS-760. the ONKYO 510 receiver has 0.08% THD whereas the pioneer 812 has 0.2% THD. which one is better? also, how does the pioneer 814 compares with the pioneer 812. one difference that i see is that the 814 has a DAC of 192KHz / 24-Bit whereas the 812 has 96KHz / 24-Bit. is this important? thanks.
