I bought the H/K 510 recently. In the DTS mode, there appears to be a much smaller LFE output level coming out of the receiver, compared to my previous decoders. In DD mode, the LFE amount seems to be correct. I have tried all the different settings of large/small and X-over frequencies. Does anyone else notice this? I am using the DTS demo discs and the Eagles "Hell Freezes Over" disc for monitoring. Thanks. BTW, I am using AVIA to calibrate sub-woofer level. Unfortunately AVIA only has DD and not DTS test signals.
