Replace with an amplifier that can decode HD audio..
Any brand also can, not necessary Pioneer.
Because amp is the heart of HT..u should at least get a mid-range to high-end model.
A good powerful amp can work with cheaper speakers BUT a good quality speakers cannot work with cheap and less powerful amp.

Currently I am using blu ray player to decode HD audio and pass to my AVR using LPCM. Just wondering, even if i were to buy the latest AVR that can decode HD audio, would it really make a different?
Below are what I have copied from Pioneer website, to utilize the technology such as Phase Control (which available in Pioneer AVR also), ABD, AFAST... Do I need to buy a Pioneer AVR?
High linearity port structure for deep and clear low frequency sound. (SS-31-LR-K/QL)
ABD and AFAST Technology (Patent pending) for standing wave control. (S-31-LR-K/QL)
Flush-surface design and round form enclosure for aesthetics.
Phase Control design for a dramatic improvement in multi-channel sound quality.
150 W (RMS) subwoofer for deep bass. (S-51W)
