I have long suspected my inexpensive receiver (Panasonic SA-HE100) to be the weak link in my system, more specifically, the bass management (or lack thereof). The crossover in my receiver has only two settings, 100hz and 250hz. There has always been a hole in the frequency response.
This evening I decided to experiment. I moved my PC into the living room and connected my Audigy sound card via analog into the 6ch input on the receiver, bypassing the receivers bass management and allowing me to use the options provided in the Audigy control panel.
I was able to set the crossover in .10hz increments. I ended up at 80hz. The difference his huge! The sound is much more full! I cannot believe the difference. While changing the crossover setting the difference is very obvious. With the crossover set at 100hz there is a point during a frequency sweep that it is nearly silent as it crosses from the sub to the speakers. When set at 80hz the response is audibly flat (I don't have an SPL meter).
The D/A converters in the Audigy also seem to be FAR better than those in the receiver. I have had my PC connected to the receiver via coax digital. I though that sounded good. The sound from the Audigy's analog outputs is simply stunning. I did an A/B test using my DVD player (via TosLink) and the PC playing the same song (ripped in uncompressed .wav). The difference was unbelievable! I never knew I was missing out on so much.
I'm really itching to buy a new receiver now. The Yamaha HTR-5860 seems to be the best value. I has good bass management features, better amps, and auto EQ. Is there any reason I should not go for it? Would the DAC's in the Yamaha be better than my current receiver?
