Unbelieveable for price! by L. Smith
I was really torn about getting this vs. the 608, but after reading about some issues with the 608's signal processing, I decided to save some dough and get the 508 (I really only need 2 HDMI inputs for my media room anyway). Boy am I glad I did. I used the microphone Audussy II tuning feature, and was completely tuned in 10 mins. I have a Panasonic ae4000 projector, and on a 11 foot screen, this is like IMAX at home (BETTER!). The sound and picture are absolutely incredible (the PS3 is one of the best Bluray players out there, so you do not need your AV receiver to process the signal). I can't believe how powerful this 80 watts per channel sounds on the inexpensive BIC speakers I purchased at Amazon (DV64, DV62, V-1220, and HT8W). The room is 15X20, and I really can't turn up the volume above 65 without it being too loud (60 is about right, but loud; 100 is max). It also made me realize how UNcalibrated my Denon 1803 without Audussy is in my living room. On the 508, I can hear the dialog perfectly - even in low volumes; I have to crank the old Denon, and I still have problems hearing speech clearly. For 250 bones, I am seriously thinking of getting another 508 for downstairs. The AV pairs perfectly with the PS3 via HDMI, and I have not had any problems with it being able to pull the sound from the Bluray in lossless form (dolby true HD). I really don't understand how this thing can be so inexpensive.



On the downside: if you are connecting to a TV, you will have to power on the receiver to get the HDMI signal to pass through - not a concern for me since a projector does not have its own speakers - but if you want your TV speakers only (maybe to save electricity), you will have to run another cable directly from your source to the TV.



Secondly, I noticed it getting very hot when placed in an enclosed cabinet (open in front with holes in the back and 2" clearance around). I ended up cutting a hole in the back of my cabinet, and attaching a cheap computer fan blowing out. This completely solved the problem as it runs very cool now - even for 8 hours cranked - without any noise. I suspect many failures noted here may have to do with placement and overheating.



All in all, an unbelievable bargain!
