Hi all! I have this setup: - Yamaha RX-V650 receiver. - Pioneer DV-575A DVD player. - Two pairs of Wharfedale 9.5 floor standing speakers (front and surround) - One Wharfedale 9.CS center speaker (placed directly below the TV). - One Wharfedale SW150 subwoofer. - Chord Carnival Silver Plus cables on all channels. - Supra Trico digital coaxial cable connecting DVD to receiver. My problem is the dialogs sound very low during movie playback, in either Dolby or DTS. With many movies I have to level the sound at around -20db so that I can clearly listen to dialogs on more silent parts of movies. Well, actually some movies I need to level the receiver at -15db This is a problem because on the loud parts the sound is just too loud. Very very loud if there are explosions or gun shots. I have to keep adjusting the level during movie playback... I already set the center channel speaker level to +7db (the fronts are at +1.5db) and this has helped a bit, but still it seems like the sound from the center channel is much weaker than the sound from the front speakers. I read somewhere that this is a problem related to the receiver power output, or something like that, and not so much a problem of the speakers. Should I just get another receiver? I'm testing the Presence Speakers option, by adding two additional speakers above the TV, and configuring the receiver to use the Dialog Lift feature. This does help, but to use this feature I must select one of the DSP sound programs, which are fine, but I feel lack in bass making the sound feel a little bit less stronger. Can DSP modes be corrected to sound more like Dolby/DTS standard sound, and still take advantage of the presence speakers? Any ideas? Thank you very much!
