With any discs with both DTS and DD soundtracks, I've always found that the DTS version lacks deep bass, and have always been surprised when reading reviews that state a preference for the DTS soundtrack due to deeper LFE. I recently got hold of a DTS setup cd, that contained DTS music and some test tones. Having never been able to use DTS test tones before (and always setting channel levels with DD material), I did indeed find that the LFE channel needed to be increased by about 10dB. My suspicions that the amp was not applying the correct +10dB to the LFE signal in decoding were confirmed. They had been arisen as I had noticed that, along with the audible difference in deep bass between DD and DTS tracks, the newer Denon amps have an LFE setting to alter the LFE level by 10dB for different playback modes. This was also confirmed by the fact that the DTS music sounded correct on the A10SE at my normal settings (as DTS Music does not require a +10dB of LFE) Some of you may say, well just increase your subwoofer level by 10dB when watching DTS material, but that is not a solution, as doing so gives the correct level of LFE but adds an unwanted 10db to the sub-80hz audio that is being filtered from the other 5 channels by bass management and thus adds a hugely boomy sound too as you would imagine. (I use a THX speaker setup and have to set all speakers to small and x-over at 80hz). I need to be able to alter the .1 LFE channel independently, which is not an option on this amp. Anybody have any suggestions of what course of action to take? Strictly speaking, the product is faulty, as it is advertised as a DTS decoder, but it is not decoding DTS properly. So should I contact Denon and take it up with them? Ideally there is a newer firmware for the A10SE, that includes an adjustable LFE setting, does anybody have a very late A10SE with different firmware? This is really annoying me as I would like to enjoy DTS soundtracks correctly, not a huge request considering the expense of this bit of kit.
