Lossy encodes are normally at a higher dB than lossless to make up for the "lossy" signals. Could it be that what you are experiencing in the LFE (punch) is due to higher dB? Comparing lossless to lossy you usually have to turn up the volume of the lossless formats. Added to that the LFE channel on lossy signals are normally jacked up during encoding. That is why most of the AVRs normally have controls for each channel especially for LFE.

Another thing to remember that not all lossless encodings are equal, there are some DTS Master Audio, Dolby TrueHD that are not recorded at high bitrates. For those encodes, the difference between lossy and lossless is less. Some lossy encodes are 740Kbs vs some lossless only at 1.3-1.5Mbps. And the reverse is also true, some lossy encodes are top notch, and the differences might be closer...With higher bitrates there is more information to relay to the listener. There is more details if you are listening carefully and the sound space and imaging is more accurate.

My 2cents worth...

T2 Lossy signal is supposed to be very good (DTS-ES I believe but I might be wrong). The DTS Master Audio was a very low bitrate encode. There are some posts in AVS forums showing the bit rate comparisons between the lossy T2 (HD-DVD/Blu Ray US version) vs the lossless UK encode (DTS Master Audio) and they are only slightly higher for them. This might not

The 2nd portion of the report is saying that the if you extract the lossy core from a lossless track, in this case DTS Core (1.5Mbps) vs DTS Master Audio lossless. DTS Core is higher bit rate than the DTS you get from DVD (normally not more than 784Kbps). In this case, depending on the movie, maybe the difference was negligble.

Anyway, the important thing is if you do not hear the difference enjoy your BD/DVD the way you want to enjoy it. If lossless does not do anything for you, then so be it.

Different strokes for different people.
