Hi, quick query. I haven't joined the 4K camp just yet, but going to very soon. My question is, only my panny all-in-one for Blu-ray (non-4k), I have to crank up the volume when playing Dolby TrueHD, less so for DD and even lesser for DTS Master. To get any decent sound from TrueHD, the volume is at 55-55 e.g. The Dark Knight Is this the same scenario for 4K blu-rays? I will be using a AV receiver but will also be buying a 4K all-in-one for a smaller room. Never understood why Dolby always had lower sound levels.
