I don't visit this part of the Forums much so please forgive me if this subject has been covered before. I was setting the levels on my A2 last night using the ULTIMATE PLATINUM DVD. This paticular disc enables you to set levels for all sound formats (DD, DTS, PCM etc) and then compare them against each other. I set the initial levels to 75db on the Dolby Digital setting, including the LFE channel. I then switched the sound format to DTS and checked again. The main, Centre and rears were spot on but the LFE was some 7db lower. I've read some reviews on so called budget amps recently and read that these have the some trouble, some up to -10 db. Luckily for me an all A2 owners, there is a facility to increase/decrease the LFE channel in DD and DTS. My DTS level is now set to +7db and sounds pretty spot on. My main concern is - what do you do if your amp does not have the facility to increase/decrease the individual sound format LFE's? I had a Denon up until recently and am pretty sure this amp didn't have this facility. Anybody else??
