bosso - I agree that full range can be sent through all six channels but my limited DVD-A collection has not shown that in most cases. I also 'think' that most of us are not listening to everything at reference levels at all times so feeding those not so "full range" speakers a frequency they can't produce doesn't hurt anything as long some discretion is used with the black knob.
Just a difference in the definition of a "full range speaker". I usually consider a speaker full range if it can produce healthy bass below 40Hz. Maybe if I explain the front sub setup it would help. My NHT subs need to be handled by a controller. Each sub has just an on/off and an RCA feeding the amp. The controller allows for line level as well as LFE inputs.(also speaker level) You can high pass through the controller but I don't, that is handled somewhere else. Anyway the controller allows you to adjust main volume(line level inputs) and LFE gain independently for mixing in the desired amount of LFE. Low pass for each is handled seperately. So I take the front L/R outputs from the 950 split them one going to the sub controller and the other going to seperate sub amps driving the lower sections of the main speakers. I listen to most things with front speakers set to large.The full range signal used by both the mains and the sub with the sub low passed at around 40Hz allowing it to "augment" the deepest bass as the mains start to drop off in repsonse. The rears each pass through their own sub which is high passed at 80Hz making each of them acting as "full range". The rears are being fed with speaker level inputs so if I were to activate the 950's BM I would essentially remove all bass from the rears. Each speaker is in close relation to it's sub so they act as an entire unit making placement easier to me.
As for specific stereo bass on any songs I will have to go through and check but again I 'think' there is stereo bass in most recordings, maybe not a lot of seperation but can notice it quite often. It's subtle but it's there.
I also consider myself a novice and am thankful for this forum. This forum IS the reason I bought the 950/770. I was not looking for a way to point out the 950 shortcomings but following the original posted question of the correct way to hook up a 47a and I think the BM issue needs addressed for this. I hope tekdredger buys the 950 and trys it out for himself. I think given everything he will be very pleased.
