Passively bi-amping

I disagree on the Aleph 5's. 802's are rated at 91 db and I've drivin them with one Aleph no problem. With both amps hooked up I reached 110db and man it was LOUD. I brought home a Ayre power amp home from my dealer. Don't know the model but it was 10 grand and weighed 95 pounds. I hooked it up to the 802's and at 200hz and below the Ayre was superior. Above that the Pass's blew the Ayre away both in sweetness, smothness, and all around sound quality. I took the Ayre back the next day. Yeah I wish my Alephs had more balls, but they are one of the best sounding amps I've ever heard. Not good for your electric bill, however.

I hear active bi-amping is tricky and my personaly opinion is intergating subwoofers is almost impossible to get right.Plus my room is bass heavy. Could use a pair of 16" Tubetraps. I have a small room for such a large speaker and am able to acheive sufficent volume levels with the Aleph's. I don't have a lot of headroom. Turning the 802's any louder than my normal rock n' roll levels does cause bass clipping. Just have to keep an eye on things. I'm running 8ft Transparent speaker cables. Just wish I could have turned those 5's into monoblocks. Nelson Pass said no way. Don't have the scratch to be investing in any more equipment right now. Just be happy with what I have... Thanks for the feedback!

I do have some respect that these a under powered amps (Pass Aleph 5's) for the Nuatalus 802. I have a notch in my Aleph P. When turned all the way to it is plenty loud for this rock and roll animal. Bass is tight, no sign of distortion. However if I turn it up any more my amps run out of gas and the bass begins to clip. So I keep it under the notch and the sound is fantastic. Steely Dan's Aja is mind blowing. So is Gish by the Smashing Pumpkins. BTW I'm an analog enthusiest and also have a Pass Aleph Ono. Will take the Pepsi Challange against any CD player.
