Bi Amping your stereo system
« on: August 02, 2019, 05:39:30 AM »
Is this really beneficial to the sound quality or just a marketing scheme?

Maybe the audio freaks here at weenie can give a definitive answer cause I can't find a straight answer on google.

Running separate circuits and separate speakers for high, mid-range and low range is nothing new. Audio engineers, EE's interested in music reproduction and hobbyists have been doing it for quite sometime. Whether or not we would benefit from doing it for  Country Blues reissues is another matter. Here's a link to a basic explanation:

I've listened to some great music systems over the years, but sometimes I wondered if the person who owned it was listening to the system they sunk big bucks into or to the music it was reproducing. I'm a consumer quality guy, but that is determined by my budget. I still use my AR  turntable and AR 4 speakers I bought around 1970. Maybe if I had more to spend, I'd spend it on a better system:

At this stage in the game, my hearing is another limiting factor. "You can't polish sh*t," as the old saying goes.

Here are links to a couple of tangentially related papers:

Ham stuff, but you get the picture. Speaker wires and other cables can pick up RFI and this in turn can interfere with what we hear.

Live sound setups frequently employ bi-amping. Personally, I have enough trouble managing all the permutations all the way through the signal chain that adding more knobs to twiddle would make matters worse. But for top live sound engineers (i.e. not me) of course it gives you a lot more control. I have so much respect for great live sound engineers.

But on a home system, why not? You can spend hours dialling it in, without getting beer-canned from the crowd and humiliated from the stage! I say "go for it". Hell, get a 2 channel mixer with low-noise and great EQ while you're at it.
