Bi-amp myth true false rti a9

[Pinktulip7]

Finally I have done Bi-Amping RTi A9 with Carver M1.5T 350 WPC (Powering Low Pass) and Carver M 4.0T 375 WPC (Powering High Pass)...now after experimenting for couple of hours I realized that very little or no sound improvement over my previous setup which was RTi A9 Bi-Wired Powered by Carver M1.5T :(:(:(

That is fairly common. Similar designed amps on highs and lows with the same type of speaker cables, and IC's yield less than impressive results.

Interesting.I have bi wired and amped for many years.Bi amping makes the bigger audio difference.But is it for the better? Hearing more controlled bass and cleaner highs at the expense of musicality?Hmmm my jury is still out on that one.Something in the line of CD vs. analogue.From a technical perspective it has it's merits but I'm still not convinced ;)

SeaFart should be taken with a grain of salt. Anytime Sea nothing reads a post by members with more than... Posts he goes against the grain.

Passive bi-amping(using integral passive xover) will gain you a few extra DB of headroom that may be advantagous if both amps are lower power units.

IMO the real sonic gains come with active biamping were the passive xover is bypassed completely , instead an active line level xover is used.

The only way to KNOW is to try the combination you are considering. Did you try biamping both ways? Bass-bass and treble-treble vs bass-treble and bass-treble? The two ways are called horizontal and vertical bi-amping respectively.

Something to be aware of when passive biamping is the input sensitivity( or gain) of the amps.It should be the same on both amps or you will alter the balance between the woofer and tweeter.

+1 on that, and also to Ben's post above...it is recommended by many that you experiment with different kinds of cable and even different gauges of those cables in bi-amping. I've haven't done this enough to suggest what to use. The guys above probably know a lot more....

I had very good results bi-amping my SRS's before I bought my Cary. I noticed an immediate improvement in space and clarity of the highs with slightly cleaner bass. The Parasound combo of a HCA-2200 and 1000 was insanely dynamic. I bet a Halo A21 and 23 would deliver very similar results with way better highs. That's where my Cary really shines. Smooth but detailed on the top-end but still enough juice to rock. I want to pick up another CAD-200 or a Cinema 5 one day.

Mad max wouldnt you think that you would have to have 2 of the same amps to hear if this works correctly.

I am very intrigued to find out what happens with OP trials. I am looking to experiment with my 9s and was hoping bi-amping is the answer.

Sounds to me that you once again have your head stuck someplace rather stinky... More controlled bass response and cleaner highs IS musicality and is a benefit gained, not lost as you presume. Go back to playing that kazoo and recorder you and your imaginary friend call an orchestra and leave the audio discussions to those that appreciate true sound...

No I haven't try with same Amp but will give it a try and thx for all response....

if your amps are able to be bridged you may try that as well. Then by-wire the speakers.
In my research i found the adcom 555se bridged is 600watts/chann, then i would bi wire them. One amp for each speaker of course. That would rock I think. I hope to try and test it out soon.

Don't dismiss bi-amping as a myth.Your results with bi-amping will vary depending on the amps, speakers and associated gear. You are doing the right thing by experimenting.

I tried it a few years ago and had mixed results. You can read about it here: SDA SRS 1.2TL Bi-Amp Adventure (http://www.polkaudio.com/forums/showthread.php?t=10191).
