I don’t think so. Simplistically each amp is still amplifying the full range-signal and then half that amplified signal is being “thrown away“ in the crossover. So the total power available is roughly unchangedwouldnt i have double the power available to each speaker?
Greetings ASR Family,
I’m new to posting here and have a couple of technical questions that I think I will be able to get straight forward answers from.
I recently came across my “Endgame” speakers at a price I couldn’t say no to, the Kef Reference 5, side note they are amazing.
I’m also a sucker for vintage Yamaha power amps. That’s all I have really known other then AVRS. Maybe it’s the bouncing red lights. The simple geometry, but probably mostly budget constraints. As I picked it up for a Hundred bucks….
I have everything hooked up and it sounds awesome to me. I stream Tidal connect to a Bluesound node 2i, SE out to the Yamaha C-60 pre amp, from there SE out to matching Yamaha M-60 Power amp. And from there using modest speaker wire to the Reference 5. All is good and I really couldn’t ask for more.
As a audio junkie on a budget…. Scrounging fb market etc., I came across another Yamaha M-60 power amp for you guessed it, a hundred bucks and picked it up. Seems to work great and preformed the basic maintenance checks from the service manual. Setting the pots to 10mv at idol.
Now comes the real question…. And maybe I’m nuts “this is where you guys come in”
I would like to hook up both Stereo “non bridgeable” power amps, one to each speaker.
My thought was From Each channel of the pre amp, Y-split to both cannels of the power amp. Remove the link of the KEFS and run “left channel” to the highs and “right channel” to the lows and do the same for the other speaker, effectively Bi-amping.
Is this a great idea, a bad idea, a pointless idea and why,
I have attached the specs of the power amp, the pre amp and the impedance curve of the ref 5.
Thank you all so much for any input.
No you never need those cables.When you passive bi-amp, do you need fwo more super-audiophile grade speaker cables? Because those things are more expensive than good amps
Sounds alright. BUT I wouldn't be sure that the "sound profile" is the same between the two amplifiers. Your way may have more pronounced bass on one channel and less on the other because of difference in "wear and tear" and minute differences in bias, electrolytical capacity ESR etc.. I would do it like you and I would make sure there is no difference in sound characteristic by doing a REW measurement.Greetings ASR Family,

Measurable? I must have missed that part of the article. But I did find this:Everything You Need to Know About Bi-Amping
To Bi Or Not To Bi – Bi-amping is considered one of the "ultimate aspects" of sophisticated high fidelity. In this essay, you'll read what it is exactly, how it works and what the benefits are.stereo-magazine.com
Interesting read - there is some measurable science behind it.
I have done blind test bi amping my R3 and difference was staggering - using AVR average amps was able to get sound much closer to 2k integrated stereo amps. Obviously this might differ depending on speaker and class of amp used - maybe better the components less of a difference. Who knows - only way is to do it and blind test it.
Also there is a lot of talk 100w vs 2x100w being negligible - well from power perspective sure not much change but mid high by having separate power will not be affected by LF trying to draw all of it for instance which might happen with some dynamic peaks with some music.
no.wouldnt i have double the power available to each speaker?
