    Hi,

    In the quest for more :devil: I am interested in getting into bi-amping. I havetn got enough room for 3 mono blocks which I think is the simple answer to this. What other ways are there? Amps to use ? Prices? Other accessories?

    Thanks in advance.:clap:

    Well, all the Exposure power amps (which I concede aren't being given away either) can be switched over to Mono, as can the NAD C272 power amps which are also face bendingly powerful- you could (over time) by three to run as monoblocks :devil:. I believe that Naim also do a three channel power amp but I find their model numbers bewildering so can't tell you which one it is.

    Most Rotel power amps can be bridged to mono or you can use two stereo amps to biamp two speakers. I'm very happy with the performance my Musical Fidelity stereo/monoblock biamping configuration works. You get much better seperation and detail.

    Depending on budgets,you have a vast range to choose from,varying from NAD etc as mentioned,at the lower end,up to multichannel Krell and Bryston offerings(as well as many others)at the high end.

    In terms of value,the Rotels take a lot of beating in all of their models,and the sound quality isn't bad either.

    You can certainly gain a lot from biamping,rather than running an AV amp/receiver at or near it's limits,never mind the obvious sound quality gains.

    I think I know the answer here but could I use any (decent) stereo amp from the pre-outs on the yammy to bi-amp the front L/R speakers?

    Thanks for all the help so far.:)

    No, not really as the AV amps will have a sound of their own (and possibly a different gain (volume)), as will those of the HiFi amp and therefore the sound is unlikely to gell together.
    On my previous setup I had an Arcam Alpha 8R & 8P setup biamping the front L&R which made a huge difference to the sound quality IMO. The receivers amps fro L&R were then unused. I could have then bridged another 8P to biamp the centre, but upgraded before getting around to this.

    Hope this has cleared it up a little.

    3 x 180W @4ohm, with power and scale like you wouldn't believe.

    Not well known, but beautiful amps and just amazing sound.

    Bi-amping is different from running mono-blocks. Bi-amping is using two stereo power amps to feed woofers and tweeters seperately, but using the same pre amp. A bit difficult to do with three speakers. So you would need a six pack of mono-blocks to achieve bi-amping.

    IMO if your using the set up purely for h/c, have a listen to your front pair of speakers in 5.1 mode, if they are set to small theres not a lot of information coming from them. Take a listen to the centre speaker, virtually everything comes out of that, so its probably the candidate for better amplification. The other area of concern is the low frequencies, many systems use a sub woofer
    and there are definite gains to be had in this area.

    If on the other hand the system is used for music, then bi-amping makes more sense for the front stereo pair, however what happens with surround music is a bit of a mystery. Ultimately the greatest improvement is to run seperate systems for stereo and h/c.

    I have just laid my grubby mits on a nice Rotel RC850 pre amp and a RB850 power amp. Im just using them to show my Yammy up in stereo at the moment :smashin: :D
    My next quest will to set them up to bi amp my fronts. Is this the way to do it:-

    1. connect preouts of yammy front l/r to inputs of rb850 power amp.
    2. connect speaker cable to yammaha speaker set a.
    3. connect speaker cable to rotel speaker set for each speaker.
    4. Set yamaha to play out of a+b with rb850 on and hey presto bi amped speakers.

    Is this right?
    Thx

    I would recommend using a 6 channel power amp to bi-amp your front three speakers. This will give youa nice even balance acrooss the front and leave plenty of power inside the Yamaha to power the rears.

    The perfect idea would be to do that. Unfortunatly my finances wont stand up to that :( Maybe in time a nice rotel/parasound etc will come along when I have more free cash:devil:

    Is my setup idea correct please??

    Thx

    This method may well work, but it may also sound uneven!

    The thing is that the Yamaha & Rotel amps will almost certainly sound very different from each other.
    Also you may find that the gain of the 2 amps will be different making it impossible to balance the tweeters to the woofers.

    Other than the above AFAIK you will not do any damage to the equipment if connected as you suggested. I would therefore say that you should give it a go and see if it works for you.

    Bi amp using a stereo power amp per speaker?

    So just get three matching stereo amps to bi-amp the front three.

    That was my original plan but space and WAF wont let me. I am looking at geting a second hand ROTEL RB 956AX 6 CHANNEL POWER AMP to bi amp all the front 3 speakers.

    Thaks for all the info all :smashin:
