    due to budget restrain i had to go with the wharfedale diamond 9 series instead of a Quad L series sorround system since i will be using it in a 5+1 configuration i will be bi-amping the front speakers with my Marantz sr 7500 does anybody know or has the ratings of the marantz sr 7500 when bi-amped for the front i know that it will not mean 210 watts (105wx2) but i have no idea on how much power i will get from them

    Best regards
    Keirm

    Since we are on the topic:

    How did you bi-amp the SR7500? Normal front outputs to the bass-port and C-speaker (surr-back) to the tweeter or am i not making sence here?

    Greetz,

    Menel.

    Should not matter, as both amps are identical.

    Though I would probably route the MAIN/FRONT to HF and SURBACK to LF.

    I havent done it yet i will have a knowledgable person do it for me or just ask the fellas in here since they seem to know at least as much as the dealers if not more and most probably more :clap:

    but the answer 105 doesnt sound right so whats the use of bi-amping then ??????

    The advantage of bi-amping is having a dedicated amp driving the individual drivers of the speaker.

    That's a shame, I think you should have spent maybe a bit more for the speakers and take the Quad and less for the amp.

    well there was a serious price difference the wharfedale combination of

    1 pair of 9.6
    1 pair of 9.1
    center 9.cs
    and sw 150
    came to exctly 1000 usd which is aound 550 gbp

    and the Quads 12L's +11l's +the center +and the sub was about GBP 1450 i know there is a serious difference of quality but i figured i got a pretty good deal on the wharfedales and when i would want to upgrade and have the budget for it i could sell them at pretty much the price i bought. The future update may be either the quads or the Kef's with the Q7 in front

    So unfortunatly budget was a big issue

    Hi Jazz,

    Was it "bridging" you were thinking about.

    Some power amps are able to be bridged. If this facility is available on the amp as a "basic" guideline, an amp that delivers 2 X #Watts will deliver 1 X (2.5) #Watts in bridged mode.

    i am not so sure what bridging is actually but i will check it out but since in the bi-amping mode i was told i needed 2 pairs for the front i guess that wasnt what i meant.

    But it might just be a possibility if that helps but the question of the marantz beeing bridgeable is something i have to ask it sound like this question is for Kazzman who is the marantz sr 7500 expert in here :) (among others)

    no problem endora i appreciate every feedback and advice i get here since i know that nobody is trying to sell anything like the dealers are.

    As i said the differene of price is much smaller in the UK its not that its more expensive i simply get 25% off of the uk prices in Turkey for the Quads but i believe i got the wharfedales even cheaper then half the price in UK (well since the 9.6's are not available yet i cant comment but that seems to be pretty much it.

    Unfortunatly at this level i had to go for the price/performance issue if price was a lesser issue i might even have gone over the quads and the Kef's.

    but as you know lifes a bitch and money is hard to earn :(
    but waiting for the lottery :)))))

    No, the marantz cannot be bridged. And if they could, I would rather bi-amp in your situation.


    Enjoy your new purchase.

    Your power output would theoretically be 105 x 2 per channel for your fronts as this is what you are feeding into each driver from each amp. You might just get this figure in two channel mode but with all 5 channels (actually outputting 7) driven, I assume you would get slightly less due to power supply limitations. Hope this helps
