    Hi,
    Can anyone tell me what benefits I would notice if I tri-amped my Kef Ref 203's. Currently they are bi-amped but I would like to bi-amp my 202c as well and I'm thinking of getting another Arcam P7 (I must be mad!)

    Regards
    John

    No doubt you will get a string of posts opposing my view but in your position (which I was a few years ago) I would sell you're existing amps and buy a single amp of better quality. The only time to consider multiple amps is if you are using active crossovers.

    Or do nothing. What do you think is lacking on the centre channel?

    I'm inclined to think with Gary on this one- many fantastic rigs that I've heard in the past were single wired with no means of increasing cable runs/amp numbers. I feel that the improvement may well be disproportionate to expense.

    I would tend to think that going from bi to tri isnt going to fain you that much for passive crossovers.

    I used to use a Rotel 993 on each kef 203 and the 202c, tri-amping each speaker at 600w to each, i have since "down-graded" to a mere 250w mono-block per speaker (Tag 250mr's) and a single 1.3m(ish) run of Nordost SPM cable.
    Different class altogether.

    But........ the Arcam is a good enough amp to bring about a gain when triamping is it not?

    Cost vrs gain is the ultimate question though.

    Yeah..... there has to be a point there single wiring with a better amp wont be a better idea, simple result of the law of diminishing returns. A £2k 2 channel amp is pretty high end even for the well off, if you buy a 6k amp, it likely is only slightly better. I would think that 3 of the 2k amps would be a better solution

    Well, since we're spending his money and he's bought another amp, let's make use of it and buy another set of KEFs to triamp in 7.1.:laugh:

    So let me get this right, to use analogy you are saying that it would be better to add a second Rotel power amp to bi-amp a stereo pair than to use a Musical Fidelty 2 channel power amp of the same or there abouts cost? (of the two Rotels)
    I seriuosly doubt that this is sensible spending if you are after an "up-grade" than simply more headroom at the same qualitly.

    Apologies if i have misunderstood.

    Regards

    I would agree with you steve, the MF is the way to go most likely. But if you were talking about buying another 250R to biamp or selling up to get a lower Krell.... id go 250R every time

    Hmm, at that kind of price level I think I'd get a home demo every time......

    oh yeah, without doubt.....my point simply is that there will become a point where, despite price difference, the performance difference will be so small that the increase in performance due to the amp will be lost in comparison to the potential benefits associated with properly biamping, if you follow

    a) I disagree.

    b) It isn't just a question of the amplification anyway. If you're going to spend £4000 on upgrades then you could not only afford better amplification, you could get better speakers as well. That's going to make far more of a difference to sound quality than multiple amplifiers.
