    I'm saving up for an upgrade. I was wondering where would be the best place to spend the money, amp or speakers? I am currently running a Pioneer LX 83 with Q500 fronts and Q200C centre. My original thinking was to upgrade the speakers to the Kef R500's. Any thoughts?

    The Kef R200 centre is a fantastic speaker. I'm about to get one, paired with LS50's. It sounded great with the Standmount R300's as well.

    If budget is limited it might be worth thinking about those options. I imagine the R500 sounds great though.

    The Q500's are great (I've had a pair) but they are the weakest link in your system. +1 for the KEF R Series.

    I would at £799 it's a bargain and depending on your room can do wonders.

    Very tempted. Have to have a ponder. I'd have to sell on my LX83 though.

    The R500's are fabulous speakers as is the R200c.

    I can also confirm they match very well with Anthem MRX300 and 510.

    You have a similar setup to what i would eventually have if I bought the Anthem mrx 500. Is there much of a difference between the 500 and 510, apart from the way it looks?

    The MRX500 probably also has better amplification than the LX83 asn Anthems have high currents. Useful when the impedences of those speakers drop!

    Th2 x10 series have a completely new DSP for both the ARC and bass management (which is part of AC i suppose). The overall tweaking is much easier. The filter density of the ARC is close to the D2V, which is substantially higher than the x00. What it means is that the resolution of the correction is much finer and accurate. The preamp stage is also said to be better.

    Which is not to say the x00 were bad. Its just that the x10s are so much better.

    Case in point, many owners of the x00 recommend dropping the max EQ frequency to 500Hz from a top limit of 5khz to increase the amount of corretion over a limited frequency range. With the x10, that certainly isn't a problem, but what I found was going up to 5khz helps multichanne content while dropping to 500Hz is great for 2.0 sources. So you have choices, which is great.

    If you're not running 7 speakers, why not consider the 310?

    Speakers are important, but good speakers still need a good signal. Anthems are relatively neutral without being sedate like Arcam. they are easy to match.

    I'd like to bi-amp the front left and right speakers. I'll be running 5.1 though. I'm tempted to save up for the 510 then save for Kef R speakers. Unless the sound from my Q's is good. Selling my lx83 and hopefully negotiating a discount I could get the 510 now.

    Depends on how far you want to go. Biamping is not so necessary, and probably unnecessary if you have ample amplification. If you're thinking of a single box solution and future Kef Rs, a 710 is more suitable.

    Some dealers offer tradeins.

    So the Q's would be more suited to the 510?

    ok Garry, you sound like you have ambition for your system. This is not a question of one component, but about moving to the next level.

    This upgrade game is more intricate than you think. Don't know if you play RPG games; but its a bit like building your character. Do you maximize one skill set or do you move to the next level of skills?

    A lot will depend on your budget, WAF, physical space and personal preferences.

    Its all about component matching and getting the best out of what you have. All decent speakers will benefit from powerful amplification. But you can get more with expensive speakers. Or look at it another way, you get poor returns from that extra expenditure.

    you have to strike a balance between being able to enjoy what you have, and also get best value.

    IMHO, if you are thinking of getting the Kef Rs, you should definitely think about getting a monstrous power amp. If the latter is not an option, you have to seriously start thinking about the 710. The 510 will struggle to drive a floorstander based setup properly. It won't kill the AVR or the speakers, but you just wouldn't get a nice sound.

    You should also change your sub. Having gone thrugh a simliar road and exploring the capabilities of the ARC, here is one potential upgrade path.

    Get the 510 for now and biamp your Qs.

    After that, get a really good sub. Not a loud sub, but good one. Why? movies are about immersion. a good sub will support the soundstage at low volume, low requencies. It lends attack and weight to the higher frequencies like a drum beat, piano key and bowing of strings. Its amazing how important low frequencies are. Your soundstage will be lifted forward. It will also sound louder because it has more impact. No, it won't shatter windows. Quality, not quantity. As always, if you're nearby, always happy to demo this in my little flat and i can show you what I mean.

    With a good sub, you can crossover your speakers at 80-90Hz. This helps divert energy consuming lower frequencies away to the sub which has its own power amp, thereby reducing the strain on your AVR. Again, the Anthem does it so well, particularly with the ARC, that this will happen seamlessly and easily.

    Then, upgrade the speakers. Because you have the sub which is like having some power amp support, you don't have to worry so much about inadequate amplification. A good sub will also be tonally matched to good speakers.

    Finally, add a power amp and your whole system will sing. No, not that it will shake the house down. the paradox is, a power amp actually makes listening at low volumes possible.

    If it helps...I have just replaced my lx83 with the Arcam avr450 driving my R700's/600. What a difference! Arcam/KEF combo is sublime, especially for music. Loads more power too.

    You should upgrade the speakers first as it would make a more audible difference seeing that you already have a very capable receiver. Then you could try and find the best way to get the most out of them.

    Very tempted by the MRX500 though. While they are available, just wondering will they drop in price again.
