    Considering the Denon AVRxx03, Marantz SRx300, Yamaha RVXxx30RDS, maybe Sony. My hi-fi cabinet upper shelves have a max depth of approx 17cm, and the Denon amps are 171mm high. The Marantz at 164mm would just squeeze in with approx 6mm to spare!!!

    Or I put it on the bottom shelf (you know, where the ancient cave dwellers used to store things that were called "LPs") and knock a big hole in the back of the cabinet (thin wood back fortunately!).

    They are not only tall but also deep. My Sony 555ES is deep already, but then add on the extra depth of all the cables out back and the controls out front and it is actually deeper than it is wide.

    I'm having to build my own rack.

    Cheers

    They're big because there's so much that has to fit into them and stay cool.

    I'd put it on the LP shelf in your case, it's will be well vetilated here at least.

    You get what you pay for etc. The small Pioneers aren't a patch on the 'proper' sized components, you can't fit all the goodness in.:D

    Alot of newer AV amps are 7 channels, so they have 7 channels of amplifcation, with heatsinks on each channel.

    You can't expect to buy a Krell the size of a Sony DAV unit (with the same performance)

    My Denon A1SE is 434mm wide x 216mm high by 486mm deep. It weighs almost 30kg.

    I really hurt myself trying to put it on my rack on my own!

    and this is exactly the reason why we should all sell up and buy separates! Which i reckon are much better into the bargain! :D

    Yeah, but if by separates you mean a DSP processor, separate power amps (between 3 and 7 of those I guess), the cost will reach £10,000 and the space required would also be enormous, not to mention power sockets and etc. etc. !!!

    Hell no it doesnt! Admittedly i spend all my money on it, but im only a student and can manage! There is a second hand rotel 966 in the classifieds at £250 and matching power amps are not hard to come across for £500, that equals a cracking separates set up for very little money! :D

    Hmmmmm ... does using a multi-channel power amplifier count?!!! Sure, it's more separate than an AV amplifier, but not as separate as 7 independent matched monobloc power amplifiers ...

    Also, with AV processing, second hand kit is likely to be using older generation of chips and technology (unless it's "recent" second hand) ...

    It's still not £10,000 though.

    Rotel RSP1066 - £900
    Rotel RMB1075 - £850
    Rotel RB1070 - £500

    Not DSP and mono-blocks admittedly ... but close with 7 channels of amp, separate from the processor. The power amps offten appear hear and at dealers, etc second hand as well.

    Are YOU aware of the necessity to read words in their context? So like a 17cm shelf "depth" ... guess which way I meant?

    since i have neither your hifi rack, nor a Denon amp, i have no idea which measurement is 17cm.

    Hey guys ... lets cool it a little ... I think we can all work out that 17cm is going to be the distance between shelves not the front to back depth of the shelves!!

    When I was a student £750 had to last me a term, books, food and accomodation. Im only a fully employed solution architect and I still cant afford to spend £750 on just the amp!!!! How on earth can you afford it?

    I own a Pioneer ax10, which is quite big, but it is actually smaller than the 200-disc cd-player it is resting on. I have them standing on my bureau, which is next to my hifi-setup. Looks great! :cool:

    As a couple of people have already said,if you think AV integrated amps are big,wait until you try separates....each of my Krells is at least as large as the Pioneer VSA-X10,but considerably heavier and they run somewhat hotter also.

    Seriously though,good AV amps are large due to the physical size of the components inside(esp.the power transformer(s) and power supply)plus heatsinking to ensure adequately cool running of the output stages.

    Not only are they big in size but also incredibly heavy. Some around the 20KG mark. I only have a smaller yamaha but i had to consider carefully which shelf i put it on on my target stand. Because of the ventilation they require it can be a real pain to find the right place to site it! :)

    Cant resist it.....have to say again that you need to try hefting some proper power amps around....try a decent set of Levinsons or Krells for sheer mass at around 50kgs apiece in some instances....makes even the heaviest AV amps look appetizing when it comes to shifting stuff around(like I've just had to do as my wife thought the telly was too close!)

    That's still a fair whack. You can buy a second hand A1SE for less than the RSP1066, add a stereo power amp for the fronts and you can then use the unused channels in the DENON to power a second room if you feel that they are being wasted.

    Then all you have to do is spend 400 on a rack strong enough to hold it.
    :laugh:
