    Hi folks,

    Just ordered the Epos Els3 surround speaker package and have a one year old Denon 1604 amplifier to drive it with. I bought this amp thinking it would be good enough to support the necessary speaker upgrade which has now come to light. I have learned from a lot of reading that this amp is more suited to driving easier loads such as sub/sats like Kef/Genie/Wharfedale 9 hcp etc.

    Is this amp really going to struggle and will the speakers perform so far below their ability that it warrants an immediate upgrade or can I still enjoy the speaker upgrade which I have chosen without having to change the amp straight away? I have heard that too little power can damage speakers just as easily as too much and the last thing I want to do is damage my new speakers.

    If I am kidding myself with this amp matched to these speakers please feel free to tell me as I will look into an upgrade. What reasonably priced amp would you recommend to get more out of these speakers? Would something like the Denon AVR2105 or award winning 1905 suffice. The yamaha 450 or marantz SR4500 are all also in my price range. I would like to stick with denon but am also partial to yamaha amps. Your advise, as always is most appreciated folks, Ronan

    I've bought the Els3 surround package as well - auditioned it with the Denon 3805/2805, and the Yamaha 2500/1500. Finally settled for the Yamaha 2500.

    Hi Ronan,

    Glad to here that you have finally found some speakers.

    I know I was “one of the ones” that made your speaker selection more difficult by commenting on your amp.

    Potentially, your amp and speaker combination may present a few difficulties, but this will only be when you are pushing the amp to at the upper limits of its ability.

    For listening at low to moderate levels it will be fine. So you can use your new amp and speakers together now. I would warn you to become familiar with the combination first, and gradually increase the volume over a period of time (checking that the amp is not over heating or showing any sign of distress) before experimenting further.

    As a general rule you need to double the power output to increase the volume by 3db, and I think your speakers are rated at 86db/W, so you only need 1 watt of power to produce a sound level of 86db at 1 metre. I think your amp should be able to produce a “clean” power output of 25W all channels driven into an 6 ohm load (though I have nothing to support this), so you do have a bit of room to play with.

    Having said that, your speakers would benefit from the better quality amplification. I would be more inclined to live with your current situation and save a little more and get a better/bigger amp. Or look for an second hand amp (but that maybe a little difficult in Budapest – IIRC) in your current price range. Many of the amps mentioned will still have the same issue, but could be addressed by adding an additional power amp using the pre-out sections.

    Thanks for your reply and support. I think I can stretch it to a Denon 2105 in the next couple of months or a yamaha 650. The Denon is available at a fairly decent price now, around £300. The yamaha's are well priced here compared to Denon. Am I being realistic with either of these? I cannot see mself paying £700 for a Denon 2805, my divorce papers would come instantly if my wife ever saw the receipt! Looking forward to your advice as always, Ronan

    Yes, you are being realistic. That is the level you should be looking at.

    Just found a new yamaha RVX750 on sale for £280. Even better amp than the others mentioned above. Read up on it last night. Seems like a fine solution for me. Thanks again guys.
