Amplifier power
If all (properly designed) amps sound the same, how do I decide which
amp to buy? Is it just a case of choosing one with sufficient power output and how do I determine this? |

It would depend on various factors: What kind of music you like. How large your listening room is. What speakers you will be using. etc. You would have to also define what - for you - was meant by "properly designed". e,g. some amplifiers have a high output impedance and/or a deliberately tailored response. Are you likely to wish the effects these might cause? Plus: The snag with "properly designed" that all real designs will have performance limitations, etc. Within those, two amps might deliver results you find indistinguishable. But with some speakers, or under some conditions, one might work fine whilst the other struggles. Plus: Some 'amps' may have an RIAA input (for LP). Others not. Would you need this or not? Would you require MC to be catered for, or not? So you would need to be more forthcoming about what you require the amp to do, and the circumstances in which it would have to perform. Giving us this would also help us to tell if you do wish to choose an amp... or just to start an argument. :-) Slainte, Jim -- Change 'noise' to 'jcgl' if you wish to email me.

... If all (properly designed) amps sound the same, how do I decide which amp to buy? Is it just a case of choosing one with sufficient power output and how do I determine this? It largely depends on the efficiency of your loudspeakers, the type of music to which you listen and (perhaps to a lesser extent) how loud you like to listen to it and the size of your listening room . If you had very efficient speakers - like Lowther PM6 units - with a sensitivity of 92dB/W or thereabouts you could probably get away with 10Wper channel. If they were/are more like the efficiency of a few modern units at, say, 82dB/W then by that process you would need 100W/channel to achieve the same sound level - 10dB being a factor of 10 times in terms of power. Given that many speakers are around 86-88dB/W then an amp of the order of something like 25-40W per channel is about right. You should have no difficulty finding an amp within that power in this range - look at those by NAD, Cambridge, Marantz, Denon, Harmon-Kardon, Sony, and Yamaha as examples, with www.richersounds.co.uk being a good starting web site. However do not be afraid to buy an amp of greater power - which actually you may find easier to do. You are unlikely to damage your speakers with too much power - you will hear the effects (usually 'cracking' on music peaks) long before you do them any damage - but it is very easy to blow them (specifically the tweeters) by having an underpowered amp and turning the wick up too much. (If you want an explanation of how this can happen just ask.) Above all, if you listen to music that requires details - such as classical or jazz, as against heavy metal or rock - then do try to at least listen to the amp in the shop before you buy it. Although they are all designed to achieve the same sonic end they do sound different. -- Woody harrogate three at ntlworld dot com |

Focal JMLab Chorus 714V Power handling 130W max Sensitivity 91dB Above all, if you listen to music that requires details - such as classical or jazz, I do as against heavy metal or rock - then do try to at least listen to the amp in the shop before you buy it. Although they are all designed to achieve the same sonic end they do sound different. But do they? And even if they do, the trouble with listening in shops is that the listening room is very different from where I will be using the amplifier. Phileas |

YOU SHOULD CROSS-POST SUCH QUESTIONS TO RELATED GROUPS SO *EVERYONE* CAN SEE THE THREAD AND THE ANSWERS AND YOU DON'T GET WILDLY CONTRARY ANSWERS. You just waste everyone's time with multi-posting and it really ****es ME off for one. Graham But SHOUTING and multiple posts which carry no contribution from oneself are perfectly OK. -- Graham. %Profound_observation% |
