    One of the things I cannot find out about my power amp is whether it is class a or a.n.other. All I know is that it is EL34 push pull with an output of up to 40 Watts per channel in ultralinear or 20 Watts in triode. I was though listening yesterday to Museum Of Consciousness by Shpongle in ultralinear and it sounded bloody sublime (with the sub). As has already been stated here, my guess is that the modus operandi is largely dictated by the music. Bloody lovely sound, well impressed.

    It is most likely class A for the first couple watts 1 to 1.5 then as the amp is pushed moves to class A/B. I am not a fan of pure class A amps that do high power.

    Its most likely to be class AB1.

    So, apart from headroom, would anything be gained by moving to Temple Audio monoblocks with separate PSU's over a Class AB1 valve amp..? How do these amps sound when compared to EL34 valves...?

    Sorry Shaun, was this question aimed at me ?
    If so, I can't really offer any useful opinion either way, again, sorry.

    Anthony, sorry for the confusion. The question was aimed at anyone who can help really as the Temple Audio monoblocks are apparently Class D and so have no crossover distortion..? I just wondered how this may compare to a Class AB valve amplifier...? Also, whilst talking about amplifier Class types, I know that my head is full of confusion on the subject. Class A, no crossover distortion, surely that is applicable to single ended...? If you are using one amplifying device per channel then there is no crossover between the positive and negative cycle..? Hence no crossover distortion...? So how the hell does single ended and Class A differ..? I understand that a Class A device is permanently 'switched on' or drawing from the mains supply...? It does my 'ead in

    Hi Shaun,
    Understood. As for class A, in theory; if the amplifier in question is true class A then as you quite rightly say,,,it shouldnt matter whether it was Single ended, or Push-pull, it will have no cross-over distortion, because each valve will be conducting 100% of the time, however; most conventional class A push-pull power amplifiers will often draw a little more current when pushed to their maximum power output.
    Hope this helps.

    So I take it that crossover distortion is caused by the devices switching between the positive and negative cycles..? So from that, if the amp is single ended there will be no switching and hence no crossover distortion due to there being only one device per channel..? So class A and AB can be single ended..? However only Class A is permanently 'switched on' and amplifying..? Still does my 'ead in

    Sussed out Class D yet Shaun?
    It is impossible for anything digital to sound analogue, because it isn't analogue!
