    So true and such a bloody disgrace. I guess it keeps the shareholders happy though.

    I would say yes if it is a Class A amp but what do I know ? My knowledge of electronics is naff.

    i dont think your usage at 10hrs a week at just over an amp is going to break the bank, and some ss amps may be same or higher.

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy.”

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    There's nothing remarkable about it. All one has to do is hit the right keys at the right time and the instrument plays itself. -- Johann Sebastian Bach.

    Sugden a21a draws 70w idle or at full output apparently

    Primaluna is 300w

    Elicit r is 37w idle, 270w at max output

    Yes unless the SS amp is Class A.
    I love Hendrix for so many reasons. He was so much more than just a blues guitarist - he played damn well any kind of guitar he wanted. In fact I'm not sure if he even played the guitar - he played music. - Stevie Ray Vaughan

    You need to calculate what your energy usage will actually be. The energy companies are trying to rip us all off by inflating the estimated cost of usage in order for them to make a stash to help them through any bad times.

    We had a similar crazy price but fortunately my Wife, who pays the bills, is on the ball and worked out a more accurate estimate based on actual energy used over the past two years and the figure was less than half the energy companies were asking for. When challenged on this, they just caved in.

    Agreed - Class A amplifiers draw a constant current, and hence power. Furthermore they have a maximumum theoretical efficiency of 50%; and what isn't used to drive the speaker is wasted as heat. (So turn off the radiators in your listening room. )

    I used to use Mark Levinson ML-2 monoblock amplifiers. 25W into 8 Ohm, doubling in power for every halving of load impedance. They have an efficiency of 25%, hence when idling the pair of them pour out 200W as heat.

    my listening room is always nice and toasty 15 minutes after turning the Primaluna on

    If anyone is interested, I measured a Quad 303 power amplifier and it took around 10 Watts at zero output.
