    Yeah, I didn't mean that the amp was faulty, simply that with all those KT150s and 400W at the helm, it should've blown your head off and sounded 'huge' and powerful, with kick-ass dynamics, not "very polite, not particularly dynamic"!

    That's the very LAST thing the Copper amp sounds like, at a quarter of its power.... When listening to the 400W beast, I'd have expected to have seen a reaction like than merely 'meh'....



    Copper amp - what can it dump as a peek power output? Any idea? Bear in mind I have heard it and I agree it is dynamic - but that was with KT88s IIRC?
    Dunno the peek power output. I could find out. You heard it with KT120s. It's now been fitted with KT150s.

    Shouldnt need central heating anyway. Just a small fan to circulate the warm air. Must use a lot of power.

    “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.”

    The output is what ever maximum SPL your speakers will produce, not what the amp has on tap!

    What ever Tannoy specify the Monitor gold 15" to be, However, perceived dynamics is not all about maximum power, as experience has proven time after time! Some amplifiers, no matter how much power they have on tap have no life, or perceived dynamics, at reosnable listening levels, untill they are pushed, and by then are far too loud! With any amp though, it will depend greatly on Amp and speaker compatability.

    They are good amps, Marco, They really are. Just because they don't blow yer mind with dynamics, doesn't mean the way they present themselves isn't a very valid alternative. They will play loud in 4 Ohm pentode mode, and sound bold and architecturally strong at high volume. They do loud in a refined, effortless, somewhat laid back, easy manner. That's no less valid than fucking your head up with proficient current dumping like a Parasound A21. And that really will blow your mind at high volume at a tenth of the cost.

    I liked them more than most people seemed to. I just appreciated their subtle approach, more so as time went on. My wife avidly prefers the 40 year old Accuphase M-60s. So did Jon the Apogee restorer only last weekend. Jerry couldn't be arsed to come round and listen to them.

    They grew on me as time went on.

    Most 211 circuits I hear I have to say sound very similar. They're usually far more dynamic than the Ayon. Bass dynamics and a fleshy, outward, full, dynamic sound, with an extended bottom end seem to be a common trait of the breed, single ended or PP. This is possibly at the expense of a refined top end it would seem. They can be a little brash up there with some speakers. Audio Note Tomei on AN/Es share many attributes of my amps. Even my amps driving AN/Es sound very similar in many ways to the Tomei. Maybe it is the circuit topologies being used rather than the valve. I can't be sure.

    Anyway, enough of this subjectivism. It is total dross really. It is all in my head, and probably isn't in yours. It is a personal journey after all.

    Guess I'll never be a hi-fi reviewer. I'm too aware that the words that I speak are meaningless

    Sure I checked them out. Self testing and protection is very elaborate. Sounds to me like the perfect qualities for today's hifi publications.

    Not quite. I could have bought them for a superb price. I didn't And the owner sold them after just one listen. Aquired taste maybe...

    They are damned expensive new and you are paying serious dosh for the finish and construction quality in general, plus the self-checking stuff must have cost a few bob to develop.

    The protection is elaborate. So elaborate in triode mode they'd shutdown every time I played Natural Mystic at volume - the intro bit that just gets louder and louder has a bass kick drum that Ayon's engineers obviously decided was too much! Superb track that, though, the Apogees just freakin' love it.
