Valve power - feel the force!

[Marco]

In an attempt to do that in a push pull design the crossover distortion would be enormous >10% and clipping would be absolutely inevitable, but some do regard this as "involving musicality" and even get to like the sound.

Yet more unrepresentative bullshit, JC - certainly in terms of my valve amp in the context of my system.

I think you should refrain from making any more ill-informed comments about components (and a complete system) you haven't heard and know nothing about, and therefore making yourself look even more idiotic until you come and listen, because believe me when you've heard my system all this nonsense is going to come back and haunt you in a major way, and I will not let you live it down. In fact I will take great pleasure in ripping the piss out you here in public in the most cruel and vindictive way possible... You've asked for it with writing all this nonsense, so trust me you will be having a very 'bad day at the office' very soon

Marco has already set fire to his amplifier once

How much longer do you feel it's necessary to mention that? You're being completely pathetic. There was no "fire". A capacitor went pop - that's all, purely because I removed the step-down transformer and connected the amp straight into a 245V mains supply, which is was not designed to work with - my fault, not the amplifier's! It worked faultlessly up until then, as it has done since coming back from repair and modification at Anthony's.

I'm going to make it easy for you, JC. To save you from further future embarrassment, if I see you making any more ill-informed comments regarding my valve amps, or my system, they will be instantly deleted without further notice. Furthermore, I would like to see more from you here other than simply having a pop at 'cable believers' and people who use valve amps because that's all there seems to be so far. Sort it out, and quickly, or your next 'holiday' will be a permanent one.

The limiting factor with most valves is the anode dissipation of heat, which is mainly controlled by the bias setting, not the output power.

In class A, KT88's might provide 10w out, in AB 30w, in class C 60w, in class D 100w.

It is therefore misleading to talk in terms of output power and anyway 60w is only 3db louder than 30w (v small difference)

To exceed double the volume (spl) you'd probably need to go from 30w to 300w.

In an attempt to do that in a push pull design the crossover distortion would be enormous >10% and clipping would be absolutely inevitable, but some do regard this as "involving musicality" and even get to like the sound.

Marco has already set fire to his amplifier once I rather think this "mythical" 100w from a pair of 88's in ab push pull will provide an even bigger bang eventually.

jc,
what is your point, you can go on spitting out quotes and figures, and i can go on answering you with other figures and quotes, but the top and bottom of it is, marco likes his amp, he likes what it does better than anything else he has had before, be solid state or what ever,and he is not alone, there are a huge number of people all over the world that share the same feelings, now what ever you can prove with test equipment its not going to change what they hear and like. i also share their views, i am not a romanticist, i dont use valves because i feel some sort of empathy for them, or their circuitry, i use them because they sound right! believe me, if i could get the same sort of enjoyment i get from my system using anything else, that was cheaper, easier to make and used less power consumption, i would use it without a second of hesitation!

and while we are on the subject of cross-over distortion, or switching distortion is what i think your refering to, i would think that that would be more of an obvious trate to your 500watt amp, and would be un-bearable to my ears! unless of course it has a large amount of that power in class A, SO WHAT IS ITS FIGURES, how much of that 500 watts is pure rms, or is it all music power figures.

What is your beef anthony

marco likes his amp, there are (should be is) a huge number of people all over the world that share the same feelings,

This is untrue, the number might seem big to you, since you are a niche market supplier in a niche market, but it is infinitely small compared to those using ss amps, and for good reason. Surely you are not suggesting that they are all wrong ? every single one of them ? :

believe me, if i could get the same sort of enjoyment i get from my system using anything else, that was cheaper, easier to make and used less power consumption,

I suggest that ss amps *are* "cheaper, easier, and more efficient", whether you can get the same enjoyment is up to you, but please don't hobble everyone else. Please allow them to make their own choices.

Must I be castigated at every opportunity for being able to form and support my own opinions ?

They know their kit is better. Surely you are not suggesting that they are all wrong ? every single one of them ?

Why do you object so much to me stating these obvious facts and having my own preferences ?

Must I be castigated at every opportunity for being able to form and support my own opinions ?

jc,
you know, and i know, that the majority of people use ss, because its convenient, and because most of the younger generation coming into the hi fi market have never heard valve equipment, but as with marco,[see i still class his age as young] as soon as they have heard what valves are capable of, they stick with it!
i have no beef with you jc, in fact i have stuck my neck out on this forum defending you and what you say, it would seem to some, maybe more than i should have, but the top and bottom of it is, you only seem to answer the posts/threads where you can see a way of shooting down the other party, we never get straight answers and facts to the important ones put to you, why is this?

[Ian Walker]

He's been, but he left early to write that post.

I reckon he's gone back to pray for forgiveness

[jcbrum]

Well sorry if you feel that way Anthony, it is quite proper for you to defend me against the more unreasonable and technically unaware elements on this forum.

I feel that if Marco loses his control he will simply lash out from frustration, so I don't want to discuss it anymore.

I have done my best to give answers to questions and I cannot atm recall any avoidances.
