ok guys im logging off, thanks again to everyone for the input and the help so far!!!

LOL thanks for the imput, so basically provided I buy some back-up valves with the amp (if that is possible from headamp) I may even go the valve route. now abut those O2 s I can't find anywhere.....

How do the biasing controls work? like are the simple to use or do I need separate equipment? to give you an idea I saw instructions on Conrad Johnson site that said u turn a screw til a red LED goes "just on" and thats it. is the KGBH that easy to bias or do I need to have various metres to do it?

this is one of the things i worry about with valves, I dont even know hot to measure DC V (ok maybe i do a bit LOL) but thats about it. the idea of buying something and then having to tweak it (knowing what i am like) worries me . This is why i prefer the SS way. as far as i know, if it aint broke, there is no need to touch anything!

Ok so how does someone bias them? (say on the KGBH?) also how about replacing them? another thing I hear is that different brands of valves change the sound, how easy is it to buy replacement valves of high quality?

I agree with you about that, what I am saying is this: if you listen to something once, then you stop for a bit and time passes, then you go back to it it may sound better because you have no other reference point at that moment in time. If I listen to one thing and then, after a long while, I listen to something else, I agree totally that your memory cannot really help in comparing one to the other. if, on the other hand, you compare two headphones at the same time and at that time you realise that one is better than the other (or you prefer it, whatever) you will not likely forget this over time. Spritzer posted a comparison between two headphones which at the time he compared them together made him choose the O2s over the 007 mk2s. He may not remember why one sounded better (although he does) but he remembered which he prefered. I'm saying that this is reasonable use of memory. Do I make sense or am I just spouting off again?

Hi elephas, I agree with you that memory may not serve to give a definitive description of the sound or a suitable comparison to something you are listening to now, but surely if you compare two different products together (as Spritzer appears to have done) and one sounds "better" than the other at that time, you will surely remember that (even though after a while you might not rememebr exactly why).

Hi again Spriter and thanks for the feed back! is it possible that this could have been caused by the mk2s not being burnt in yet compared to the original O2s you listen to? the truth is I am now seriously considering not upgrading at all or finding (good) second hand O2s

According to the reporter from StereoMojo on canjam 08, when he asked the Stax rep about a new earspeaker to fit "above" the 007 mk2s apparently he was told that "something" is in the works. If this were true it would explain the drop in price on the new 007 mk2s. Does anyone have anything more about this or does anyone know whether Stax is developing a new "top of the range" model?

Gentlemen, I'm logging off now as its getting late here, but I wanted to than you all for the great pointers and information you have given me over the past two days, I've learnt more than a weeks worth of surfing and reading elsewhere! Cheers and good night

So I gather from what I have read. I meant the O3 chronologially speaking though, not in order of greatness. I have read (espcially from you Spritzer, but also from a great many others) that the mk2 sound "tonally darker". I'm wondering whether Stax is planning a new amp to match them to that contrasts this, who knows:confused: Personally I'm going to try and see whether I can get my grubby little hands on the mark 1s!

OK I get it, I think I will just buy mine from Justin (providing he has them) and be done with it...... until the valve bug gets me!!!! (mmmmmmm, valves....) LOL personally i prefer SS, but there you go!
