Ok the decision has been made - the HE-500 it will be :)
Now I have to find a fine matching AMP for it.
What would be the rule of thumb for Orthos - lamps or transistors?
Thanks for great help so far guys, really made a difference.
Also what place in USA would you recommend to order from HE-500 - preferably authorised dealer. Some trustworthy place (I am in EU dont know your brands and dealers so hence my question).
Everyone and their mothers will recommend you buying from Justin (HeadAmp).
