Re: Do the power tubes have same impact ?

Thanks for your post,it is an integrated amp ,driver tubes are a pair 12ax7 and preamp stage tubes are a pair 12au7,it is an automatic bias circuit, well in the burning period of KT88 power tubes (100 hours 3 weeks,5 hours average listening a day,)I hear some developments
in a good manner of power tubes, but this is different, the music I play was more realistic but now is more hifi simplest way to describe,and I am sure I will get the same realistic sound if I put on new set tubes 5-6 mounths again but then I will notice the differencies on exact cds, this maybe my amp's fault if nobody find same differencies, maybe tube manufacturers do not produce same quality tubes as NOS today?..
