I have several questions before getting a cheap headphone tube amp as a entry into tubes?
Do you really need a high end speakers to use with tubes?
no.....but it depends in your listening tastes/habits, how loud you want your music,
how big is your listening room, and finally how deep is your wallet...
the key here is to audition, audition and audition....
do not listen to others, make your onw mind as to what makes you happy...
Or even with normal speakers you will notice a difference already?
not sure what ou mean.....my asdvise is to get a speaker system first, one that you
really enjoy listening to...then look for an amp to mate with it...
Are all tubes pin compatible?
no.....
