I own Grado SR 225 and i'm thinking about buying a great for the price headphone amp.
I'm looking at the qinpu A3 amp but would like to know if theres anything better if i would pay a little bit more?
What about something vintage thats not expensive would i get better quality and warmer sound?
I'm listening to Beatles, Guitr related stuff (Satriani,Andy Timmons) Blues,Rock...
Thanks!!!
