Hi everybody! Greetings from Barcelona!
This is my first post and I want to thank the attention of anyone who responds.
I'm interested in buying a tube headphone amplifier, but I have a low budget so it would be interesting to hear some advice from more experienced owners.Looking for through the web I have ended with two interesting candidates: the Little Dot Mk II and the Appj PA1502a. Both have received quite good reviews (not many, but there are some) for the price so I'm undecided. The Little Dot is a class A OTL push-pull amp, while the Appj seems to be a class A transformer output single ended.
As for the behavoir with different headphone impedances this is what I got:
APPJ : 0.13W into 600 ohms 0.26W into 300 ohms 0.5W into 100 ohms 1W/32ohms
Little Dot: 300mW into 300 ohms 200mW into 120 ohms 100mW into 32 ohms
I can see the two amps have opposite power behaviors from different impedance headphones. That's not really a problem because I have to get a replacement for my dying old AKG k121 from the 90's, so I can buy new cans that fit the new amp (by the way, doubting between the more neutral Beyerdynamics DT 880 or the more temperamental Grado sr80).
So... what do you recommend from your experience? Any help wellcome.
Thank you very much in advance.
