I'm quite interested on these two portable amps, mainly because I might be looking for an upgrade from the FiiO E11 and because a relative from Indonesia will come by in a few weeks.
Since there are Jaben stores in Indonesia, I've been looking at their selection of headphone amps and well, being quite budget limited, I've settled between these two because they've got a DAC so that I can plug in into my laptop if needed. But the problem is that there are so few technical specifications available for these two amps that I'm beginning to worry about if they are worth it. I might not necessarily buy it but I just want some more info on these two amps.
Any detailed specifications?
How does the two compared to the FiiO E11? FiiO E17?
What are they're characteristics like sound signature?
Are they warm or bright?
How portable are they?
What's the difference between the two?
If compared to the holy grail of portable headphone amps such as the RSA SR-71, how do they compare?
Is it really worth the price of $170 and $305 respectively?
Is it worth the upgrade from the FiiO E11?
And could they efficiently drive my Beyers DT-880 Pro (250 Ohm) and the HifiMan HE-500?
I'm also open to other suggestions but only from the Indonesian Jaben catalogue.
Thanks and sorry for so many technical questions.
