The Fostex Hp P 1 is one of the best dac amp combo for IDevice
If you use only for UM Miracle , I think it is good enough .
But with the Alo RX 3 B you can get more power in low gain and has better
Sound quality compare to direct with Fostex Hp P 1.
My second best amp for portable rig is Headstage Arrow 4 G , you can use Also
As your additional power amp for your Fostex Hp P 1
I'm hoping to make one portable rig although I do love have different toys.
If you are using a amp with the Fostex, so using the Fostex as a DAC, do you think it better than a CLAS with a amp? My thinking is if I am going to use a amp anyway, I might
as well get a dedicated DAC if I'm going to carry three pieces. Only if the SQ is better.
