thanks for the fast reply mate.
Another query, I've read a lot Regarding this topic but couldn't come into a definitive answer. Are x1 and x3sg Almost indistinguishable in Term of sq? Should i buy x3sg or x1 with e07k Will give me same sq? I wonder how come two completely different chipset give such "almost same" output?
It depends on how you listen to music.
If you use the player only with a nice earbud, it doesn't matter.
If you use it in a car, it doesn't matter.
If you mainly use line out at home with a nice amp (or another portable amp), it might gonna matter a bit.
Also, if you wanna use it as a DAC, then it is not a question.
I use it LO with an amp mainly at home, and I need it as a DAC as well, often. So for me X3 without a question.
It depends on what you need mate. For the same money, you can buy better DACs. But they are just DACs. X3ii is a player and a DAC. (And for the money it is awesome.)
X1, and X3 even more has a very clear LO signal. X3 is even better. So, if you wanna include an external amp in your system, which is over £100, I would say pay for the X3ii's higher price.
If you are an earbud guy, and worry not much about amps, then go for theX1.
