Your ears would not be able to tell the difference between using a 3.5mm connection or an RCA connection
Technically, the 3.5mm to RCA cable is not using a "splitter", a splitter would be splitting the signal, which is not what a 3.5mm to RCA cable does.
The 3.5mm to RCA would be more referred to as a Y cable.
So you do not want to use a Y cable, you just like the idea of using an RCA to RCA cable.
Which is fine, you can get the Fostex and use an RCA to RCA cable.
We just do not know what DAC (Digital to Analog Converter) chip is used in the Fostex.
But I do know that the Hifimediy U2 uses a Sabre DAC chip, which is going to be a fair bit better then whatever is used in the Fostex.
You can also buy a nice looking 3.5mm to RCA cable (10 GBP) from the same people how sell the Sabre U2.
Thanks for this info on the DAC chip, very helpful. One question about the Hifimediy, if I want to plug my headphone directly into that, do I still have the benefit of the tone control/EQ from my computer? Or is that defeated? Thanks.
