I haven't posted on here before but have been reading this thread with interest, so much so that I just got the E17/E09K combo, which makes for a nice upgrade from my previous Behringer UCA222 soundcard, which I had connected to a solid state amp. My headphone is a Beyer DT880 (600 ohm), which went straight into the SS amp's headphone input.
At the moment the E09 acts as a pre-amp for the SS amp, using an RCA connector cable from the PRE-AMP outs to the AUX ins of the SS amp and I still use the SS amp's headphone input. Not sure if this was answered elsewhere but I would like to use the E09's supposedly superior headphone input, without losing the SS amp's added amplification but, as a technophobe, I have no idea how to achieve this. My guess would be a second RCA connector cable via some adaptor style device, feeding the end signal from the SS amp's AUX back to the E09. Is there a simple solution to this? Is it possible at all?
Many thanks for your help!
But then you lose functionality of the E17's DAC. In which case is you really want to chain the E17, the SS amp, and the E09 then you might need to get the L7 attachment for the E17. This will give a Line Out option for the E17.
So Computer-> E17 with L7 --> SS amp --> E09 by a 3.5mm cable or RCA to stereo mini --> headphone.
