Yes. No EQ on all three. Sennheiser HD595s. Boof!, by Tony Remy. Volume output set as close to the same as possible.
I like the Sound Quality on my Zune better, imo the iPod hisses at loud volume's and can be a little screechy. The Zune sounds more natural and balanced. So without any additional apps or Eq's I prefer Zune HD over iPod touch... but it's not the biggest of differences
Also I've got MDR xb700's and FiioE6 [soon to be E11] to boost my sound quality and I only listen to music and watch Videos so I could care less about "apps"
I'm with you there! A small part of me just doesn't like Apple Products so I buy everything but Apple ;3 still though I'll upgrade soon enough! My iPod is a Audio Book host now and soon enough Zune will host Videos[Videos are really nice on Zune imo] while a new source gives me AWESOME Audio Quality!
The Zune HD via dock line out sounds as good as a Nuforce HDP's DAC which is a $450 dac/amp combo. I fed the Zune HD into the HDP using 3.5mm and compared the USB DAC of the HDP and the zune through the headphone amplifier of the HDP. I could discern no difference using a AKG K701.
How are you using the Zune HD optical dock output?
