I wonder if you could advise please. I have an HTC One and a Macbook Air which I fairly regularly use as a source paired with my Sennheiser Momentums. Sounds pretty good.. but I'm getting greedy and after much trawling of this forum I've discovered that such a thing as a portable DAC /Amp exists. I'm a little clueless as to whether or not sound quality would be improved by adding such a device, so I wonder if you could advise on these questions please?
1. Would adding a DAC improve significantly the sound quality of the HTC One and Mac?
2. Do I need an extra Amp at all given that the Sennheisers are very low impedance?
3. If I can get a decent boost to SQ, what would the best DAC / Amp option be? I can spend up to about 300 USD if necessary, but would rather spend less
4. I suspect that I don't actually need anything that's overly portable as I'm not sure that I would be able to pocket the HTC AND another device, so it might end up being something that I just use at home or lug into work in my bag. So transportable, sure, maybe not completely portable if that makes sense..
Hope you can help, any advice gratefully received!
