@thefitz I still think in blind listening tests, if the sound signatures were identical between two hypothetical devices, one a full sized portable DAC/amp say the size of the HA-2 and the other one the size of the built in devices in the Cypher, I don't think any sound quality differences would be audible simply due to the difference in form factor sizes. Sure if there was significant overheating, or improper shielding, perhaps, but I don't think there is really any difference purely on size alone in this case. I think for Apple users the Cypher must be a brilliant step-up which is what it was meant for.
