So to sum up, we have:
1. Enough power to run the toughest headphones, though the only offered power spec is 6.25mW.
2. An amp that runs slightly warm to the touch while supposedly generating huge amounts of power.
3. An OTL with high output impedance masterfully driving low impedance headphones.
4. A new method of driving a tube that generates huge power while extending the lifespan from 1,000 hours to 100,000 hours.
5. All of this powered from a battery.
It doesn't add up.
If there is an explanation, it is time to tell everyone.
Having owned and enjoyed my Continental now for a couple weeks, I've read this thread of mind-numbing, techno babble with great interest.
Obviously, there are better headphone amps out there, such as the Cavalli Liquid Fire at the high end and the Schiit Lyr (which I own) at the moderate level.
But the iPod/Solo/Continental comb delivers very, very pleasing sound to my Audese LCD-2's relative to its tiny form factor weighing only 1.5 lbs., enabling me to have some great music with me as I travel and even when I'm playing catch with my golden retriever in the back yard. It is a trade-off.
I don't know how the iPod/Solo/Continental combo does it, nor do I care. Maybe there is a mouse running a treadmill inside the Continental's case. But it sure sounds good to me. Amazingly good in fact. As an Absolute Sound subscriber since Issue #1 (1974), I subscribe to Harry Pearson's core philosophy - "Trust your ears".
