I've recently purchased the C&C BH from ebay and it doubles the perfomance of the JDSLabs C421 for almost half the price. It's a top amp. Battery last 80 hours from a single charge! I can't wait to put my hands on the $300 C&C XO2 for an A/B.
As we proceed I'll let you know more details about this little gen, that beats amps that cost twice as much. It has the performance of $300 amps, with the resolution/detail/clarity of much more expensive amps. If you live in the USA you can get it for just $99 and odds are that in your country you don't pay customs tax. I think the same applies to Australia.
The C&C BH is a BIG BIG BIG step up from the FiiO E11. It makes the E11 sound completely muddy.
Some pics:
GC stands for Low and High Gain, LF for Bass Boost (very effective) and SF for Soundstage Field (it increases soundstage width and depth).
The provided copper/silver cable sounds terrific, great value compared to the $5 FiiO cable.
For just $99 this is a no-brainer for the audiophile in a budget that wants to try high end amps under $100 (impossible before the C&C BH launch).
C&C is a chinese manufacturer, hence the low price. This amp could very well cost $200, since it doubles the performance of the $180 JDSLabs C421.
It is just the size of a credit card, but its all metal, feels heavy, durable. Build quality is excelent.
