i am looking for headphone amp, and i found these two products. rpx33 is more expensive, about 1330 usd, gcha is much cheaper, 499usd; is rpx33 much better than gcha?  please give me some advice, thank you!!

I had owned both at the same time previously (GCHA for a year, RPX-33 for 6 months). What are your headphones of choice? At 499USD, it's a steal for GCHA. For my taste, I prefer GCHA that sounded smoother and slightly warmer compared to the RPX-33. RPX-33 has better resolution and slam the hell out of the RS-1 and brought HD6x0 to a totally new level.

For the record, I liked HD600 with RPX-33, and RS-1 with GCHA.
