Questyle CMA600I Balanced headphone amplifier and digital audio converter

I bought this as an upgrade to my modi and magni I noticed a difference in the bass and a couple of songs were completely differnt in a good way the least difference I could hear was in rock music apart from the base guitar being more in the mix. All gains were small for the amount of money you have to pay as the diminishing returns hit you the more money you spend on audio equipment. The amp/dac came very well protected I think it could of withstood a small explosive charge.
