What is better an amp/dac with LMH6643 or LME49860 for clarity and sound for sennheiser 598's

In general I would say that the LME49860 is better but if it's not the only difference between two DAC/AMPs there will be lots of other factors like the DAC chip itself. I would suggest you post your question on head-fi.org but ask about specific products with the 598s rather than a chip.
