Thank you for the answers!!
Burtomr, I thought about it, but I think i prefer to invest in an additional amp that I could use with aother DAP in the future.
Bflat, I´m sure the RSA SR-71B amp is a great option! But, does it produce some hiss with the Shure 846?
Warrior1975, does the Cayin C5 produce some hiss with the Shure 846?
Thank you very much again and sorry for my english......lol
