Hi, i have just bought a sennheiser hd 598 because the last week i tryed it in a shop, i liked a lot his sound, but i hink they were conected to an amp; I have a soundmagic a10 amp, which usually adds more bass to the headphones, but i dont know if it will be enought to amp a hd598, so now im looking for a good headphone amp, that adds more bass, i only play music on a sony a828. I have found some amps which are fiio e9, udac2, and ibasso d4 mamba(this one is expensive), do you think this amps would improve the hd 598? or is not worth to buy an amp for this headphones havin a soundmagic a10.
thanks and regards.
