I've loved the KSC75 for years and their sound sig is one of my favorites. I'm hoping to upgrade to something similar but with more presence and detail. I have a pair of grado sr60s with Lpads but I still keep coming back to the KSC75. I do like how the sr60s have more impact if even not quite as detailed on the higher end. Mainly in wondering if the HD598s would fill that void and if there were any more suggestions. I love punchy bass but not bloated bass. Smooth mid range with detailed high end is always my preference. Thanks in advance!
