I can't find myself having said something like that, but it sounds like some stupid shit I would say so I'll accept the attribution. Off-memory I think it was a KGSSHV (forget the config) that I found hot in the upper mids/treble vis-a-vis the 323S in a meet, and given the conditions I couldn't pay attention to much besides the tonal balance. The BHSE doesn't sound bright but one of these days I'll fire up the 323S betwixt sessions and hear what's what.
UK Stax distributors still have the original Omega earpads (not the bunk oversized ones)? I missed out on at least one pair of "NOS" non-oversized ones from eBay for ~$300US, so I guess proactive care from this point makes the most sense.
