Intergrated SET amplifier with 2a3 power tubes. Upgraded coupling caps to Auricaps, internal wiring replaced with pure silver Teflon signal cables, dampened chassis.
Good to know about your Fostex drivers, Djdonis. I'm at that critical window right now in which I'll soon be learning that either a) break-in is a real and significant process on Zus or b) they're not as good as my ~1K monitors. Time will tell!
Nice system -- simple and clean. As an aside, can you recall the break-in period on your Omens? I just received a pair and we're at 50 hours. They've got the dynamics thing down-pat, but aren't disappearing very well or creating a believable soundstage. I guess I'm just looking for reassurance that they'll come around with more playing time. Thanks for any comment.
