Any matrix m-stage love here? I love my m-stage for it's colored/warm sound. That might be what Okamoto is looking for. Has anyone tried this pairing as I'm interested as well. I plan on getting the he-400's soon. I don't mean to barge in here, but I've been eyeing this thread for a while. I suspect it to be the cause of my overwhelming desire to get the he-400.
Plenty of M-stage love here. Awesome amp for the price, pairs really well with the HE-400.
It is quite long like someone mentioned, but that suits my desk better.
