It's sold through on their website already :cry: I look forward to testing this against my sh-8! Fingers crossed it hits amazon fairly quickly!!

@shenzhenaudio Do we know if this will be truly balanced? Does the claim for 3 watts come from the single ended jack or xlr jack?
It has not been released yet, we just open the channel to let you guys know. we will announce the released date soon. It's not truly balanced, 3watts from single end jack, also from xlr jack. :)

@shenzhenaudio what happened to the SP400? Are they going to tease with a couple of renderings and skip to another product like they did with the SP400?
