They're brand new, so no. Only products that I'm aware of are the upcoming Monoprice THX desktop and portable, as well as this Topping DX3 Pro. More to come but so far it's just a handful of products.
The 4490 probably got slightly cheaper with the 4493 out now, so for cheap manufacturers the 4490 is an even more attractive offering than before. AKM4493 will be premium devices only that do not opt for the 4497 flagship (which needs way more power). About the 4497, I don't believe Amir ever measured a device using it
the
SMSL M10 comes to mind. Then again, since the RME ADI-2 uses a single 4490 chip, I'm not sure the 4497 would be any better (but it
is their flagship so I'm still curious...!)
