N803 looks to be discontinued, any replacement that performs as good or better?
Definitely not discontinued. I live in Malaysia at the moment, where they are made.
I was looking for it months ago, and since I can't find it, I called Yamaha Malaysia. I was told they were coming.
Last month came out a new batch.
The reason why they are hard to get, is the same reason why almost all electric components are being hard to get nowadays, the Covid situation really messed up the shipping of components around the world.
I got mine in October (was hard to get as well) and as soon as they came out (at least here in Kuala Lumpur) they sold out quite fast.
I must say, for the price you can't beat it. Is a truly magnificent piece of equipment.
