~ Observed from various completed online bids. Your own results may vary. Read the buying guide for more info.
~ Some people sell directly from Japan where the speakers are cheaper, but shipping them is expensive.
~ NS-10M are the oldest model and price range is large depending on condition.
~ MT's were the only model sold individually, (for 36000 yen each) and thus do not come in matching pairs.
~ It's recently been confirmed by a site visitor that they are indeed interchangable.
~ However the JA1801A (XN542AA1) cost more than the JA1801. I'm trying to find out why.
~ However, I have never seen this in reality and believe it to be an error.
