So is that 22-pound box optional? Could I just plug this into my 'stat amp without it?
Since it effectively doubles the price ($2,600 EUR), I'm reminded of the H2+ which "actually" costs $3000 USD when it's all said and done. Of course you don't have to use the transformer box in theory. With the ERGO AMT on the other hand, it comes with an adapter to use with speaker amps figured into it's $1000 USD price, but you can spend an addition $500 to $2000 on a dedicated driver unit to improve performance.
