That was my thought too - does PS Audio look to slide in the Bridge 2, into the carrier, or rely on others to make the bridge cards and then provide the external connector (the bridge box) which quietens things down…
Seems like a lot of effort to just house the old Bridge 2 card, compared to making the carrier just a bit more adaptable so it can house the newer Converse “bridges” that can do DSD256, PCM384 and MQA unfolding to 384 (and which will probably allow upgrades in future years).
