I think if you're in the market for new, portable speakers, options like these HK Novas can make sense. OTOH, I bought this
Belkin Bluetooth Receiver and added it to some already-capable, portable speakers. Granted, the Belkin device is not Apt-X compatible, but it's cheap enough to replace should I want to and it gets the job done. Also, the target market for these type of speakers (and, potentially, the quality they produce) wouldn't necessarily know, hear, or care about Apt-X.
