Such good specs, barring the Bluetooth 3.0 implementation. Just why are most of Teac's products stuck at 3.0?
Also, I have quite a number of CDs; would have been sold if this had a changer. At least a 3 CD changer would have been great.

I don't know that Bluetooth 3.0 matters. IIRC 4.0's main innovation was related to power and distance. It still has AptX.

Yup, and don't signal power and distance matter?

By power I wasn't referring to 'signal power', but power usage/energy efficiency. Not really relevant here as this is not a battery-powered device. As for range, turns out I misremembered an old article about that. Which makes sense. A protocol change alone shouldn't affect range.

Oh range definitely is a variant with protocol version @bilditup1. In fact, one of the major revisions of BT5 over BT4 is range!
I agree with you on the power front on the transmitter, since it'd be hooked to AC. However, for BT4.0 LE, both the receiver and transmitter must be capable as well (though I have mostly seen sensors to use LE). Since the TEAC's transmitter is only 3.0, it would neither be Low Energy compliant, not have the transmission bit rate (24Mbps) advantage. However, this is irrelevant if LE is not used for audio devices, but yes, protocol revisions do bring about range enhancements.

Hmm. Re range, that means it must be a hardware level change. In any case BT3.0's should be adequate within the same room. Regardless, I can just try it and report back (not home atm though). Right, I didn't mention LE as I didn't think it was relevant. Max bitrate is the same between 3.0 and 4.0, but regardless nobody is making use of it in the audio domain.
