Miccus Home RTX - Bluetooth transmitters

I am looking for a Bluetooth transmitter that I can connect to the REC OUT source on my McIntosh C220 preamp so I can transmit whatever is playing on my wired stereo to a Jawbone JamBox or other Bluetooth-capable, powered speaker that I can carry to another room (like a kitchen or bathroom). Miccus Home RTX seems to fit the bill. Has anyone used Miccus Home RTX or any other Bluetooth transmitter for the same purpose? If so, is there any significant latency (or delay) in the sound comes out of the remote speaker? Any suggestions greatly appreciated.
