Harman Kardon BT receiver in Benz e-class works very good.
"High End" Bluetooth Receivers - Snake Oil?
I've been doing some research on the net, and came across a post somewhere (wish I'd have bookmarked it, because now I can't find it again) talking about Bluetooth receivers, lossy compression, etc., that wasn't very complementary of the "high end" receivers. Of course we have the positively reviewed Audioengine B1 with the AKM "Miracle" DAC, the Auris BluMe with the same DAC, the Arcam rBlink and miniBlink with Burr Brown DAC's, and others with the Wolfson DAC out there on the market claiming "CD quality" sound.
I'm far from technical, so this may be askew, but evidently, given the compression and decompression algorithms, lossy this and lossy that, low bit rates, and other inherent limitations (including AptX), Bluetooth audio can only be so good. The up-sampling, high bit rates, etc. of these "high end" receivers/DAC's is not capable of restoring or elevating Bluetooth streaming to anywhere near CD quality levels. Supposedly it has to do with the compression algorithms that simply cannot be fixed with up-sampling, etc. I guess like a sailboat, it's speed is limited by physics, so no matter how much power you have, it'll only go so fast.
Thoughts?
