This I had so presented exactly as I had been looking for a solution to this problem, and now I can say that even exceeded all my expectations.
The package arrived and when I saw it was the power supply is greater than the adapter, I was taken aback.
Then I connected the adapter to my system and the tablet made the connection and hear because .....
"That was right music"!
The sound quality is almost perfect!
I have the pleasure of my "sound drivers" are driven by an extremely rare Concerto Bayreuth stereo from the 70s.
Who is allowed to call his own a high-quality vintage system, looking what I'm talking, because this sound quality is no longer achieved by today's digital Ohrenquälern!
The combination of old with new technology in this case is absolutely first class and has convinced the skeptics in the half year where the Advance adapter is integrated into my system.
Anyway, I can say as a conclusion my strong buy recommendation for this adapter!
Very easy and intuitive to connect, create Bluetooth connection and off you go into the listening experience.
I would like to conclude add, that I could not connect the adapter directly to the amplifier, because the distances between the RCA connectors, which are located on the adapter, not in accordance with the agreed basis of the RCA connectors on the amplifier.
So I've made from a virtue of necessity and produced by RCA extension cable connection.
The distances of the RCA plugs (center 14mm) should be included in the description, so you, if necessary, can use an optional cable to advance.
Because the adapter is so small, it can in many places (behind cupboards, or shelves) are conveniently hidden.
Next year I'm going to buy another adapter for the garden shed.
I hope this review has been of you and wish you much fun with the Advance Acoustic Bluetooth aptX receiver!
