There are some pretty smart people in the marketing department of CSR.(the company behind aptX), who have managed to give people the impression, that their codecs (aptX) gives you almost, near, like....CD-quality.

A quick look at the CSR homepage however reveals the facts:

And that is about all we can expect from streaming audio with the bluetooth 4.0 standart.

We see, that they talk about the audio format as being 'CD-Quality.

But this is even true about a 96 kpbs MP3 stream, if the source was a CD - they are both 16/44.1 then.

It is the bitrate, that matters!!!

CD-quality bitrate is 1411 (which is 4 times the aptX codecs).

As you would know 256 kbps can be comparable with the streams of Spotify and WiMP/Tidal (in the Premium versions).

How good the aptX codecs works is hard to test - I guess a MP3 stream with the same bitrate would offer pretty much the same quality.

Whether the convertion from one codecs (MP3/OGG) to another (aptX) is wise, I am not sure.

The guys from CSR surely have been very good at promoting their solution as the best.

Thank you @David that was most informative.

I naively thought that if you wanted seamless jumping then they would need to know about one another.

The wired network behind is still the same. The usual problem is that you cannot successfully extend a network wirelessly when the station to extend is already transmitting a weak signal. The best option in my case was to use a cable and let them transmit the exact same wireless network data.

So I could insert a small wired router in front of Uno and then connect Dos and Zero (should Cero😁).

You can at least try. Channels might differ, I observed the noise in the various channels here for quite some time and adapted them afterwards.

I have small spare routers anyway, however do you have any particular recommendation(s) ?

Nope, I use standard Apple models from the last (not latest) generation in dual frequency range mode (2,4 and 5 GHz) together with an AVM

Totally! The streaming codecs remain the best solution. The problems, often cited on this board as at the door or Apple's Airplay are mostly to do with the WIFI controller and network configuration. And this stuff is hard folks. The move to a new AzureWave combined 2.4/5GHz and Bluetooth integrated chip in the A9 has improved things and that resolves most of the problems. In my experience, I'm getting a solid 300MBps on 5GHz and 144MBps on 2.4GHz. Even then, you may want to consider one of the more recent AC3200 routers with 2x 5GHz bands and 1x2.4Ghz band to separate out the traffic. I'm using an Apple Airport AC which is only dual band, so have forced the A9 onto the 2.4Ghz band.

Pretty happy with the A9 G2 now. As a result, I'm a ready buyer of the new Essence with this same controller the moment it lands. Its also THE key reason I've not rushed at the Moment. And wiring up over Ethernet would be a bit of a Faf for me and add 20% to the cost of the purchase. I'm not paying an extra 20% to make a product work - thats madness. If they offered a free 1/2 day install service, I might consider it.

But if you steam Deezer on AirPlay or aptX, it makes no difference as their bit rate is only 356 mb anyway.

Two things:

1: converting from one lossy codecs to another might not be the best (though you would probably never hear that on a A2/A15).

2: if you are using an iDevice as streaming device, you won't benefit from a codecs like aptX, since iDevices have no support for aptX.

(Means - no need for 'an iOS'er' to deal with the pros and cons of aptX).

Bumping this back up since its early summer now.

The Beosetup for IOS app got updated last week with support for new devices, not sure what that is though.

Am hoping for 5Ghz wifi and airplay

Well I'm dreaming about WISA inclusion too. *fingerscrossed*

Maybe you should stop dreaming - I am sure the price for the 2nd Gen would have gone up, if that was the case.

But - maybe in a 3rd Gen 🙂
