That's correct yes so - to to add to the complexity of the whole thing -
if you're playing a MP3 file and you stream it over most Bluetooth
systems then not only are you streaming data which already has a loss of
quality due to compression, you're also compressing it again streaming
to the Bluetooth Device thus losing more quality.
There is a method of Lossless Bluetooth transfer available in the APTX
Bluetooth profile but I've seen very vew devices able to support this
let alone receivers at this timeand IOS devices do not support it and
won't as they don't have the necessary hardware to.
the Samsung devices such as the Note4 and S5 - I assume too the S6 -
support the streaming of Bluetooth APTX and the ony speaker I know that
supports reception of it at this time is the Bowers And Wilkins T7, I'll
do some research on this as I'm sure there are more devices available.

As I understand the thing wifi is lossless streaming. With Bluetooth the
data has to be compressed in order to allow it to be streamed across
Bluetooth. This means that you lose sound quality as you have already
mentioned you experienced. This is not the case with wifi as I understand
it.
For example: if you take a song in .wav format which is lossless and the
same song in mp3 format which is in compressed form, you will see that the
file size differs substantially. The less compressed it is the larger the
size. The same thing during transmission.

So, if I plug one end of a cable into my iPhone's headphone sock and the
other end into my hifi's aux input, that will be lossless and when I stream
with my Express it will be digital? is the difference then analog versus
digital?

To put it bluntly, think of Lossless Streaming as if you had two devices
each connected by a good quality physical audio/video cable or cables.

Hello Dane and list
Well, let me disclose my ignorance: what is meant by lossless?

You have to get Bluetooth adapters and receivers that are capable of
Lossless Bluetooth streaming and most are not.
Its pretty hit and miss when you're talking about streaming via
Bluetooth when the devices are in different rooms.
And finally, the iPhone is not capable of streaming Lossless Bluetooth,
a lot of the newer Android phones are capable of doing this and they
include the
Samsung Note4, S6 etc, that's why a lot of mobile phones use either DLNA
or AirPlay depending on your choice of phone, the streaming is lossless
and it can be done over longer distances though granted usually you have
to have a Wi-Fi network as your foundation when doing this..

Hi all
Changed the subject line but to some extent it is still related to the
lossless streaming of music.
Is it at all viable to use Bluetooth to stream lossless music from two
rooms situated next to each other.
This might also be an option for me to use.
Unfortuantely my situation is a bit more complicated than usual. I
have an
induction loop system in my flat through my computer’s speech also has
to go
in order for me to hear it. The loop’s input is connected to my
hifi’s
output also. So I need to find a way for my computer’s speech also to
go to
the next room!!
So Wifi may not be the way to go? I suppose FM transmission is not
very
good at this stage? That is why I was also thinking of using
Bluetooth?
