Since the db levels of the MFIT and ALAC versions are different (MFIT is a tad softer), they need to be matched up for listening comparisons...dang it, this was supposed to be easy. So far there is little to report...the only differences being because of the db level, and now those differences are gone.
One of the benefits of MFIT is the ability to check for clipping, which can be a problem when converting to AAC straight from the CD master. I used iTunes to generate my own 256kbps
The image below shows a comparison between the MFIT (Mastered for iTunes) and ALAC (Apple Lossless Audio Compression) versions of John Mayer's "Queen of California." This is track 1 from his latest album, Born and Raised. MFIT is on top, ALAC is on bottom.
What do you see? To me, the MFIT version is mastered at a slightly lower volume. I can't see any visual evidence that the dynamic range compression is different: since the loudest and softest parts both appear louder
From their customer service rep:
"...we plan to add more FLAC content going forward, but currently we only have a few other FLAC releases in our stores. Please visit our dedicated FLAC page for further information and to view our FLAC releases."
The February edition of Stereophile includes a review of this album, so I was pleasantly surprised to see that Rosenwinkel's website sells digital copies in Apple Lossless format.
There doesn't appear to be much information available on the BT100 blu-tooth device, so I asked them for more details. See below for CA's response:
The maximum audio resolution supported by the BT100 is 16/48.
The apt-X protocol used is the standard apt-x bluetooth.
However, your music will still be upsampled to 24/384 via the BT100.
