But I wanted to have the DAC function in addition.
Upon receipt of the E17 I begin to adjust the way I did with the E11, pushing a little gain adjustment> it was not going at all: loose tonal balance, its too aggressive.
In presenting all settings to zero, I realized that the sound was more "clear" as the E11 and the gain as I pushed on the E11 is actually a trick to compensate for a more "veiled".
So I gradually made this new amp that also expands the sound space (say that the E11 knows transcribe a wide stage, but does not know the depth of return, that knows how to make the E17).
I admit I also try to make him sing my headphones Sennheiser 65O (300 ohm impedance), it looks very good for space, mids and highs, but the bass is not at the level where they should be, is reached the limit of what can push this amplifier.
This experience was still interesting> listening to one of my albums downloaded on this site I became aware of a strange phenomenon: I heard some sounds very slightly with a slight lead over the moment I heard "strong and clear "
It was enough to push a little research to understand I meant simply what is called the "pre-echo" which is a defect of compression.
So I did some comparative listening tests with different encodings to conclude that I could not envisage mp3 downloads at 256 kbps (which seems to be standard Amazon) due to the fineness of reproduction my listening system (including Fiio E17 which will have contributed to reveal these details).
To my nomadic plays I now considering compression ogg vorbis as 9, (some sites offer downloads to standard) and for the house I read the CD on the blu-ray player with the digital output drives the amp / DAC Fiio E17 and here the results are very high fly!
This upmarket justice to the physical media: get rid of his CD because we all encoded to save space (at least we did with lossless compression algorithms), it's a huge mess !
There is a rich sound on our CD as good material can emphasize where compression makes it disappear forever :-(
Xav '
PS: the same sites mentioned above also offer test files encoded at 24 bits / 96 khz> Fiio the E17 + 4 westone know exactly make "venting" top of these records!
