In the previous installment I described the first trials with the first high definition file found on the Internet.
I felt the need to buy a new "source" because the media player which I used only has Toslink optical digital output, which I occupied the only optical input of the DAC, formerly occupied by the CD player.
In this way I could not listen to the CD, or purchase a new mechanism with coaxial output, or a new media player with the same output.
The choice fell on Netgear EVA9100, a media player on the card very complete and sufficiently recent, that he had the fateful coaxial digital output. The EVA9100
externally is very well done, gives the feeling of strength, good materials and attention to detail. At the practical test is fairly complete, although the interface is suffering a bit 'of the will at all costs to be used by anyone, even by those who should keep away from these objects.
Ultimately, the price super price I found online that finally convinced me ;-). Also with Netgear I was always good, especially for updates. About firmware updates, as well as punctuality guaranteed by the support of a large media company, there's a downside: once the product has been replaced by the next most advanced product, support firmware is decreasing rapidly to zero .
I connected to the DAC through the EVA a cable RG59 type of all4u double shielded by 5 meters (!). It took a long cable so that the EVA ended up in the cabinet of the tv and not in the hi-fi, however, since the EVA is primarily for the video. This cable has nothing special, except the length and double screened OFC more to the center conductor. My main concern is that not coming to the proper signal to the DAC, but apparently everything works up to 192 kHz.
Regarding the jitter, ie the time axis distortion of digital samples, I think the MF A3/24 DAC has a buffered input and make reclocking data, so do not be afraid. The files come
EVA via wi-fi. The adapter will have to buy separately. This is a really bad choice by Netgear as the EVA9150, released months before 9100 and that only the internal HD in addition, has integrated wi-fi. These are the typical savings on production costs that are not worth the savings they provide.
The EVA supports FLAC files, so you must convert them to wav advance, though for now I suspect that it is better to convert them.
The sound is excellent. With high-definition audio seems to have another system, and indeed another room!
In the next episode we'll see how we can further improve the system because of what the market currently offers.
PS: I unfortunately happened on several occasions that there is any problem with the EVA and files bit/88 to 24 kHz. After a few seconds of playback, the sound is suddenly disturbed by brownouts, as if loss of data. No problem with the old Trexstor. I contacted Netgear support, we will see what combination.
Meanwhile, I heard a new HD disc that I bought (24/88) for piano by Trexstor and optical digital input: Very good. Finished listening, I tried again the EVA via coaxial ... I thought enormously better! Unfortunately, the lack of disturbance persists, then I could not go more than two dozen seconds of music.
