Categories: EVA9150 & EVA9100
I just read about the EVA9150 on Gizmodo, and it looks like a very nice device.
I looked through the datasheet and webpages, and couldn't find an answer to my question, so I hope someone here can help me. Does the EVA9150 support high sample-rate files, like 96/24 FLAC or 192/24 WAV? That is, can it output bit-for-bit accurate high-rate PCM from its S/PDIF or HDMI ports? It seems to have enough bandwidth given that it does 1080p from HDMI, so I'm hoping it can. It would be one of the very few players out there that do this.
The sample rates I'm interested in are 88.2, 96, 176.4, and 192 kHz, all output at 24 bits. 2-channel at the minimum, 6 or 8 channels would be amazingly cool.
Thanks.

United StatesThis is an excellent question, and I apologize it wasn't picked up by anyone in the community as of yet. I'll see if I can pass this on to some technical folks who might be able to help answer your question.

United StatesHaven't heard anything yet, but will continue to try to get an update. Thanks for checking in!

The EVA 9150 has been tested with the 192KHz @ 24Bits, 2 Channels and supports this. (I'm assuming it will also support the lower bitrates, but it wasn't tested against these.)
I'm one of 9150 tester and I can confirm it play 192Khz@24bits WAV 2 channel.
I haven't tried the other (more than 2 channels,flac and HDMI output for this) but I think there should be no problem. No one in the testers team have reported issue or problem in this area all along the beta period.
I'm sorry because I'm out for work and cannot make some test for you right now. But when I'll back to home (in the next 15-20 day)I could give you more precise informations about it.
Hi,
I can play 96KHz/24 bit Wav files but not 96Khz/24 bit FLAC files through my Netgear 9150. 16 bit FLAC seems fine. I have not tried 192KHz/24 bit as the Naim label site only supports up to 96KHz and I was trying to solve that problem first. Also the Naim site does not say whether they are two channel or multi channel which doesn't help fault finding either. Has anyone else had this problem with the Netgear 9150 and is it just a 96KHz/24 bit FLAC issue or general 24 bit FLAC? In case anyone asks I also have the latest official release of the firmware.

The EVA9150 not being able to play 96Khz/24 bit "Flac" files is a known issue and has been submitted to engineering previously. (Note: This may also effect higher bitrate Flac files, but they haven't been tested yet.)
Hi,
It does affect higher rate FLAC files. I can play 192/24bit Wav but 192/24 bit Flac actually locks the system up and it has to be powered down to reset. It is a significant problem since I along with many others have standardised on FLAC as its open and compresses reasonably and high quality labels supply in FLAC as standard in 24bit. Is there any timescale for a fix for this problem?
This issue has been submitted to engineering along with sample files, but there hasn't been any information yet on when this will be addressed. Most likely when this gets addressed' the first place you'll see it is in a beta firmware over in the Netgear EVA9150 beta forums. So I'd recommend keeping an eye over there for any firmware updates.
"The EVA 9150 has been tested with the 192KHz @ 24Bits, 2 Channels and supports this"
Supports 24/192 _without_ downsampling, i.e., it passes all the 24/192 to the DAC or AV?
Are there already any results on the Netgear investigation on this issue? I bought the eva9150 on results I saw for others media players based on the Sigma 8635 chipset, which played Flac files with higher bitrates quite well. I hope Netgear will adress this issue and improve the EVA.
Actually the support for 192KHz 24 bit Wav and Flac files was added in beta 2.4.16:
- Support for 24-bit, 192kHz WAV, FLAC
If you are running this beta version (or later) and are still having problems playing these files let me know and I'll flag it for engineering to look at again.
Same here but at the moment its pretty useless for anyone who wants high audio quality in an open standards environment. I'll give it another month and dump it if there isn't some movement on this pretty basic 24 bit 192 FLAC requirement. Shame as its OK at a lot of things.
That is very good to hear about the beta version and 24bit 192Khz FLAC. However when will it be at product quality? I don't have the time to play with beta's and the inevitable problems but I do want this particular feature as soon as possible and then I would be happy to keep the 9150.
Actually the beta firmware is very stable, so I wouldn't worry about going to an EVA "beta" if this is a feature you definitely must have. The betas are more a way to add additional features or fixes, and then every quarter or so a beta is assigned as an official release. This allows the end user to get their hands on the enhancements quicker, since releasing new firmware requires a fair amount of time (and paperwork).
Also if you check out the EVA9150 beta forum (at Netgear.com), you'll see there are many users that have been using the betas for a very long time without any real issues.
Ok the beta works fine for me. I got a recording from Linn containing 24bit/96kHz FLAC's, and now it plays fine. I don't know though wether the internal DAC also plays it in this quality, or if I have to wait until I have a quality outside DAC which can play at 24bit/96khz or higher (such as a Cambridge DAC)
Thanks though, I am know able to play ALL my music... :-)
Hi,
Is the ablity to play FLAC 24/192 and 24/96 (to SPDIF, without downsampling) sorted out on the current production vers, does anybody know please? As A Y said, it would make it one of the few players that can do this incl Sonos and all Squeezeboxes though the touch will play 24/96 without downsampling it.
Thansk for any insight,
