High res streaming

Posted by: TheReefManiac on 08 September 2015

when I play 188  24 bit high res the music is choppy in some places but in 96 24bit it's fine this occurs in mostly Usb connection. I have a dac vi and aurelic streamer. Remember just the upper res has this problem!

Welcome to Naim Forum .........

I suspect it cannot stream the high density data from whatever is feeding the DAC- Vi USB input........ 188k is a problem but 96k is OK

It might be the USB cable,  but more likely is what the data file is stored in - what is that ?  PC, Mac, NAS, USB drive ????

Nas drive

I need to understand how your system is connected 

How are NAS, Aurelic & DAC-Vi connected (how is each link connected - ethernet / USB / wireless) & how is the wireless/wifi router connected,  & what is the control (how do you select albums play from NAS)

I've not come across 188kHz sampling rate. Usually Hires sample rates are multiples of either 44.1 kHz (88.2kHz, 176.4kHz etc) or 48kHz (96kHz, 192kHz etc.)

I'm aware that HDTracks have sold 188kHz.

Its a bit odd & I might be tempted to convert to 96kHz,  the SQ difference is negligible.  

 

Both the DAC & Aurelic indicate the USB can handle 44.1 to 384 KHz at 16 to 32-bit Other inputs are up to 192/24 per S/PDIF standard.

It might be S/PDIF has issues with 188kHz

The 188 is quite odd and might be the issue. It's not a regular sampling frequency. Otherwise you would need to give more background on your setup. But as you say the 24/96 is good it might be just the 188 thing, did you try 24/192 and experience the same issue ?

My mistake it is 192.

Also would there make a difference if I wired the ethanet instead of wireless

Let start again the numbers mix me up. Yes it's 192.   Sampling. Keep in mind I will play an album it plays half flawlessly then all of a sudden a song starts to break up then it smooths out! So it does work just not all the time. I don't know if wireless connection is affected when playing the 192 sampling. I just would not think that's the issue. It's a real mystery

AAAAAHHHHHH  !!!!!  

Wireless - the spawn of satan 

Yes, ethernet will always handle high density data better than wireless.   Search the forum & you will find many cases of wireless having 192kHz breakup issues, mostly OK with lower sample rates & completely fixed by ethernet connection

 

The basic ethernet connection is ...

NAS - ethernet - router - ethernet - streamer  

Depending on the spec of your wireless router, it can be further improved by installing a switch between NAS & streamer & a branch off the switch to the router.

Can you tell me what to buy for this and how it will hook up please

Posted on: 08 September 2015 by Mike-B

You need two ethernet cables - but what have you got already & how is it all laid out

What is the distance & how is the room layout from NAS to streamer

What is your wireless router (make/model) & where is located irt NAS or streamer.

Around 75 ft

Att router and net gear nas

Posted on: 08 September 2015 by TheReefManiac

Streamer is in living room and computer and nas is in the other bedroom accosts the house 40 ft in a straight line

All you need to do is connect ethernet cables between NAS to Router & Router to Streamer.  

However going through or under walls makes it not so simple. I can't tell you how to do this as I don't know the house,  it might be possible go under the floor or the through ceiling, you might be able (willing) to route the cables around the skirting & through door frames  or it might need to have ethernet wall sockets.  If you are not able to do this work,  get someone who knows ethernet installations to do the work. 

I would advise to get at least Cat5e - Cat6 would be better. But don't get tempted with the exotic cables (snake oil)     I don't know where you live but sense your use of feet measurements & AT&T router you might be USA - if that's the case I would recommend Blue Jeans Cables,  they make in house to your spec, use a quality Belden cable & test each cable & issue a test certificate.

Thanks for your great advice. I will have AT&T install an Ethernet jack by my stereo system. Thanks again
