network streaming tweaks

Posted by: vtpcnk on 03 January 2018

hey all, i just started using a unitiqute. so what are the things i can tweak for SQ?

1. nas. is a nas certain to be better for sq than a hard disk hooked up to a computer?

2. ethernet cables. i saw chord company has some of these. anybody tried that?

3. since i can control the music through the naim app, i dont need a computer with a screen. any benefit in using raspberry pi or intel nuc? lesser interference, traffic, jitter etc?

4. is there an audiophile router or rather a router more suited by its features for streaming music?

5. i am currently using asset upnp. is there anything better than this?

Anything else?

Appreciate the insights.

Obsydian,

certainly the chord music lan would add some improvement for the music, but maybe for around 10k you can have a better amp/preamp / dac or streamer combo than nova.  You can in that logic buy a 5 k power cord which will improve also the nova....

The gryphon diablo 150 is a one box integrated /dac amp and would certainly smoke the nova with a chord music ethernet, because the amp, preamp section is a lot more advanced.  For waf factor, it is also a beautiful box.

Anyway just my feelings.....    You can also try effectively the chord music lan, but will it really improve marginally on your nova, i doubt a bit.  On a 552/500/nds, the difference should be more clear.  But i have not tried, so why not, if you can return such a product...

I really feel the fibre bridge has as crazy articles suggest ditched all the noise. Cannot stress how much people should try this at sub £100 it is one of them try and decide.

 

So what are people using for the fibre bridge? I think I saw TP-Link stuff mentioned in an older thread (or was it this!)

For <£100 I'd be prepared to give it a shot.

I'm in this camp and so are all the incredibly clever research and tech people I work with. 

"Bits are bits; Ethernet transports error-checked IP packets from one point to another. There’s no such thing as a good bit or bad bit or “better-sounding” bit — you either receive the packet of data (the FLAC stream in this case), or you don’t."

Yes bits are bits, but they're carried along by an analogue signal in two pieces of wire (by using Manchester encoding) .

Along with the analogue carrier for the digital data there is, inevitably, comes analogue noise (variance in the amplitude domain) and jitter (variance in the time domain).  These effects can both then get electromagnetically (and, in the case of jitter mathematically) coupled into the sensitive analogue electronics of your system.

The bits may be bits, but that far from the complete story of digital transmission in a mixed mode system such as a DAC!

Huge, thank you for an informative post. I think I sort guessed these things without having the technical knowledge. Simon in S makes the case for the Cisco switches such as the 2960 on the grounds of much better timing and lower noise.

I assume Obsydian’s new and used 2960s differ in these terms. I would have hoped the degree of deviation for a properly refurbished unit would not have been significant enough to hear though!

One thing: how do the various cables help beyond the switch? Is there a logical reason why one cable is better than another? In what way can a cable reduce signal degradation.

Hi Phil,

Although I'm convinced of the technical reasons for differences due to the cable connected to the streamer, I'm much less certain of technical reasons for differences from points in the network system before the switch if the switch is screened and earthed.

I don't have enough confidence in any theories to make any suggestions here; so no explanation!

Sorry,

E

(However, I think it better to admit lack of knowledge than try to bluff!)

DAVEJ - Trade in : )  now you have me seriously thinking about it.

MR ROOSTER - Sorry I am a Naim sheep ; ) although someone with a streaming system I never ever heard of suggested the Chord Indigo (but Naim have no streaming cable so that doesn't count). Oh he is in the process of going chord music but his system is circa £50k.

The way I see it all these add ons are working to outtanding effect, but in reality they are just showing how damn good the Nova is (app excluded).

I have unplugged my USB I regard that as inferior now, as the Indigo is resolving so much unheard detail, but most of all its so musical.

i have perhaps not been clear:  i think that your choice for chord indigo ethernet is good, if you want to maximize your nova and not add boxes. You have, with the fiber bridge and cisco and indigo, a full optimized nova.   

I just pointed that chord music would be too much.....

You said you unplugged your usb, so how you listen to hirez now? 

No agree Chord Music is crazy with a Nova, BUT the Indigo has got me VERY interested, though I will try and avoid as I think I would buy it.

All Tidal now, no HiRes USB (Just bought another 128Gb). But you my friend are you using the Vodka from your Serve to NDS, that must be sweet.

Is the Nova a stop gap to something else. £3800 for a Chord Music streaming cable seems a tad excessive just to listen to Tidal ?

Just curious.

I've considered this elsewhere but naturally the actual upgrades for the Nova are limited.

Pretty much:

1 - External power amp (speakers/speaker cable too).

2 - Powerline

3 - 'Streaming cable' or other good quality interconnects

4 - Equipment support

5 - Room!

The beauty of most of these are that they would be transferable if the Nova was replaced, so while I might in hindsight have preferred one of the classic higher end streamers, they or their replacements may be what I'd aspire to, but the other elements may be cheaper in terms of outlay but could be used if/when the Nova was upgraded.

Not sure I'd pay £3,800 for the Chord Music but I think I might stretch to several hundred pounds or more if a 'streaming cable' brought worthwhile improvements - I don't see it that much differently to adding external PSUs etc (when they were a bit more affordable!)

Good man join the bonkers club when Mr Rooster, Chrissy and CHARLESPHOTO advised I thought for a punt with Prime I could test and return.

I would advise the fibre bridge first, if you like that try the ifi and that cannot be returned.

You need 2 x ifi power supplies 5V, TP link 

Two of these

TP-Link MC110CS 10/100Mbps Single-Mode Media Converter https://www.amazon.co.uk/dp/B0...cp_apa_12XHAb2SQ21DT

One of these

Tripp Lite Duplex Multimode 62.5/125 Fiber Patch Cable (SC/SC), 3.05 m (N306-010) https://www.amazon.co.uk/dp/B0...cp_apa_K3XHAbJ5Z2576

yes i use now the vodka with the serve, also between the cisco and first tp link. The meicord opal between the router and cisco, and the wonderful audioquest diamond (0,75m) between the last tp link and the nds.  My tp links are on hdplex and uptone linear ps....

the audioquest diamond is different from the vodka, more natural, refined and fluent, a big step .  The advantage is the possibility of 0,75 m vs the minimum 1m for the indigo....

Just one thought : if you stream hirez from nas, the sound will be better than tidal streaming....

I have just put a Vodka between Cisco switch and Nova, is there a burn in period? It is replacing a Melco, much less expensive....not really hearing an difference, glad it’s own loan.

Chord Indigo aray Ethernet cable is excellent! That is all I will say !  Glad you found that out too!

GAZZA - Assuming it's demo loan that's what i did, if so it should be burned it.

I personally I did not like the Vodka, but I did hear a change. If it's no good for you it's no good and stick to the Melco.

I had the AQ vodka streaming Ethernet cable and the Chord Indigo aray killed it. Significantly better !

Well I will persevere as this is new addition for dealer in terms of cables and has only just arrived. But having tried a true audio signal cable from my Core to Nova which was a Spdif digital which was very special.....I need to check their ethernet offering out as well. Plus I need to get the wife to give a second pair of ears.

GAZZA - the Vodka compared to my Chord C Stream was very noticeable, but for me not to my liking. But kudos for trying.

Oh on the WAF front she loved it, totally singing along saying so much more life like, until I told her the cost.

everybody don’t like the vodka, more to drink perhaps.  i heard there is 100 hours burn also.

I though vodka was more flammable than that!

Posted on: 16 February 2018 by French Rooster

yes, typo error, 1 second to burn in. well done Huge!

Posted on: 18 February 2018 by Obsydian

Indigo burning in well it seems to just get better, bass is tightening up, more detail - but most important of all I can't wait to listen to it and every opportunity I put in on. So listening had trebled.

Sadly artwork freezes are more frequent, wonder if Naim will blame the Chord cable.

ALLEYCAT - did you try the fibre bridge?

GAZZA - Any update on the Vodka?

Posted on: 18 February 2018 by Gazza

Update on the Vodka is that I had to get the girls in this afternoon to make sure I was not imagining things.....

The Vodka at first sounded brighter, but after a few days.... it is still different to my Melco link from Cisco to Nova. But time and time again A-B-A, or any combination, my current Melco sounds better to the girls.To me it’s very marginal......but the Melco is much cheaper. I listened to a True audio signal co. Equivalent to Naim dc1, was Impressed, so now waiting for a set of their ethernet cables.

Posted on: 18 February 2018 by French Rooster

i am burning too the vodka, maybe 40 hours now and comparing from time to time with the meicord opal( between router and switch):  the vodka has more body and a little better bass, but a bit heavy....the opal is still a bit nicer and lively, more freedom of music and better balance.   I will wait a bit more for vodka burning, but feel it won’t really change anymore...and i will certainly sell it.

Posted on: 18 February 2018 by Obsydian

GAZZA - Yes be good to hear other brands compaisons. I read up about melco but opted for Supra early on.

For sure the A-B-A should be clear and likeable or not worth it.

FRENCH ROOSTER - Yes the break in is surprising for a cable that most say makes no difference. The bass increase and quality is pretty amazing.

Gosh I even started listening to Antonio Forcione, with the Indigo you really hear every little nuance and can admire his musical skill.

I'm running a Meicord Opal myself with the UQ in the office. Very musical and full sound. Upstairs using a Ghent Audio JSSG cable. Very neutral and solidly built with the option of a 45 degree connecter which is great for my microrendu that's using a hard USPCB connection directly into the rear of the V1. For $80 (or less) it would interesting for those of you with bigger wallets to compare it to AQ or Opal or Chord offerings. I've had Cinnamon cables in the system and found them detailed but too polite and anemic compared to Opal, Ghent, or just plain Amazon Teragrand.
