ND555 Impressions

Gandalf_fi posted:

Am I the only one here who was not impressed by ND555 demo vs. home and NDS? This time with 252/300/Focal. I have totally different, more revialing system which affects but my expectation was that I should be impressed anyway with that more modest system. I definitely need to do a home demo because of based on this NDS is not broken and sounds pretty close to ND555.

What happened

  • Rythm: sounded exactly same, no difference
  • Bass: was maybe a bit more wider at the low end but difficult to say because of speakers
  • Dynamics: difficult to say, so much system dependent
  • Openess/clarity: no difference, so much system dependent
  • Voice: not fair to compare because of Focal is not the best one

So, please help me a bit if you have some thoughts why to replace NDS?

No comparison in the ND555 vs NDS. ND555 is noticeably better. Not sure why you did not hear much difference . 

Interesting hobby this. My thoughts on a couple of recent themes. First I prefer single supply on the ND 555. I have no experience with Melco but hear the difference with a rip of a CD via the core versus a previously ripped file from the serv or in respect of a file of undetirminable providence. I had noticed this previously with my NDS and frankly it came as a bit of a surprise. I was intrigued with Darke Bears experience with hard wiring the iPad to Ethernet and tried this last night. I felt their were pros and cons but accept that this could in part be how I configured the connections. I then tried listening with the wi fi on the iPad turned off. Ie select album to play then turn wifi off on the iPad. Again I was surprised at what I heard. Practically though doing that ie turning wi fi on and off as required is a whole lot less hasell than going through the whole registration set up thing when using an Ethernet connection. As they say everything makes a difference but the challenge is in trying to fiqure out whether it’s better or worse

The problem of deciding in which file formats (the emphasis is on the plural!) to store music has been discussed ad infinitum in this forum and such discussions are typically not very fruitful. Just store the files for replay in whatever format you please but do yourself a favour and rip, download, edit, backup and retrieve .flac files!

But was there not earlier advice offered to Richieroo to go ahead and rip in wav?

My head is beginning to hurt ....

Sure as he seemed to be comfortable with editing .wav files. If one has a good tool to edit .wav rips and one does not care about storage space and data transfer time than .wav is certainly fine.

As a matter of fact, however, there are more and better tools for managing .flac files than there are tools for managing .wav or .aif files. Also, .flac files are smaller. Thus, my generic advice is to use .flac for ripping, editing, securing, etc.

On another thread: I had a look at the Melco D100 and it looks like a very nice reader. I would have no concern connecting it to my laptop for ripping. It is hopefully faster and certainly heavier and much nicer than the typical 50$ plastic reader. But I would not want the rips to go directly into an N1 or into any other dedicated music server. That does not make any sense to me: transfering the data to the music server is the very last step of my workflow, not the first one! 

Thanks Gazza.........I did not get home until late last night........I briefly looked at one burndy..and thought oh .... no real obvious marker.......I did notice a green section through the mesh outer binding.......... and did wonder ....... I imagine the other will correspondingly be red. Thanks for your advice ....great.............I will power her up at the weekend............

ok,,,,maybe I'm some sort of deaf...but I ripped one title via db Power and XLD and in wav, flac, aiff....can not hear a difference... Concerning Melco- if you plan to run Roon as well, you should have a look at Innuos. It can run Roon server and acts as an endpoint!

If you don't hear the difference, that's fine for you. Quite a number of people perceive a difference between flac direct and wav, I am one of them.

Hi quick question........have taken delivery of my ND555 yipee........ and it comes with new burndies............are these directional?.........I seem to remember the NDS burndies had a marker at one end........can anyone advise........

Check out the handy Quick Start Guide that came in the box. In your excitement you may have overlooked it!  It shows that the markers go at the ND555 end, and tells you which Burndy goes where.

Installing Roon Server on the Melco isn't a good idea at all, I'm sorry to say.

Roon Server is quite a piece of sofware and needs a lot of computing and therefore generates a lot of "electronic noise".

Roon Server (or Roon Rock) should be kept away from the HiFi system and, ideally, should feed the ND555 through a good WiFi (avoiding galvanic connection to the potentially noisy Ethernet network).

Roon Labs provides well written and extended documentation on how to setup your Roon environment with sound quality in mind.

From what your own ears tell you, the answer is self evident. Don't buy the ND555.

If only my home demo had come up with that result. I'd still have the money and be perfectly happy with my choice.

For the sake of balance, I will mention that:

If you have storage space that is so limited that you will have difficulty accommodating  WAV files in preference to FLAC files, you have got much bigger problems than tagging. The fundamentals need rethinking. Storage is cheap.  Storage capacity is not a limiting consideration. If your hardware will only accommodate a HDD up to a certain capacity, and/or is not user expandable, get better hardware because yours is not fit for purpose. If you can't hear a difference between formats then you can do whatever you prefer. If you can hear a difference, it is ridiculous to compromise for the sake of storage space.

WAVs are easy to tag. dBpoweramp is an excellent tool for doing this and way more besides. There are plenty of alternatives. It seemed easy to feed CDs into my HDX and let Naim's bit perfect ripping system take care of all the hard work. This was an illusion. There is nothing difficult or unique about obtaining a bit perfect rip and verifying that you have done so. It costs tens of pounds to achieve this with high confidence, not thousands of pounds. Furthermore, Naim rippers do not tag WAVs correctly. In fact, they don't tag them at all.

Well that shouldn’t be a problem, as Roon will not run on a Melco as far as I’m aware.

No, could not compare NDS vs. ND555 in the demo, just ND555 + go home and listen same tracks with NDS. Expected some kind of WOW with ND555 but it did not happen.

I have no experience with Melco but hear the difference with a rip of a CD via the core versus a previously ripped file from the serv or in respect of a file of undetirminable providence. I had noticed this previously with my NDS and frankly it came as a bit of a surprise.

The ND555 sounds very different over the first several weeks of its life and I'd try the two supplies after it had been run-in for over a month if you had negative results before ruling it out ahead. There was another poster who also said they had preferred a single supply and then only later found that two supplies was a lot better. Two supplies makes the ND555 more revealing of both music and run-in artifacts and the latter can shout at you more unpleasantly. Always personal, but my demo was conclusive that in my system the ND555 was significantly better with two supplies in terms of detail, stability and more extended and better articulated bass and HF - not jut the HiFi sound aspects but I preferred it musically. It is fine with one supply but not worse with two IMO.

The Ripping - I've said all I can at this point and essentially make sure you have that optimal for you and check it out yourself.

On the WiFi use for the control App - I find the noise-floor lower when the WiFi is off and hear an obvious (to me) wall off noise drop from the sound-stage when I turn-off the house WiFi and get better depth info and immersion into the music and it just feels more relaxing to listen to. Why - well removing a wide-band noise transmitter may be part of the answer - perhaps?

However as you also notice the present Naim App has a problem with operating without WiFi and goes into a pointless sulk telling you that you have no WiFi - but still works as you have a wired-LAN but need to re-register. It takes 20 secs to do and I've done it so many times I'm used to it as I refuse to be bullied to conform when I want it otherwise - hopefully the next Beta App when available will sort that out - I shall see.

WiFi is convenient but I find I don't really need it a lot in my house as it is all Ethernet wired so I have LAN points everywhere to use - so I use what gives me best sound. Different systems may sound very different with respect to interactions with RF signals and WiFi - mine is a large cross-section for anything to make ingress at RF frequencies and the noise floor is where I'd first expect I may hear that if present. Plus I was curious as to the effect of removing a local transmitter would have - people assume it is all fine, perhaps it is as it is very convenient, but is there any down-side.

I grabbed a Core when I upgraded to a Nova and re-ripped my collection - previously ripped and streamed from a Mac. I’ve compared both rips through the Nova and there is a clear improvement with the Core. I have a degree in Civil Engineering and oddly enough a trained Yoga teacher too, so I go with the Yoga approach that if you experience the difference through your own discernment, then it is real.

I found the same when I ripped some discs on the core. I too was using a mac, with xld and dbpoweramp to rip (then streamed from a synology nas). The core was best, followed by dbpoweramp then a mile behind was xld. To my ears, and in my system the difference was quite easily noticeable.

Mr Happy- if you move a ripped file to Core, does it sound different via internal rip?

Hi, I returned the core quite a while ago now. The comparison of the 3 different rips was done on my nas (synology 218play), and also at a friends house on his nas. We both have revealing systems and could both clearly hear differences. I found xld to be quite poor compared with dbpoweramp. Dbpoweramp was very good but the core sounded best to me.

Thanks for reply! Just checked my CD vs download ratio...I will not invest in Core, bought more music from qobuz etc. than CDs.
