Naim Rips -vs- Ruby Ripper Alias WAV -vs Flac!

Posted by: Mr Underhill on 17 March 2011

In auditioning the UnitiServe & NS01 I have been struck by how much better the Naim rips were than those made using my standard ripping technique, RubyRipper on Ubuntu.

Naim rips to WAV, so was the difference due to the way Naim handles a flac file?

I used flac to decompress three  of my 'flacced' albums:

Praise & Blame - Tom Jones;
The Rock Soundtrack; and
Diva - Annie Lennox.

I reripped these CDs using the UnitiServe.


In all cases playing back via US/NS01 -> nDac -> EAR864/534 -> Living Audio Auditorium II.


The WAV was easily picked for P&B and Diva. A slight edge on vocals was apparent.

Naim WAV -vs- Decompressed flac. No difference that I would be able to pick blind.



BUT:

I think this is well worth mentioning. The Naim ripping process it amazingly fast and easy. Usability is a very nice quality.

Why bother? It's all in the interest of better sound quality. Hampering the performance of an audio file that was externally sourced doesn't serve that aim at all, and, comparatively speaking, it's better to explain the differences rather than relying upon blind insistence that one rip sounds better than another.

Paul's remark hits it on the head–in the case of some releases, the differences are not nearly as large as with others. Even this notion would explode the heads of data positivists–but not of CD player engineers–so it's not likely tied to data formatting, either...(where the result should be consistent across all discs / rips).

Then again–if all CD ripping processes sounded alike, there would be no need to re-invent the wheel, right? The notion exists due to failure of the prior art, as regards audio performance.

If the audio bits in the rip are the same, then they should be served up the same and sound the same.

If the audio bits in the rips are different, then it is an absolutely objective matter which, if any, is correct.

Which is it?
Hang on ... it was Phil on the 'grassy knoll' all long .... I'm convinced that there were two streamers and that Naim is in fact a cover for organised crime with links to the Cuban mob. No wonder their cases are so heavy; they use them to weigh down the bodies. Yes it's all clear to me now .... I bet it's not black aluminium but lead to absorb all the radiation ...TJ is probably an alien .......ahhhh

@likesmusic - get a grip this is getting ridiculous. Next you will have us believing Naim is being run by communists.

It is indeed getting ridiculous Tog.

Neither Naim nor it's distributor are denying that a UnitiServe rips exactly the same audio bits as dBpoweramp.

But they are both saying that these rips sound different.

Therefore the UnitiServe must serve up different bits across a network.

Therefore the UnitiServe cannot be extracting the audio from a dBpoweramp rip correctly, or serving it correctly.

Ridiculous indeed. Or broken.

So, if you've ripped thousands of cds with EAC, you're not going to want a UnitiServe then, as it makes them sound harsh? 

Was this difference when the files were served across a network, or played straight through s/pdif into a DAC?
Did you even read my post properly???????????????????

How can I have read it properly when it wasn't being read by a UnitiServe?

I do not understand what a 3rd-party ripping service has to do with this conversation.  I have already stated multiple times that I am willing to believe that Naim can deliver improved sound quality on playback.   The reason I have not demo'ed the UnitiServe isn't philosophical -- it is that I do not want to expend the effort of re-ripping.   Others may, but I don't.

And I disagree with your contention that this is as much about the computer business as audio–it's too naïve and data-centric an approach, and has been heartily re-buffed by many audio manufacturers over the last two decades or so–not just Naim, nor just with Compact Disc.

Are you disagreeing that the PCM data in Naim and non-Naim rips is the same?  Yes, this is a data-centric view, but hardly naïve.  Naïve would be a blind acceptance that there was some magic in all of this.   Again, have already stated that I am willing to accept that the Naim software and hardware can deliver better sound quality, even with the same PCM data.   The argument here is why re-ripping is the only way to get there when, at least on the surface, it would appear that an import facility would make good sense.

This is not being "objectivist".  This is not the old bits-are-bits argument. This is simply a constructive suggestion for making a Naim product easier to buy into.   If it was a stupid suggestion that showed a complete lack of understanding for the unique demands of software development in the audio world (as opposed to the rest of the software development world), then I apologize.   Geez, twenty-five years ago when I was modifying kernel code to port SVR3 UNIX to a new supercomputer architecture, things weren't even this complicated!


It's not good enough that an audio company would take the time to find the best-sounding ripping algorithm for their servers–why is that?

You are acting like I have said something bad about the product.  I don't get it.

Is this a skepticism based on an objectivist view of data? Or is it a knee-jerk reaction to the notion that, in the audio world, there are some things that require more than a superficial level of understanding from an engineering standpoint? Or, even more challenging–that there are parameters relating to these processes that shouldn't have any effect, but do nonetheless?

Sigh.  Ok, now I do get it.  Importing would be too hard to implement.   No problem.  It was a stupid suggestion.   Sorry, will try to not make such such stupid suggestions in the future.

Taking that skepticism further–how do you ultimately know that AccurateRIP is in fact correct? Statistically normal, perhaps–but correct?

You asked a question -- how do we do this?   I simply tossed out an idea.  I never claimed it was a great idea, or even doable.  It was a simple suggestion that you have, for whatever reasons, decided to overreact to.

Naim took a stand on ripping quality, developed a server, developed a streamer, and developed the applications to control them. If you feel that this exercise prohibits you from migrating to a Naim server based on objectivist data principles or other forms of orthodoxy, then maybe you're missing the point–to provide the best possible sound quality (from data acquisition to conversion to analogue).

I do not disagree on any "objectivist data principles".  I am not that complex.    The obstacle for me is the amount of time and effort to re-rip.   If there are insurmountable technical challenges to taking the identical PCM data from non-Naim rips and putting a Naim header and trailer around them, then so be it.

Also, I never said that controlling the process from rip to playback was bad idea.  I am not missing the point.  I was simply suggesting that having an alternative data acquisition strategy might be a good thing for Naim to consider.


Much of this would be obvious during a demo–but, inasmuch as your retailer lives halfway across the country, this is not an easy or obvious exercise, and I suspect you've probably never had the opportunity to do the demo.

Wow, what a surprising for you to say. 

Are you referring to the same remote dealer who took me from not knowing who Naim was to a DAC/555PS/252/SC/300/Superline, all Poweline'd and Hiline'd, in a little over two years?  The same dealer who has invested a countless number of hours into the business relationship, and without whom I would have zero interest in Naim?   You mean that guy?  
Yeah, you're right, he doesn't live next door.   But that doesn't mean that the option for me to home demo an HDX or UnitiServe hasn't always been there -- a phone call or email away.  By the way, I would rather do business with the best, not the closet Naim representation.   In my opinion (and in this case, Dave, my opinion really *is* the only one that counts), I have done exactly that.   We can have a discussion about local options if you want, but I doubt you would find that to be a very pleasant conversation.

This all started with me saying that I thought that an import facility would help make the UnitiServe a better product, and it ends with this?    You obviously have no clue why I am financially and emotionally invested in Naim.   How disappointing!

Glen, don't take it personally–we have always encouraged retailer demos and have worked towards insuring, over the last two years, that Naim is represented in as many retail locations in the US as can be supported with proper demonstration facilities and qualified staff.

If your existing relationship with the local retailer was unpleasant–let me know. We can fix the situation, as someone else may also be experiencing the same problem.

We've always appreciated your business, though it is important that you know that we encourage customer relationships with local retailers so that it is easier to understand and appreciate differences in performance, to make the best possible choices for your own system. This reduces the amount of support inquiries we get from customers in the US who live at a distance from the retailer who sold them their system.

This helps you, and it helps us–and it reduces the noise that often fills many of the message boards or user forums, to be replaced by experienced, nuanced posts that reflect one's actual experience within your own home (or a retailer demo). 

It's not always easy to quantify differences in performance via a message board or user forum, and I think, sometimes, that much is lost in translation. If I have offended you, I apologize–but my point remains that my own extensive computer experience takes a back seat to my ears when it comes to these things, even when my brain tells me that the result should not be so.

It's probably a safe bet that there are others here who feel the same–and we're all trying to get to the same place.

This is a very interesting and informative thread. Thanks to all of you who have contributed. It made me notice again how complicated digital audio actually is than some people assume.

Has anybody compared technically the rips of HDX with those of UServe? Temporarily, I have both of these devices now. I had heard a significant difference of their dig out through nDAC. Now, during my initial listening sessions with NDX, I hear they sound different also as UPnP servers through NDX. The difference probably lies in other factors than the rip itself, if their ripping algorithms are the same. Can we test this? How can I bit compare them myself, or send one of you some files, as long as I have both devices?
Posted on: 24 March 2011 by likesmusic
aysil, that's a great offer. If you ripped a cd that most people are likely to own, or even a Naim cd, then other people could check it out and compare it to their EAC/dbPoweramp rips if you sent them a copy

Or perhaps Simon-in-Suffolk could let you know how to check the audio bits yourself.

And why doesn't David Dever offer to email Hook a UnitiServe rip of a cd Hook has ripped so that Hook can see what merit there might be to David Devers claims? No need for anyone to travel to a dem.

If you would like to understand how I wound up working a remote dealer, I would be glad to tell you.   If you do not have my cell phone number, then you know who to get it from.

Thank you for saying that, and I do understand.  Lucky for me, my dealer has answered every question, and resolved every issue I've ever had with Naim products.

This helps you, and it helps us–and it reduces the noise that often fills many of the message boards or user forums, to be replaced by experienced, nuanced posts that reflect one's actual experience within your own home (or a retailer demo).

Also agree with you here, and no hard feelings.   Everyone agrees that auditioning is essential for judging sound quality, and that the ears are more important than the brain.   And nobody wants to hear opinions about sound quality from someone who hasn't auditioned a product!

But please note that in this particular instance, the only comment I made on the UnitiServe's sound quality was to repeat what Naim has said many times, and that is that a UnitiServe will sound best with Naim rips.   
All my other comments were based only on a desire for additional functionality only.

It's probably a safe bet that there are others here who feel the same–and we're all trying to get to the same place.

Amen.

I think that says pretty much all about this. If you want a ripper with all the serve function and dig out, unitiserve is a great product (though less so for chinese people as it cannot index nor support display of that language apparently from another thread) Judging by the rip function itself only is probably hard when compared with other alternatives.
Posted on: 26 March 2011 by Jack

aysil.......my understanding is that the ripping engine of the HDX and UnitiServe are the same so you should under normal circumstances get the same data.

 

It seems to me that part of the issue with this discussion is sometimes around the terminology. For me ripping is about getting data off the CD onto the hard disk drive in an accurate manner. It has nothing to do with playback at this point it's all about extracting the data.

 

So I think terms such as "best-sounding ripping algorithm" can be slightly misleading.......if the Naim rip and the EAC rip are the same from a PCM data perspective when wriitten to disk then there is nothing about that process that makes one sound better than the other IMO (how can it, it's just extraction). Playback is of course different.

 

I don't think Naim has claimed to be doing any sort of optimisation during playback depending on whether it's a Naim rip or other but this could equate for playback differences if they exist. I guess there could be all sorts of other factors affecting playback and hence why Naim recommend a complete Naim solution for optimum SQ.

As am I - IMHO, the SQ is just as good no matter which ripper you use.  

That is interesting.  I am known to be cloth eared. I make no claims to being one of the talented golden eared types, yet I listened yesterday to the first rips of some 80's CD's done via my (yet to be run-in) UnityServe SSD and I thought the SQ was outstanding.  All my doubts about spending over £2,000 were dissolved in a sea of joy.  Words cannot express how good my system sounded.

 

All previous rips into iTunes (using ALAC and my iMac) and then copied onto the NAS, seemed tame in comparison.

 

Just my thoughts, others may disagree.

I think the psychological impact of spending £2000 on a UnitiServe can be blamed here - me a bottle of Chablis has a similar effect and somewhat cheaper. :-)

We know where you stand on the UnitiServe's price, Tog, but that's not the cause of the psychological impact. It's the musical performance that's to blame. Unfortunately it's just consistently engaging and deeply insightful. Mine is now into its fifth month and I'm still waiting for it to stumble so I can point an accusing finger and proclaim 'Ha !, it's just an overpriced PC !' and then run out and buy a Vortexbox or something.

You might be correct.  But my ears say you are wrong.  So who am I to believe, you or my ears? 

One thing I have noticed is the UnityServe, certainly the SSD model does not do a simple iTunes-type rip.  In iTunes as soon as it is finished, there is the ripped album.

With my UnityServe, despite taking rather longer to actually do the rip, even after the CD has been ejected and packed away, I see data continues to flow up to the NAS.  As long as another 10 minutes.  Whatever it is doing during this time must be something helpful, else why bother?

Obviously there is no sign of the album on the DTC until this data flow ceases.

BTW, I only noticed this effect tonight.  So my comments regarding SQ were not some subliminal encouragement to believe it must be better because it takes so long to complete.

Richard, Buffering from SSD and defer transfer to the nas is one explanation to it. It all depends on how you look at it. But looking for a reason is not what we are after. I agree with you. Satisfying your ear is most important! So thanks for sharing your joy here!

@Jan You obviously missed the smiley on the last post - I'm often accused of being flippant but sometimes I can't resist pulling people's legs and you really shouldn't take it to heart. By the way on UPnP with flac on a blind test using none US ripped files VB and US sound exactly the same. :-) Tog

The album is copied to its final destination after ripping–this protects against data errors caused by network faults (i.e., taking the Ethernet cable out of the rear of the server).

Another interesting comparison is, if an album has both a vinyl and cd version, can a rip to 24/192 or 24/96 sound better than the cd rip?
Posted on: 28 March 2011 by jon h

it would be interesting to compare a naim rip to a rip done on another device that uses the digifi platform.

 

"Naim’s HDX is powered by the DigiFiTM platform; leading edge software technology licensed from DigiFi Ltd of London"

 

from the naim_cd_ripping_engine.pdf file

 

And it would be useful if there was a source for the WAV Compare application shown in that pdf file too.

I have this situation with about 60 Zappa albums (24/96).  I listen to both often.  The 24/96 vinyl transfers are great, although you cant really A/B compare to the CDs.  They are simply different.  In some cases I prefer one over the other, but I dont think it has anything to do with the resolution.
