Is my CDX2 headed to AVOptions?

System is purring, but every now and then, the CD scratches, a high pictch sound.

Naturally, I clean and shine the CD, and investigate for scratches.

Some CDs, not all, usually happens after an hour or more of continuous play.

Just purchased a Brand new CD, Patricia Barbara, Blue Cafe.

Nice CD, no high pitched squeals for the first hour, then they came, 3 or 4 during the performance.

 Is that the symptoms of an faulty laser?

Cdx2 MK I (2008) picked it up 2nd hand January 2015.

Check for a loose SNAIC somewhere in the system.  Power down first though, or at least disconnect the speaker leads.

Thanks Richard, I will follow through on the above.

Listening this very moment, it appears to happen on the slower cuts, timing issues. Out of the 10 or 11 tracks, I can guess the 2 tracks where the skipping will crop up. 

@ James & Yet:

I thinking the source, the player, the CD.

And yes it is the later MK I, with the 1202 VAM.

The plastic puck, no more rubber o rings version.

My model is the 2008, right before the 2009 MK II.

Thanks again, I hope it's a matter of loose connections, I dread the following:

"During service all CD players receive full diagnostic testing, cleaning inside and out

including the critical CD tray area, all around inspection, laser current setting, firmware

updates, final test by listening

$1425 USD

Vs

C20: CDX2 - CD mechanism replacement (for VAM 1202 mech version *)

$735 USD"

The Forum at it's Best!

Thanks!

Is it a puck with rubbers or the later one?

Yeah, if it's the puck with the rubbers, then the squeal is most likely the CD slipping. I used to get this occasionally on my original CDX2. Easily fixed by GENTLY teasing out the rubbers a little with a tooth pick. All squealing stopped and I felt the SQ improved a little as well.

Allante says it's an all plastic puck, a few posts up.

Yes, but I did take Richard's Advice, and disconnect the Sniacs and powered the System down. Upon careful inspection, I did notice the 5 pin din connection at the HCDR was not the most pristine. The rubber was not fitted firmly against the metal din connection, wasn't much I could do straighten it out and unplugged the digital airport express. The other three 4 pin din connectors were pristine, and to boot I would imagine they only transfer power, whereas the 270 degree 5 pin transfers power and signal.

Question:

Does Chord manufacture a replacement, 5 pin 270 degree din for Naim's Snaic?

My 5 pin 180 degree Lavender is pristine, just purchased it brand new, January 2015.

Range:

Music

 Sarum

Signature

 Shawline

Clearwater

Of course, Music would be out of the question!

Signature or Sarum which could be matched at the source down the road.

I might get lucky, doing some intinst listening this very moment, and no skips yet!

Who knows, digital interference with airport express, or faulty Sniac!

Fingers crossed.

I've no idea. Would it not be simpler to either get your existing Naim cable repaired or get a new one from your Naim dealer?

C.

Yes Chris, but you know how we're, always trying to improve are System.

Music, I think not.

SL, I think not.

But if I could find someone upgrading, to the aforementioned, I would be more than happy to give it a go!

But more than likely, I will be replacing that Snaic, if that is the case!

And you are correct, that is the route!

1st replacement of Sniac

2nd choice between $1400 complete service and $700 mechanism replacement.

 BTW it just skipped on track 10, oh no!

Allante93!

I have read the thread twice and I am confused.

If the squeal is coming from the CD player itself and not from the loudspeakers, then it's a mechanical issue with the CDX2 and won't be anything to do with the condition of the interconnects. A laser failing isn't going to give you squeals and I think it is more likely to be the puck slipping, as Simon says.  If you are getting track skipping and jumping, especially if this isn't consistently associated with the same place on a CD, then this could still be the puck slipping but otherwise would suggest a fault with the CD transport mechanism.

If the squeal is coming from the speakers, then this might well be an interconnect problem and if it only occurs when you play CDs then the CD interconnect is the likely cause. You could buy a cheap din to din interconnect and see whether the problem goes away, before spending lots of money on a high end interconnect that you may not need.

if the squeal is coming from the loudspeakers and you are getting occasional track skips, then you probably have to look at both of the above possibilities because you probably have at least two unrelated faults.

Hi Dave, I'll give it another go.

Perhaps squeal wasn't the best word, but timing issues, off pace, skips, like an LP.

So yes coming from the Speakers. Richard Dane suggested I Power System down, and check connections.

So far good, you and Richard are on the same page. The Lavender was purchased in January of 2015, and in pristine condition.

Now the 5 pin 270 degree Snaic, which deals with power and signal, is not pristine, a little loose around metal din at HCDR.

Programmed the Cdx2 for 8 tracks, I would say, 3 or 4 incidents out of 4 rounds, not bad, but you know how we strive for perfection.

So the cheap source din is probably eliminated with the pristine Lavender.

And Chris and you are correct, repair or replace the Snaic for starters. Just entertaining the thought of Chord Signature TA source IC, coupled with Chord Signature TA Snaic.

But that's down the road !

Remember, I'm an Active fan, still reminiscing the fond days of Linn's full blown Aktiv Briks.

My System

So you gentleman are correct, that $700 on posh cables, will more than likely be dedicated towards:

SCDR & SNAXO

But yes Dave, Repair Cheap Snaic, before dishing out $1400 for Cdx2 1202 VAM overhaul.

Or for that matter, $700 for CD mechanism replacement.

 Thanks to all for your concern.

 I will post once I've repaired or replaced my Snaic.

In the meantime, check out Patricia Barbara Blue Cafe, track 2, WOW!!!!

Remember, this hobby of ours, is relevant to one's listening experiences.

Ok, now I understand why you have three (at the moment, passive) NAP250.2s. Still reckon you could use an XPS though. An opinion only, we've all got them. Looking forward to hearing that your Snaic 5 is repaired or you have a new one, and harmony is restored in your NaimWorld.

Haven't got around to getting my Snaic repaired, skipping isn't occurring as often, since I took Richard's Advice.

However, I was considering replacing it with an brand new Chord Chorus Reference Snaic.

Not to killing expensive, brand New, but not in original packaging. ( EBay UK )

Are these legit?

Built quality looks good, and of course, suppose to be a substantial improvement over standard Naim Snaic.

Searching the Forum, I've come across some conflicting information.

5 pin Din Lavender 180 degree signal only

5 pin Din Snaic 270 degree sig. & power

 Question:

Is the latter a 270 or 240 degree configuration?

Thanks in advance!

Allante93!

 

 

Allante,

I'm pleased you seem to have nailed down the source of the squeaking - when it comes through the speakers, a poor connection or damaged SNAIC is usually the cause.

Stick with the legitimate Naim SNAIC please. Discussion of any 3rd party "SNAICs" is outside of forum AUP and hence not allowed.

My Bad!

I thought Chord was ok!

 Chord Music

Chord Sarum SA

Chord Signature

Chord Chorus Reference

 Sorry! 

Got it Third-party "Snaics!"

Just considering, as Members has pointed out, best option is to get Snaic repaired.

However, is the 5 pin Naim Snaic a 270 or 240 configuration?

Once Again Thanks Richard!

@ Richard:

Is it ok to customize the length of Lavender and Snaics?

In the process of having the 5 pin din 240 degree Snaic repaired, thinking of having the length shortened.

To an nice Arch, not touching any other wires.

Thanks in Advance!

Allante93!

 

David Hendon posted:

Going right off piste here, I do agree with Richard, although I don't have a PhD in Zoology, there is no SQ advantage in shortening it and I also agree that shortening kills it's resale value. So if it were me, I would follow Richsrd's advice...

David

Well, of course, I will take Me Richard Dane's advice, but listen to what he said.

No Advantage in shorting the wire:

No Advantage in sound, but active fans are always is thinking along the lines of wire management.

But more important there is a disadvantage, who wants poorer performance!

So at the end of the day, I left institutions for Friend & 30 year Linn dealer to perform the operation, keeping the same length.

USA, Authorized  Naim dealer are far and few.

No matter what, I will be in the market for that 2nd hand Snake/Snaic.

 I did see some brand new ones on EBay, Naim original with packaging, but ofcourse, I would prefer used original.

 Why, two Snakes needed for SCDR/282.

Must A-B HCDR with SCDR!

Cdx2/282/HCDR/3 x 250.2/Briks

That's how it's done!

Thanks gentleman, that closes this one out!

Allante93!

 

 

 

Well,  I've been busy, had to save up for an second Snake to accompany my soon to be SCDR.

Just purchased it last night, Original Naim Snaic 5 pin 240 degree din, the same one used with the 552 when accompanied with the Full Loom.

 Not cheap, 120 pounds + shipping, but when you get right down to it, I guess the Naim's Snaic is an Integral part of the Naim Sound!

Next stop SCDR!

Cdx2/282/HCDR/3 x 250.2/Briks

Thanks Richard, Original Naim Snaic with original packaging is key, for resale value.

Allante93!

Once Again the Forum is a wealth of knowledge, looked up some passed post, and came up with the following. Makes sense to me.
Cdx2 2008 is still skipping with repaired Snaic.

“Never heard of a CDP recap either....!??

CDP's don't  normally need to be recapped, especially a 2007.  
Disc skipping could be as simple as a dirty laser,  has that been cleaned ???,  if not do that 1st & only that.  

SIMON-IN-SUFFOLK MEMBER

Unless there is a fault, the capacitors will be fine, and if on the way out I can't really see why the transport would skip. If its definitely not the puck. Acid test pull the tray out with the CD spinning, grab the puck and does the disc stop solid with all discs? If it slides a little then it might be puck..
But it does sound like transport,
(assuming lens is not dusty as Mike says) but you are unlucky for it to have failed so soon.
Simon”

I think I will take Mike’s Advice before dropping $700 with Service and Replacement!

After reading the former post, I thought I would try one more elimination test!

Just purchased Ray Charles brand new CD, and it was skipping, more apparent when over time, and slower cuts. Wishful thinking, and hoping it's  just a simple dirty laser, I decided to use the same CD ripped and played through the same system!

Cdx2>282>HCDR>3x250.2>Briks

MM>Airport Extreme>Airport Express> 282……. taking the Cdx2 out of the equation.

So far no skipping!

That should confirm it's the CDP.

Hopefully just an dirty laser.

Now back to local Linn Dealer, you lucky guys, Authorized Naim Dealers in abundance. The tech is Top notch, I’m quite sure, he should be able to handle that small task!

I will post the results later.

Meanwhile, the only source is wireless MM, and you know what, Its not Bad, convenience at its best!

Endless Playlist Over 1500 tunes, all controlled from my Android cell phone, while laying in Bed!

But the serious listener can tell the difference, The Cdx2 is more dynamic, for lack of words. Perhaps greater depth of field, or perhaps I’m just regurgitating hi fi jargon!

But so far, as I’m pecking away on these keys no Skipping!

Thanks Mike, and Simon!

@ Simon, I tried your test the plastic puck stoped the spinning disk, just as you pointed out!

Out!

Enjoy the Music, the Why!

Allante93!

From Trump Land! The Donald, Wow!

 

Thanks guys for leading me in the right direction! 

A.     The Sniac was not damaged, but needed an spare anyhow, for the soon to come SCDR/282

B.     $40 isn't much to have the Cdx2 Cleaned, by blowing it out, and cleaning with lens cloth by Linn Dealer but.....

C.     Cheap $2 disc cleaner, probably not a good ideal, Checked with Philips, a nice young lady from Canada did a little research,               C.     and suggested Philips SVC2330/27. She looked in her system and found Naim CDP's, of course I questioned her!   

 

I thought this would be an logical route, before shipping the Cdx2 to have her Cleaned. Besides nice disc to have around cleaning the MM Superdrive, which is playing Ray Charles this very minute without skipping. 

Hopefully just a dirty optical Laser lens, otherwise big bucks, Naim Repair facility, or AVoptions! 

On a closing note, was the laser optical lenses incorporated in the CD555 & CDX2, manufactured by Philips????

If I'm not on point, any other suggestions appreciated!

Well going on three months, and I tried everything, Philips cleaning disc, air blowing, repaired Snaic, and nothing worked! Sooooo! 

Is my Cdx2 headed to Avoptions ?  No, they were backed up 2 months, and suggested I ship it to Audio Plus. Worked out fine, those guys are great, don't like talking on the phone, but good people! 

She is scheduled to be shipped first thing in the morning! 

What did I learn? 

A. If you have a CDP, chances are Philips or Sony, manufactured the Optical laser lens.

B. The VAM 1250 Replacement cost, is nearly double that of the VAM 1202.

C. CD players will eventually break down, Mechanisms! 

So, if you happen to be in the 2nd hand Market for an Cdx2, make sure its 2008, or better. 

Otherwise, be prepared to fork out $700 - 1K with the earlier models.

Not really expecting any improvements in SQ, she performed flawlessly. 

Just that annoying skipping/scratching, which occurred 3 - 4 times per CD! 

I will report back within a week, if I notice any improvements in SQ. 

Otherwise Out!

I think it's time to start thinking about streaming....

Yes, I have been thinking about streaming, but I really don't understand it! 

Paraphrasing Simon:

" A new paradigm, no longer just, the analog TT, and Digital CD, But the Trinity! "

The Analog TT, Digital CD, and Digital Streaming, depending on Mood, and Music! 

We are all familiar with a gentleman on this very Forum, who has happens to have two very fine front ends. In fact, both of his front ends swallows my whole system, LP 12 & CD555. Another Familiar gentle on this very Forum struts an CD555 with an S1 Pre Amp. 

Point being, I can't afford all three, but when I sold my LP 12, I knew I would be headed towards Streaming! 

Chords, Hugo, TT, and Mojo, I guess they are Dac's they are catered towards Streaming! 

Digital Downloads, that rivals, or betters the The ancient CDP. And of course the ancient and improved CDPs, that mimics, the Barbaric TTs. 

This was a good experience, being without my CDP for nearly 3 months. I got a chance to really listen to both of my Systems.  From my Computer: 

MM>Airport Extreme>Airport Express>:

A.  282/ HCDR / 3 x 250.2/ Briks

B. Emotiva Dac !  / Primare Pre 30 / Arcam P1 Mono Blocks / Vienna Acoustics Baby Grands

In short, not Bad, the convenience, can't be beat, endless personal playlist, Library consisting of over 2000 tunes, which I ripped from friends, and bought tunes for a buck off iTunes, after listening to them from internet Radio. And to boot, all of the controlled from an Android phone, while lying in Bed! 

In short, I miss my LP 12, but I don't miss the snap crackle pop, that came along with it, and I didn't  want to invest 5K to bring it up to spec. So I sold it! 

So, I don't really understand streaming, but what ever I'm doing it ain't bad, but it ain't no Cdx2 in the Living Room with the remote in hand. Missing a bit of dynamics, maybe a little bit of pace, hard to describe, but you guys know what I'm getting at.

Always happy to help

The way I think about streaming is as follows: it's a player, but rather than load a CD with digital files on it, the files are stored on a local server / drive (commonly referred to as NAS).

  • So if you think what your CDX2 does so well: you take a CD, put it on a tray, load it and pres play.
  • Now with NDX: files are on your NAS, you find what you want to play, cilick on it and pres play.

That's about it really.

Of course there is some infrastructure to be put in place, but it's neither complicated nor scary - I can 'talk you' through it in 1 email. You already have most of the required components at home anyway - it's your internet bits and bobs.

Well, 3 CDS so far, and not one skip or high pitched squeal. However, this listening session took place whilst tinkering with some Gaming Chairs, hence I was listening from the rec room.

Later tonight, for some serious listening in the Living Room!

I will report back tomorrow, if I notice any SQ improvements.
