Fleetwood Mac: What’s the Difference Between These Two Compact Discs?

Wednesday, August 26th, 2026
Lets start this by saying….As a “HiFi snob”! With lots of audio equipment!
Apart from the obvious difference — one has a black spine and the other has a clear spine — what’s the difference between these two compact discs?That was the question that started this little investigation.At first glance, both CDs contain the same Fleetwood Mac album. One is an early West German Target CD and the other is the 2004 remastered and expanded edition.But are the original album tracks actually the same?Does the 2004 version simply contain the same digital master at a higher volume?Or did the mastering change?I decided to find out.

The Two CDs

The 1994 West German Target CD

The first CD is the West German Target pressing.

The most immediately noticeable feature is the black spine, along with the distinctive Target-style disc design associated with these early CD releases.

The disc contains the original 11-track album:

    1. Monday Morning
    2. Warm Ways
    3. Blue Letter
    4. Rhiannon
    5. Over My Head
  1. Crystal
  2. Say You Love Me
  3. Landslide
  4. World Turning
  5. Sugar Daddy
  6. I’m So Afraid

The disc was manufactured in West Germany and is one of the early Target-style compact discs associated with the original CD era.

There is something rather special about these early Target CDs. They belong to the first generation of commercially produced CDs and have become collectible in their own right.

But I wasn’t interested in the Target CD simply because it looks good.

I wanted to know how it sounds.

The 2004 Edition

The second disc is the 2004 remastered and expanded edition.

And immediately there is another obvious physical difference.

The spine is clear rather than black.

But the differences go much further than that.

The 2004 edition contains 16 tracks, rather than the original 11.

The five additional recordings are:

  1. Jam, No. 2
  2. Say You Love Me
  3. Rhiannon (Will You Ever Win)
  4. Over My Head
  5. Blue Letter

So before we even listen to the two CDs, we already know that the 2004 edition is more than a simple reissue.

It is an expanded and remastered edition.

But what happened to the original 11 tracks?

Let’s Rip the CDs

Rather than relying on my ears alone, I wanted to make this as objective as possible.

Both CDs were ripped using Exact Audio Copy (EAC), using secure extraction, and saved as lossless FLAC files.

The EAC results were then checked against AccurateRip and the CUETools Database.

The results were excellent.

1994 West German Target

All 11 tracks were reported as accurately ripped.

No errors occurred.

2004 Edition

All 16 tracks were also reported as accurately ripped.

No errors occurred.

The 2004 tracks had an AccurateRip confidence of 200, providing extremely strong confirmation of the extraction.

This means we weren’t comparing two recordings made from a CD player.

We were comparing the actual digital audio data extracted from the CDs.

The First Track: Monday Morning

I started with the opening track, Monday Morning.

And this is where things immediately became interesting.

The 1994 CD has a peak level of approximately:

-2.47 dBFS

The 2004 version reaches:

-0.10 dBFS

So the 2004 version is getting extremely close to digital full scale.

But peak level alone doesn’t tell the whole story.

The average level is even more revealing.

The 1994 version measures approximately –20.6 dBFS RMS.

The 2004 version measures approximately –13.2 dBFS RMS.

That’s roughly a 7.3 dB increase in average level.

In simple terms, the 2004 version is substantially louder.

But I wanted to know whether that was the whole story.

Is the 2004 Version Simply Louder?

This was the obvious question.

If the 2004 CD was simply the 1994 mastering with the volume turned up, reducing the 2004 version by the appropriate amount should make the two recordings essentially identical.

It doesn’t.

I level-matched the two versions, removing the large difference in overall volume, and then compared them again.

There were still measurable differences.

That means the 2004 version isn’t simply the 1994 master with the volume increased.

The mastering has changed.

The Dynamic Range Difference

One of the measurements we can use to examine this is crest factor — the difference between the average level of a recording and its peaks.

A higher crest factor generally means greater separation between the average level and the peaks.

For Monday Morning:

1994: approximately 17.6 dB

2004: approximately 13.1 dB

That’s a difference of approximately 4.5 dB.

And this wasn’t unique to Monday Morning.

When all 11 tracks appearing on both CDs were analysed, 10 of the 11 tracks showed a reduction in crest factor on the 2004 version.

That is a significant pattern.

It tells us that the 2004 mastering has generally been made louder and denser.

It does not, by itself, mean that the CD is clipped. High peak levels and clipping are two different things.

The Whole Album Tells the Story

This is where the comparison becomes much more convincing.

Rather than looking at one song, I analysed all 11 tracks that appear on both CDs.

The average RMS difference across the album is approximately:

5.3 dB louder on the 2004 edition

Every single one of the 11 common tracks is louder on the 2004 CD.

The graph makes the pattern very easy to see.

The 2004 version is consistently louder across the original album.

But What About the EQ?

This was the next question.

Perhaps the 2004 mastering was simply compressed and made louder.

To test that, I removed the volume difference by level-matching the two versions.

Then I compared their frequency spectra.

And again, the results showed that the two CDs aren’t identical.

The broad album-wide differences were approximately:

Frequency range 2004 compared with 1994
20–60 Hz -1.6 dB
60–120 Hz -0.8 dB
120–250 Hz +0.7 dB
250–500 Hz +0.7 dB
500 Hz–1 kHz +1.2 dB
1–2 kHz +0.7 dB
2–4 kHz +1.2 dB
4–8 kHz +1.7 dB
8–16 kHz +1.6 dB
16–20 kHz +0.9 dB

The important point isn’t each individual number.

It’s the overall shape.

After the overall volume difference was removed, the 2004 mastering still showed less energy in the very lowest frequencies and more energy through much of the midrange and upper frequencies.

So the tonal balance has changed too.

A Picture Tells a Thousand Words

Put the two discs next to each other and the physical differences are immediately obvious.

The black spine and clear spine are only the beginning.

The artwork, disc design, catalogue information, packaging and track content all provide clues that these aren’t simply two identical CDs from different production runs.

But the really interesting difference is something you can’t see by looking at the discs.

It’s in the audio data.

Eleven Tracks, Same Conclusion

The strongest evidence comes from looking at all 11 tracks common to both editions.

Every track is louder on the 2004 CD.

Ten out of eleven have a lower crest factor.

The frequency analysis also shows a different tonal balance after level matching.

This means we can confidently say that the 2004 edition is not simply the 1994 mastering with the volume turned up.

There has been a change in the mastering.

And Then There Are the Five Bonus Tracks

The 2004 edition adds five additional recordings.

These aren’t relevant when comparing the mastering of the original 11 tracks, because there is no corresponding recording on the 1994 disc.

But they are still an important part of the comparison.

The 2004 CD therefore offers something the 1994 Target doesn’t:

additional material.

So Which One Is Better?

Now we get to the difficult question.

Which CD sounds better?

The measurements can tell us what changed.

They can’t tell us what you will personally prefer.

The 1994 West German Target

  • Lower overall mastering levels
  • Greater peak-to-average separation
  • More headroom
  • A different tonal balance
  • The original 11-track album

The 2004 Edition

  • A substantially higher average level
  • Peaks much closer to digital full scale
  • Reduced peak-to-average dynamics on most tracks
  • A different tonal balance
  • Five additional recordings

If you prefer a mastering with greater dynamic headroom and less aggressive level management, the 1994 Target is likely to be the more interesting choice.

If you prefer a louder, more forward presentation and want the bonus material, the 2004 edition has obvious advantages.

The Conclusion

So, what’s the difference between these two compact discs?

Quite a lot.

It started with something as simple as noticing that one had a black spine and the other had a clear spine.

But once the discs were ripped and analysed, the differences became much more substantial.

The 2004 edition isn’t simply the 1994 CD with the volume turned up.

Across all 11 tracks common to both editions, the 2004 version is approximately 5.3 dB louder on average.

Ten of the 11 tracks show reduced crest factor.

And after level-matching the recordings, there are still measurable differences in frequency balance.

In other words, these are different masterings.

The 1994 West German Target represents a much more conservatively mastered presentation, with greater peak-to-average separation.

The 2004 edition offers a louder, more forward mastering, a different tonal balance and five additional recordings.

So the answer to the question I started with is:

The difference isn’t just the spine.

The two CDs may contain the same Fleetwood Mac album, but they don’t contain exactly the same sound.

And now that we’ve got the measurements, the question becomes a much more interesting one:

Which one do you prefer?

OOONO Co-Driver NO2 – I purchased it ! – It’s Rubbish! – Refunded

Friday, August 14th, 2026

This should be called OOONO I purchased it !!!!

So lets just start by stating Amazon UK

WOULD NOT PUBLISH MY REVIEW OF THIS PRODUCT which I returned for a REFUND! – but I can review it here! 

Because it’s crap and a “scam” in my opinion! They state

“We could not post your review because it does not meet our community guidelines” – odd when so many other fake reviews, telling you how good it is!

it’s called the 

OOONO Co-Driver NO2 (2024 model)

Social Media Hyped – Rubbish – Don’t Waste Your Money

So here’s the thing…

Amazon UK refused to publish this review — the exact one below — after I returned the product for a refund.

Apparently it “does not meet community guidelines.”
You can make your own mind up…


My rejected Amazon review:

So I was intrigued — so many TikTok, Instagram, Facebook, and YouTube reviews — which I assume are clickbait and monetised.

It’s called Ooo No — because that’s what you say when you’ve wasted your money.

All these reviews on Amazon must be bots — because I genuinely don’t understand how this gets rated so highly.

Value for money? Waste of money.

Why is this even needed? You still have to pair it with your phone via Bluetooth and run the app! So why not just use Waze, Google Maps, Apple Maps, or even an old-school TomTom with the PocketGPS database — far cheaper and far more accurate.

In use, it warns far too early about cameras, isn’t accurate, and even warns about cameras on the wrong side of the road.

Yes, it’s community-driven — but there’s clearly very little verification of camera positions.

I’ve used it over ~700 miles across villages, towns and cities:

  • False warnings
  • Cameras flagged where none exist
  • Misses common mobile camera locations (compared to PocketGPS)
  • Incorrect speed limits

I would give this zero stars if I could.

Final comment: £50 paid — complete waste of money.

Just use your phone. If it’s in a hands-free dock, run Waze — don’t waste your cash.

I’m returning this for a refund.

It’s a social media–driven scam in my opinion.


Product: OOONO Co-Driver NO2 (2024 model)

So there you go — that’s the review Amazon didn’t want you to read.

Take those 5? reviews with a pinch of salt…

Return to HDCD it only took me 10 years! (Part 2!)

Monday, July 20th, 2020

I’ve recently been reminded after installing my new “balls” or Cambridge Audio “Puds” on my DAC – see here – S700 Isomagic DAC “puds” – rubber balls!,  that these outboard DACs (digital to audio converters) have the HDCD chip manufactured by  , which Microsoft purchased all those years ago. This chip decodes the HDCD information. My Arcam Alpha 5 DAC does not have this technology but roll forward 10 years, and some vintage DACs do have this ability to decode HDCD. But it is unlikely that we will ever see this technology incorporated in modern-day DACs, because rumours are that Microsoft requires a payment of $400,000 for the license!!!

and after Googling about HDCD, I found this – 10 Years ago, I blogged and wrote about HDCD, as a reminder it’s here –Hidden information on some Music Compact Discs – HDCD

I had forgotten!

It has also been removed from Windows media player in Windows 10, so it looks like the only way to play HDCD content, is on a vintage DAC!

Why Microsoft purchased the technology, not to use it, and to price it out of the market, when digital audio content is now on the rise Hi-Res Walkmans, e.g. Sony NW-A50 Hi-Res Walkman® Portable Audio Player, USB DACS, FLAC and lossless audio are on the rise again.

When we ripped to MP3, we were trying to make the rip as small as possible, to conserver storage space on our hard drives, my first MP3 player had only 128MB storage cards, today storage is cheap, and we are now ripping to lossless formats, e.g. FLAC, DSD, DSF.

In this modern-day when recording studios record to digital media and not analogue tapes, not sure why HDCD encoding is not used more, other than the lack of equipment to play it!

You need to have a CD Player that can decode HDCD or an HDCD encoded digital file. The CD I’m playing is “Brothers In Arms [2005 – 20th Anniversary Edition]”

HOW TO Rack a Raspberry Pi – RPi1B+, RPi2, RPi3

Thursday, June 25th, 2020

I’ve had a few Raspberry Pi located around the office plugged into network switches, and I wanted to tidy them up, so this is how you network rack a Raspberry Pi i 1B+, RPi 2 or RPi3.

The rack kit is available from Lincoln Binns – RP 19″ Rack Solutions

 

Have I been deaf all the years ? Two DACs ! I’ve been re-awakened…. and MP3 suck!

Tuesday, June 23rd, 2020

Finally, after almost 14 years – I’ve completed my new office layout! (Sorry Lindsey for taking so long.. I told you I would get round to it!).

Which has given me the opportunity again, to re-connect my “HiFi” which has sat in the corner of my office, gathering dust – literally? 

After re-wiring all the interconnects, making sure the cables are connected the correct way because they are “non-reversible, the signal must flow the correct way”, and re-wiring the bi-wire on the speakers.

I played the Compact Disc “Wish You Were Here” by Pink Floyd <—– the amount of detail and the stereo separation was amazing… it’s like I’ve had my head in a bucket all these years listening to streaming music and MP3s!!!!

This is not just a normal “HiFi” – Cyrus Amplifier, Cyrus PSX-R – connected to Cyrus 782 speakers – Sony CD Transport – feed into three DACs, clock synced.

Cambridge Audio S700 DACs

Cambridge Audio S700 DACs

Cyrus 782

Cyrus 782

The DACs are Cambridge Audio S700 – Isomagic – designed by John A. Westlake of Pink Triangle (1991) fame, he later went on to work for Cambridge Audio (founded 1968), when Cambridge Audio was a proper HiFi company, not to be confused with the re-branded Richer Sounds brand, since 1994, when it was purchased by Richer Sounds.

I believe John has now semi-retired, but he left us some great legacy HiFi products, and one day I’ll own a Pink Triangle DaCapo DAC!
