Audiolab 6000CDT, bright sounding, burn in time?

[Norcal]

Of course, we're not fun! We're a bunch of super hardcore science geeks staring at an AP with our lab coats on all day.

Don’t forget ‘listening to test signals instead of music’…

By simply sticking "Silent Coat" 4mm aluminum backed Butyl constrained layer damping sheet strategically inside the case and on susceptible parts of the mechanism he has achieved the following:

Point of order.

Strategically implies some kinda of strategy, a plan maybe even some testing to isolate the exact source of the issue... from the looks of it I would suggest it was "stick this stuff on every available surface".

One would imagine in a reasonable design the CD mechanism (where it meet the chassis) would be damped in some way?

I am surprised that the sides of the transformer escaped treatment... imagine the gains missed by not doing this.

First of all, that is not a proper burn in technique for transports. You can't just leave the player playing random music because there could be serious consequences.
Let's just hope your player isn't ruined.
You need to prepare music material in advance and you have to do it in order. Before you even start playing some music, you need to play 10 minutes of pink noise so that you try to negate the damage of random music playing.

You said that the sound is clinical? Then you need to start with mid bass, so play some 50s Jazz and use only Impulse and Bluenote releases. Think Miles, Coltrane... 60hours
After that you need only 30 to 40 hours of 2000s minimal techno for sub bass.
Now the hard part is to open up those kicks and to solidify the bass and for that you need some 80 hours of drum n bass.
All this is good for the bass, but it will close up some mids, and to reopen them, you must play 40 hours of male crooners from 40s to 60s like Sinatra, Dean Martin, Early Bennet... But please, no Michael Buble or you will mess up the imaging.
Now finally for silky smooth upper mids and highs you can play modern jazz female vocals like Nicki Parrott, Emilie-Claire Barlow and similar. 40 hours will do it.

The important note is that you can't just let the player play without you listening or you will develop something which is called the Cold Burn and that will mean that your player would be unburninable anymore.
Also, you should own original CDs of the material, but play only the burned copies because it will burn in the player without wearing out the motor. And please, use only 8x burn speed for CDs, not the 16X or you will cause overburn.

Good luck!

Brilliant.

Is there something wrong with that?

Spoiler: The Objectivist’s "Strictly Scientific" Playlist

"For when your ears are an unreliable measurement tool."

1. "1kHz: The Benchmark Banger"
   • A tone so pure, even your DAC will shed a tear of joy. Guaranteed to measure at 0.0001% THD.
2. "White Noise: The Sound of Truth"
   • Immerse yourself in the chaos of all frequencies, perfectly balanced (as all things should be). Ideal for disproving golden-ear claims.
3. "Pink Noise for Golden Egos"
   • Because real objectivists know flat power response isn’t optional -it’s a lifestyle.
4. "Bass Sweep Drop (20Hz to 20Hz)"
   • A short but sweet demonstration of why your subwoofer doesn’t deserve a bigger amplifier.
5. "Square Wave Scorn"
   • A brutal, unapologetic diss track for anyone who dared to call tube amps "warm."
6. "440Hz: The Only A You’ll Ever Need"
   • Why listen to a symphony when one perfect pitch suffices? Bring your tuner -this one's not for casuals.
7. "Dynamic Range Deathmatch"
   • Battle-ready tones for proving that your favorite recording is actually over-compressed garbage.
8. "Stereo Imaging: The Ping Pong Prelude"
   • Left. Right. Left. Right. Test your setup -and your patience -with this hard-panned classic.
9. "Impulse Response Rhapsody"
   • A percussive masterpiece where every peak is a reminder that timing accuracy is non-negotiable.
10. "THD Tango: Zero is Sexy"
    • A sultry tone designed to expose harmonic distortion in all its ugly glory. (Because if you can hear it, it’s too much.)
11. "The -3dB Breakup Ballad"
    • An ode to poorly designed crossovers and the heartbreak they leave behind.
12. "Nyquist No-No"
    • A high-frequency thriller that stops just short of 22.05kHz -because anything beyond is a myth.
13. "The RMS Blues"
    • A slow, soulful track dedicated to all the misguided fools who only measure peak power.
14. "Multi-Tone Mashup Mayhem"
    • Perfect for those who think single-frequency tests are for amateurs. Can your amp handle this harmonic chaos? Probably not.
15. "The Silence Sonata (0dB SPL)"
    • 3 minutes of absolute silence, so pure that you can finally test your noise floor -and your existential dread.

Even though a CD transport operates largely in the domain of ones and zeroes it would appear that resonance and vibration can play havoc with the sound quality.

The gentleman who owns this example has found the answer to the horrific and destructive power of these unwanted physical assaults.

By simply sticking "Silent Coat" 4mm aluminum backed Butyl constrained layer damping sheet strategically inside the case and on susceptible parts of the mechanism he has achieved the following:

"Immediately sounding better already from power up in terms of solidity, soundstage depth, separation and detail.
The sound is bigger, clearer and projects better. Speaking of detail, the player sounds more relaxed, but more detail is coming through?
It's like it has more time to play music, things sounding more 'right' in terms of timbre and timing."

You can thank me later.

Ha ha.

I owned a rotel transport ,that did not lock properly to my DAC . I figured why . Previous owner had improved the thing by putting blu-tac on the oscillator crystal ( its housing ) it apparently disturbed the cooling enough to put it of a bit , when removed all was good again.
