Loky 0 Report post Posted November 11, 2003 Headphones let us hear differences between tweaks more clearly... so I'd like to start this thread to compile a list of tweaks to cds. Here is what I have heard about so far: 1. Colouring the rims and inner rim with Green or Black pens EFFECTIVENESS: Good 2. Cutting the rim with a lathe so that the rim is angled 45 degrees EFFECTIVENESS: New product, unproven 3. Applying antistatic solution to reduce static, or other means to remove static EFFECTIVENESS: Not sure 4. Applying any liquid to improve clarity, reduce scratches or increase refractivity EFFECTIVENESS: Varies 5. Shining flourescent light over the cd before playing EFFECTIVENESS: rare new technique, not proven 6. Cryogenically freezing the cd in sub-zero temperatures before thawing EFFECTIVENESS: Dunno 7. Putting the cd in a sealed bag and freezing inside the freezer for 16 hours EFFECTIVENESS: Tried it, no noticeable improvement 8. Putting a special mat over a CD when loading, to balance it + block light loss EFFECTIVENESS: More harmful to the cd player mechanism than what the improvement is worth 9. Applying a special green plastic ring around the cd when playing EFFECTIVENESS: Similar to 1) but much more costly 10. Duping entire CD to black cds using EAC/cd writer EFFECTIVENESS: Tried it -- sonic improvement varies with system character 11. Digging ears thoroughly before listening to any CD EFFECTIVENESS: Definite, but has the side effect of making unwanted sounds (nagging from parents, gf, etc) more prominent also 12. Using Yamaha's AudioMaster II technology to burn a cdr at 4x speed to reduce jitter EFFECTIVENESS: Mild if noticeable at all. Better effect on black Melody cdrs though 13. Sanding the rim of the cd EFFECTIVENESS: Negligible if the rims were unsmooth in the first place. 14. Applying damping material onto the cd's label surface to control resonance EFFECTIVENESS: Dunno 15. Make 6 black or green lines emanating from the centre of the CD. Each line is a little less than one quarter inch wide. It's like cutting a cake into 6 equal pieces. EFFECTIVENESS: Never tried. 16. Throwing the cd away and listening to the vinyl equivalent. EFFECTIVENESS: This is not a tweak, but I'm sure vinyl enthusiasts wish every newly released cd has a vinyl equivalent! Anyone who can contribute more tweaks/info/opinions to this thread is most welcome! Share this post Link to post Share on other sites

Loky 0 Report post Posted November 11, 2003 (edited) The fluorescent lighting thing + the lathe to shave the rim to 45 degrees, are featured in Positive Feedback, a very high-end audiophile publication. Dunno whether they are hallucinating or not, but here's the story: http://www.positive-feedback.com/Issue1/swartz.htm Edited November 11, 2003 by Loky Share this post Link to post Share on other sites

N@Z 0 Report post Posted November 11, 2003 No wonder all my CDs sound good as I always look at them under the fluorescent lights before putting it in the CD drawer! LOL... I'm game as long as it doesn't cost me anything! Although I probably couldn't tell a difference. Share this post Link to post Share on other sites

Q00 0 Report post Posted November 11, 2003 (edited) Cryogenics is the process of bringing down the temperature of an item to absolute zero (around -275 deg c iirc) and treating the item until the molecular composition of the item itself has changed and slowly bringing it back up to room temp. I have read on head-fi that some guys do treat their tubes cryogenicaly and with outstanding results. Process is very time consuming so as to prevent the tube from shattering. Roughly 24hrs to bring it down to absolute zero, another 24hrs or more to treat it and finally another 24hours to bring it back up to room temp. The tubes were originally flat sounding or had poor sounding qualities but after the treatment, they were very comparable to nos tubes. Sounds very promising and there are claims that it is permanent and that you can treat any tube and they will all sound very familiar after the treatment. I do not think it will make any difference since cd's are all read digitally Edit: some things i left out..zzz Edited November 11, 2003 by Q00 Share this post Link to post Share on other sites
Q00 0 Report post Posted November 11, 2003 11. Digging ears thoroughly before listening to any CD EFFECTIVENESS: Definite, but has the side effect of making unwanted sounds (nagging from parents, gf, etc) more prominent also I think that digging your ears are very harmful in the long run unless you have a physical item in there (which i think is very weird). Instead, try using ear wax remover ear drops like most of us do here. Much more effective but requires at least 4-7days of continous use to fully remove those stubborn wax in those hard to reach areas. You will definitely hear a big difference and will be able to appreciate the music more. Share this post Link to post Share on other sites

Q00 0 Report post Posted November 11, 2003 surprisingly crygenically treating the tubes is cheap even though it sounds super expensive for such a time consuming process. price quoted online was 5usd a tube i have yet to try the black cd's yet cuz i just bought some just now but the slower burning speed sorta makes sense in that you do reduce jitter in the recording.

Where can I get some of this ear drop? Just go to the chemist and buy it over the counter? Have you ever tried the ear candles? Share this post Link to post Share on other sites
