Myths (Vinyl)
Vinyl always sounds better than CD
naw fuck cds
The vinyl surface is heated to several hundred degrees on playback, and repeat play of the same track should wait at least several hours until the vinyl has cooled
dem cds is shit
Proper vinyl playback is click-free
cds suck dick
Vinyl is better than CD because it reproduces higher frequencies than CD and avoids anti-aliasing filter issues at the frequencies CDs can reproduce
vinyl fuck cds n da ass
Vinyl is better than digital because the analog signal on the vinyl tracks the analog signal exactly, while digital is quantized into steps
nigger assed cds need 2 get fucked
Vinyl has greater resolution than CD because its dynamic range is higher than for CD at the most audible frequencies
vinyl is better dan shit digital, muh nigguh
Adding a penny to the headshell improves tracking/sound
The trackability of a cartridge is related to the mechanical parameters of the tonearm and stylus assembly. Adding weight to the headshell (and adjusting the counterweight to compensate) increases the effective mass of the tonearm and reduces its resonant frequency. If the resonant frequency is excessively high - 15-20 Hz as measured by a test record - the weight may improve trackability by moving the resonance out of the audible range. Otherwise, it will generally only reduce trackability.
A cartridge is permanently damaged and should be replaced if the stylus appears even slightly bent
Bent styli cause azimuth and alignment errors which may be audible. In extreme cases they can cause record damage. Cartridges are hand-built and always have some finite tolerance in their construction. No stylus is perfectly straight. That said, if a brand-new cartridge arrives visibly bent, it is probably a good idea to return it.
Belt-driven turntables are better than direct-drive turntables
Belt drives are far easier to implement than direct drives, easier to improve, and arguably easier to repair. Well built direct drives have speed and rumble tolerances as good or better than well built belt drives.
Subjective claims to the improved musicality and audio quality of belt drives are disputed and not well agreed upon by all listeners.
Belt drives hold their value just as poorly in the used market as direct drives.
Direct drive motors tend to last a very long time (some original-model SL1200s may still run without any maintenance). Belt drives need new belts on a semi-regular basis and tend to have noisier motors at the same price ranges as direct drives.
There is a common myth that a direct drive will "hunt" for the correct speed and cause audible speed variations. This has no basis in reality.
It is believed that direct drives are better at handling dynamic stylus friction than belt drives, except in cases of very poor direct drives or very good belt drives.
Some examples do exist of direct drives of inferior quality.
Stock tonearms on direct drives tend to be much less expensive than the tonearms that come with belt drives at similar price points.
