Technics SL-1210 Mk7 & SL-1210 Mk2 measurement comparison
Searching for information on the differences between the SL-1210 MK7 and SL-1210 MK2, I found this forum post and linked article (in greek).
Here's a summary of the post with the key differences and similarities between the two models.
Rotation Quality
- Mk7: Excellent rotation quality (0.036% IEC, 0.036% NAB).
- Mk2: Close but varied (0.297% IEC, 0.032% NAB) due to arm suspension tolerances.
Rotation Accuracy
- Mk7: High accuracy with modern direct driving but less precision than a micrometer setting.
- Mk2: Similar high level with a slight difference (0.137%).
Wow & Flutter
- Both Models: Similar W&F variations over time, staying within [-2, +2] seconds.
- Average W&F: Mk7 at 0.072%, Mk2 at 0.079%.
- Peak-to-Peak W&F: Both at 5%.
Frequency Analysis
- Low Frequencies: Both show very low coordination levels at -60dB.
- Higher Frequencies: Mk7 around/below -100dB, Mk2 slightly different but similarly low.
Rumble
- Mk7: Very low rumble with minor tuning spikes.
- Mk2: Similar low rumble with minor frequency differences.
Signal Reproduction
- Harmonics: Both models show the second harmonic at -40dB, with Mk2 having lower noise levels up to 2kHz.
- Higher Harmonics: Mk2 changes slightly above +6dB.
Frequency Response
- Low Frequencies: Focuses on 20-30Hz range.
- Higher Frequencies: Minimal differences above 100Hz.
- Acoustic Feedback: Mk7 has improved isolation, particularly in the 50-80Hz range, due to changes in materials and support points.
Percussion Response
- Both Models: Good compatibility with Denon's head, with Mk2 showing slight instability due to tolerances.
Conclusion
- Both models are similar with small measurable differences.
- The Mk7 maintains high quality and performance, despite cost reductions, while nearly matching the older Mk2 model's performance.
South-Korea Kimchi Masters
I didn't know it was possible to make Kimchi with seafood. I am pretty curious to taste it.
Sorry To Bother You
I can't remember how I heard about Sorry to Bother You but I'm so glad this movie crossed my path.
This surreal production touches on a myriad of subjects with an intelligent lens: Black identity, big-corp America, private labor camps, transhumanism, political activism, class defection, social networks absurdities, and more that I can remember of.
The mix of science-fiction and absurd is brilliant. Just like Idiocracy can be pretty brilliant as well.
Los Caminantes
The guy known as Bald and Bankrupt (a travel vlogger known for exploration of ex-soviet countries) delivered an absolute gem of gonzo journalism.
In 2023, with another travel vlogger called Timmy Karter, they challenged themselves to follow the migrant trail from Venezuela to Mexico. The Venezuelan population is hit by a severe crisis , forcing individuals to flee the country for hopes of a better life.
In a three-part video series, Bald and Bankrupt gives us a window on the extreme dangers these people face. We also witness their immense desire to build a better life, and the bravery they are made of.
