2.5mm Spacer / Shock Absorber / Weight for DENON DL 103 Series Cartridge made of Teak Wood

A cocobolo wood body for the Audio-Technica AT91 cartridge brings a dramatic and welcome transformation , elevating this humble, entry-level cartridge into something that sounds far more refined, rich, and musically engaging . Cocobolo, a very dense and oily tropical hardwood from the rosewood family, is known for enhancing harmonic complexity , taming unwanted resonances , and boosting tonal depth — all things the AT91 can benefit from.

🔊 Sound Characteristics of Cocobolo Body for AT91:

---

🎧 Subjective Listening Impressions:

• The plastic “budget cartridge” sound is gone — cocobolo gives the AT91 a weightier and more analog presentation .

• Highs are no longer brittle or splashy , but silky and extended .

• Midrange becomes surprisingly lush , especially in vocals, acoustic guitar, and strings.

• Bass gains real definition and depth , which the stock body simply cannot deliver.

• Overall, it's more musical, involving , and surprisingly audiophile-like for such a simple generator.

🔨 Why It Works So Well:

The AT91's generator is basic but surprisingly competent , especially with elliptical upgrades (like ATN95E or 95EX styli). The weak point is its thin plastic body , which allows unwanted vibrations and resonances to blur the signal. Cocobolo's extreme density and internal damping qualities help:

• Absorb parasitic vibrations that smear transients

• Reduce resonant peaks in the upper mids and lower treble

• Enhance bass coupling with the headshell for better impact and articulation

🔧 Tip : Use a heavier headshell or tonearm if needed — cocobolo adds mass (often 5–8g more than stock), which can slightly lower resonance frequency, especially with heavier wood bodies.
