Description: Denon DL-305 low output moving coil cartridge retipped with UPGRADE 0.08 mm square shank, ultra low mass, high polish, grain oriented, gem grade, Orbray Micro Ridge r/R 2.5/80µm line contact diamond, surface-mounted to original 0.28 mm diameter amorphous chemical vapor deposit (CVD) hollow pipe bottom cantilever. This cartridge is 100% like new. Tested at 1.25g VTF. Hear your music like never before or remember it how it was if you owned one of these amazing cartridges in the past. These are no longer made. The Orbray Micro Ridge is known to be one of the most distortion-free diamonds available, and it is super quiet in the groove as well. The hollow boron pipe cantilever represents the pinnacle of low mass/lightweight cantilever technology, no longer produced and now mated with a top of the line high tech diamond for a rare top quality cantilever-diamond combination that cannot be found in a brand new cartridge today. This particular cartridge checks out with an above-spec fantastic better-than 35dB channel separation and 0dB channel balance difference. These are brand new NOS -type numbers. Obviously, the suspension on this is also in excellent condition. Cartridge is in excellent condition as described above and sounds absolutely fantastic at spec 1.0g VTF tracking force and has been thoroughly and extensively tested and analyzed and is guaranteed to work to your high expectations or your money back.

Manufacturer’s Notes: MC type cartridge using amorphous boron pipe. A new material, amorphous boron pipe with a thickness of 0.025 mm is used for the cantilever. Boron it is light, boron has an excellent specific rigidity (Young's modulus / density) and a melting point of 2,300 ℃, making it the most suitable element for cantilever materials. Amorphous boron is an amorphous state filled with small particles, and its fracture strength is approximately three to four times greater than that of crystal boron, which is an assembly of large crystals. In order to use this material in the optimum condition, we have succeeded in forming ultra-thin pipes using our proprietary C. V. D. (Chemical Vapor Deposition) method, and have realized uniform and dense boron film surface. This reduces the effective mass of the vibration system to 0.168 mg, minimizes the mechanical impedance in the high-frequency range, and enables faithful and accurate tracing with light needle pressure. Solid diamond special elliptical needle has been adopted for the needle, achieving 0.01 mg or less. The tip of the boron pipe that fixes the needle is tapered and installed in a precise rectangular hole made by laser beam processing. The generator coil uses a rigid resin cross-shaped winding frame to lighten the entire vibration system and to achieve an optimum mass balance, eliminating the characteristic slack caused by split vibration. This winding frame method allows the coil to be wound symmetrically around the vibration system axis, and has the advantage of matching the characteristics of the left and right channels. For the internal structure, rare-earth cobalt magnet and rational yoke structure are adopted in order to obtain a small size and strong magnetic field. In addition, the vibration system is supported by the one point support system proven in the DL-303 and DL-103 series, so that the coil can always be held in the center of the magnetic field, and the generation of strain in the power generation system is kept low. I stand behind all my retipped cartridges, styli and retipping services. Check my feedback if you’ve got any lingering doubts. The fact is, I can make your cartridge sound as good or better than new because I run a very tight QC regimen. I personally adjust and tune each cartridge until it operates at its best, which isn’t always the case when you buy new. Thanks for looking and, by all means, if you have any old broken or used worn cartridges or styli lying around, please contact me. I am always looking for donors. Competitive prices paid.
