Standard interconnects for line level signals are not made of low capacitance cable. When you have a low amplitude signal such as a phono cartridge, you need low capacitance so the cable doesn’t roll off the high end. All the more important with a high impedance moving magnet cartridge.
Turntable Interconnects?
I want to upgrade my interconnects and ground wire from my Project RPM3 (Hanna SL MC cartridge) to the Project Tube DS preamp (goldenlion tubes) and to my receiver/preamp. Currently using Blue Jean interconnects. Not sure if turntable interconnects are a different category than digital sources, so need help on what to choose. no more than $500 each would be a nice limit. Thanks.

Thanks for the great responses... The initial cartridge was a Sumiko Blue Point No.2 MM cartridge. So im not sure if that cable that came with the Project RPM3 was only designed for MM specs. The Blue Jeans do sound good but want to upgrade and put these to use somewhere else. With the goal of upgrading the whole turntable/cartridge in the future. Not sure how to calculate impedance/capacitance/Inductance with cables yet. Any recommendations would help. Blue Jeans LC-1 Audio Cable 3 ft. Specs: Center Conductor - Solid Bare Copper, 25 AWG Dielectric - Nitrogen-Injected Low-Density Polyethylene Shield - Braid/Braid, 98% coverage, bare copper Outer diameter - .305 inch UL Listing: Yes NEC Rating: CM (Communications rated; suitable for residential and commercial in-wall installation) Electrical Characteristics:Capacitance, conductor to shield: 12.2 pF/ft Resistance, center conductor: 34 ohms/1000 feet Resistance, shield: 1.7 ohms/1000 feet Hana SL Specifications: Stylus Profile: Natural Diamond Shibata Cantilever: Aluminum Output Level @ 1kHz: 0.5mV Output Balance @ 1kHz: Less Than 1.5dB Vertical Tracking Force: 2 grams Trackability: 70 um/2 grams Separation @ 1kHz: 28 dB Frequency Response: 15-32,000 Hz Impedance @ 1 kHz: 30 Ohms Compliance: 10 µm/mN Suggested Load: 400 Omms Cartridge Weight: 5 Grams Body Color: Black Does turntable cable matter in this case from the preamp to the reciever/preamp the same way it does from the turntable to the preamp? |
How are the Morrow turntable interconnects? They are having a good sale? http://morrowaudio.com/audiophile-and-home-theater/phono-cables This is what the specs say.. is the top elite model at $995 worth it? Which one would is suggested?
