Load Settings Help: Luxman E-250 and Koetsu Black Line
Hi Folks, I could do with some help as I don't understand load impedance or capacitance settings.
I have a Luxman E-250 for my phono stage which is connected to a Michell Gyro SE with a Tecnoarm 2 and a Koetsu Black gold line cartridge mounted on the arm. This all feeds a C900u and a M10x.
The settings on the E-250 are default but I feel there is more to be had with the sound based on some other similar setups i've heard. Could I get some recommendations on load settings?

@viridian Thank you. I completely missed that on this preamp. I'll have a play with the options at the front to test what sounds best |
Information on the maker’s site is pitiful "Black, Goldline, least expensive For many, their Koetsu journey starts with the Black Goldline. While it is the most affordable Koetsu, it doesn’t sacrifice what makes a Koetsu special. The Black Goldline uses many of the same parts as the higher end models and the result is effortless musicality and magic. "From the clarinets in the opening to the deeply textured final chord of the first movement, the Koetsu’s performance was impossible to ignore: This wasn’t just pretty sound in place of the music but sound as a part of the music." Art Dudley, Stereophile “The thing that really grabs me when listening to this moving coil cartridge is its overarching realism, musicality, clarity, and wide open extended sound.” Michael Corsentino, Positive Feedback
Specifications Anodized Aluminum Body Copper Coil Wiring Samarium Cobalt Magnet Boron Cantilever 0.4 mV Output 10.2 g Net Weight Recommended Tracking Force 1.8-2.0g Recommended Load 75-500 ohms $2,995" they don't even tell you it’s a moving coil, (the reviewer mention’s that it is) or it’s coil’s impedance (member viridian tells us above it is approximately 5 ohms coil impedance), or publish any performance specs for stereo separation or channel balance. they give a wide range of recommended load 75-500 ohms, and tell you it has a boron cantilever, but tell me, what stylus shape is it? guidance formula for loading a moving coil is start with 10x it’s coil impedance, which is approximately 50 ohms, yet they say 75 to 500 ohms. ........................................ top of the line, Blue Lace, $16k, this is all they tell you "Specifications Blue Onyx Stone Body Silverplated Copper Coil Wiring Platinum Magnet Boron Cantilever 0.3 mV Output 12.5 g Net Weight Recommended Tracking Force 1.8-2.0g Recommended Load 75-500 ohms $15,995" ...........................................

still hopping about, found a review of a Koetsu Rosewood from 2007 with some info, but tell me what is the Stylus Shape? "Stylus: specially designed and ground for Koetsu" "Description: Low-output, moving-coil phono cartridge. Stylus: specially designed and ground for Koetsu. Output: 200µV (1kHz, 5cm/s). Internal impedance: 5 ohms. Frequency range: 20Hz–100kHz. Channel separation: >30dB/1kHz. Channel balance: within 0.5dB/1kHz. Recommended VTF: 1.8–2.0gm. Recommended loading: 5–100k ohms. Compliance: medium-low. Recommended tonearm: medium-high mass." a typo? Recommended loading: 5–100k ohms |
