Well, this has been an interesting thread.
I do appreciate everyones response in regards to loading.
I did a little internet search and here is what I came up with in regards to loading.
I am quoting from Analog Planet, a site of which I've never heard of prior to today.
"The Delos, machined from solid aluminum billet, features a 2.5µm x 75µm Namiki microridge line contact stylus, a solid boron cantilever and coils of 6-N high purity copper. Output of the 7.3 gram cartridge is a relatively high 0.6mV@5cm/sec while internal impedance is moderately low at 8.2 ohms. Like other Lyras the Delos uses a yokeless, Neodymium disc direct magnet system. The connection pins are silver plated.
As with any line contact type stylus, correct VTA/SRA is critical to optimizing performance so a VTA adjustable tonearm is recommended if not mandatory. Compliance is approximately 12x10cm/dyne at 100Hz. Recommended tracking force has a narrow window of 1.7g—1.8, with 1.75 “preferred.” Recommended loading is between 91ohms and 47kOhms determined by listening. VTA is 20 degrees, which Lyra says is achieved with the arm parallel to the record surface. As with other Lyras, the generator is integral to the body as opposed to being a completed mechanism inserted into a body. The result is better mechanical grounding, energy transfer and inherently correct alignment of the generator and body.
You can determine the “mathematically correct” loading according to Carr’s instructions by determining the total capacitance between the Delos and the phono stage. While the ultra low inductance of moving coil cartridges makes capacitive loading far less critical than it is with MM cartridges, there remains a relationship between capacitance, load value, bandwidth and the amplitude of the ultrasonic resonance.
Usually though, a setting of 10X the internal impedance is a good starting point, which is why Lyra species 91 ohms as the low, which is just above 10X the Delos’ 8.2 ohm impedance. According to the instructions if your cable’s capacitance is 100pF per meter, for instance, loading at 390 ohms will suppress the peak to 3dB while 200 ohms will suppress it to 0 at the expense of slightly poorer phase response and reduced dynamics. I went with 500 ohms but listened at 100 ohms as well, which is where I preferred it.
One interesting new design wrinkle here is a new body angle and a “pre-angled” damper system that aligns the coils and magnetic circuit with the application of the proper VTF. Most cartridges, Lyra claims, provide this alignment only when no tracking force is applied."
I dug out my manual for my C-J EF1 phono stage. (btw I run the phono stage into a C-J Premier 17 LS, a very high quality tube preamp I acquired from a good friend 20 years or so ago.) The avail loading is: 200 ohms, 500, 1.9K, 9.6K, and 47K. These are set by dip switches. One sentence I will quote from the manual. "The factory preset 47K load (all switches off) will be best suited to most cartridges."
C-J does not mention MM or MC carts in any of their instructions....go figure.
I am running Audio Quest King Cobra interconnects throughout the entire system chain of equipment. I have no idea how to calculate the mathematical correct loading; and even if I could, it may not be avail in my phono stage. Since my Pre amp and Amp are tube C-J equipment, I'm hoping C-J did all the 'correct engineering' so their equipment runs together in harmony. The way my system is stacked it's a hassle and 1.5 hr job to switch the loading, which requires me to get on a ladder...no fun. For the time being I'll leave it at 47K. If I decide I don't like it, I'll switch to 200 ohms and call it a day. I really don't want to 'play around' with loading. Just find the best setting and leave it alone...Thanks for all the feedback!
