Frank, thanks for putting me straight. I think I knew that, but got carried away in an enthusiasm of over-configuration...

I don't have a Dynavector XV-1s so can't claim to know what will definitely work best, but here's how I'd start out:
The user manual describes it as a low-output moving coil cartridge, so set the Cartridge Type to MC. The output voltage is 0.3 mV at 1 kHz, 5 cm/sec so I'd try setting the maximum output level to 500 μVRMS. The recommended load is "more than 30 ohms" so 100 should be reasonable. There's no suggested capacitance loading so I'd probably pick something in the middle of the range - perhaps 300 pF.
Think of those as starting points for experimentation: you'll probably be able to "tune" the sound of the cartridge a bit by adjusting the R/C loading (as noted in this post on Audiogon, for example). If you have the cartridge set up "just so" with an existing phono preamp, perhaps you can use the loading values closest to what that uses. Also, it's better to err on the generous side for the maximum output level -- that is, use higher rather than lower values -- to avoid the possibility of clipping.
In the Advanced settings, I'd suggest enabling the Auto Wi-Fi Standby option: that disables the wi-fi interface in the Devialet when the phono input is selected. If the wi-fi interface is enabled you might otherwise hear a very quiet periodic "tick" in one channel. The RIAA curve and sampling rate are a matter of taste, but the consensus seems to be that the defaults (1976 RIAA curve and 96 kHz sampling) are preferred.
Hope that helps, apologies in advance if I'm in grandmother/eggs territory, and please update the thread to let everyone know what you find works best.

Thanks very much, Ian. I like what I am hearing so far with these settings. I'll experiment some over the next few weeks and see how it goes. I appreciate your suggestions!

Thanks Chris, glad to hear it's working. You did see f1eng's correction to my post, pointing out that you don't normally need/use capacitive loading with an MC cartridge?

Yes, thanks to both you and f1eng. Very helpful tips, which I certainly appreciate.
Hi,
anyone knows which settings I should configure for my Linn troïka??
Linn specifies: recommanded load 470 Ohms, output @ 5cm/s 1kHz: 300 uV
I was thinking of - a max level of 500 uV, a loading resistance of 460 Ohms and a loading capacitance of 0 pF...am I right?
many thanks
JC

You can probably use a bit more gain (max level 300-350uV) for the Troika going on the spec. the other setting are spot on I would say (of course you can adjust all these parameters real time with RAM).

Does anyone use a Koetsu cartridge? The new RAM doesn't have Koetsu as one of the manufacturers. I'm using the Black Goldline. Here are the specs:
Koetsu Black Goldline Technical Data
[*]Body: anondized aluminum
[*]Type: moving coil
[*]Coil wiring: copper
[*]Magnet: Samarium cobalt
[*]Cantilever: boron
[*]Output: .4mV
[*]Frequency range: 20Hz-100kHz
[*]Channel separation: 25dB/1kHz
[*]Inner impedance: 5 ohms
[*]Channel balance: .5dB/1kHz
[*]Recommended impedance: 30 ohms
[*]Weight: 10.8g
[*]Compliance: 5x10-6cm/dyne at 100Hz
[*]Tracking Force: 1.8-2.0g
Thanks for any help.

I'd start with 400-450uV. 0pF capacitance. loading 100Ohms (30Ohms is the recommended minimum).
Hope this helps.

Picket up a Rega RP8 today with Apheta 2 cartridge. Oddly the devialet wants to set it at 200ohm and 500 microvolts, even though the cartridge specs say 100ohm and 350 microvolts.
Anyway I set it to what the devialet wanted and then I figured I'd tweak on the fly. I go to tweak and the devialet tells me it's set at 2500 microvolts. The setting from my previous Sumiko cartridge, another bug.
Right now my magic setting for the Apheta 2 is 85 ohms, .35mV and 1.82g of tracking.
