Can you please explain how the 2 loading options for the phono stage work for MC? I have a Soundsmith Hyperion 2 with output that is MC level but loads best somewhere between 1-2k.
- The standard MM/MC module states for MC "16 load settings from 26 to 400 Ohms".
What are the 16 steps?
- With the optional Remote Cartridge Loading (RCL) module it states
"255 individual settings for high precision cartridge loading" and
"Load Range from 5 to 5000 Ohms"
- Does this sort of "override" the standard 26-400 or is there a dependency?
I remember talking to you about it at RMAF but can't recall exactly how it works.
- Are the 255 settings at a fixed interval or a pattern?
- Could you post a spreadsheet of the 255 settings on your site somewhere?
With MC, the max load will actually end up being 2K.
John (Bent Audio) and I have made some changes before finalizing the PCB, and that was one of them!
So no matter if you are using only the LIO Phonostage (via the DIP switches to set the MC load), or the LIO Phonostage with
the RCL (remote cartridge loading) board to set the load, the highest load setting will be 2k for the MC.
- With just the LIO Phonostage, there will be 16 different load settings via the DIP switches.
- With the LIO Phonostage + RCL module, there will be 255 load settings, and this can be done on the fly as you listen... via
the front panel or remote.
[When the RCL module is used, you won't be using the DIP switches to set the load].
Yes - I will be posting the load values for both soon. If you are using RCL, then the front panel will also display the load setting
in ohms when you are in the "LOAD' mode, so you will know what you are set to.
And speaking of the LIO Phonostage, we are now using step-up transformers for the MC input
. The step-ups add 20dB on top of the ~ 40dB of the MM JFET stage. A cylindrical mu metal cover goes around the step-ups. They are mounted onto the LIO Phonostage board. Initially I was going to use a JFET stage for the 20dB gain at the MC input as well, but after trying the step-ups, there was no comparison! The step-ups not only had much lower noise, but the sound has more punch, more air, more delicacy... it is "tasty!"
More details and pics of the phonostage are coming soon enough...
