Resistive Loading RP-1 and Ania Pro


I just went back and reviewed the setting for my aforementioned pre & cart. Rega's web site says Ania Pro load impedance is 100 ohm.  I looked at my dip switches on my RP1 and they were configured at 300 ohm.  Besides having to turn the volume up what I perceived as abnormally high I thought it sounded fine.    Getting ready to have a listen tonight but what should I expect to change?

“Too low” would tend to sound dull, and you’d sense there was less gain. You’d want to turn up the volume a bit. That effect becomes increasingly noticeable as you reduce the input impedance in relation to the internal impedance of the cartridge.

so if you had the load set to low what would the affect be?  Brightness, sparkle ....?

ahh.  I just fired it up and I thought yeah maybe it do sound a bit better.  But I have not listened to my TT in many months, been all streaming.  So I checked myself and thought that it had been so long that the only way to tell was to go back.    But now I dont have to do that.

 

Thank you. 

PS i was considering dumping my TT but after firing it back up i think I will keep it. 

Assuming "Ania Pro" is your cartridge, and that the recommendation is to load it at 100 ohms, and assuming "RP1" is a phono stage formerly set at 300 ohms input impedance and now set to 100 ohms input impedance, most likely it will make no significant difference.  But because you made a change, you will be inclined to hear a difference. If a cartridge is suitably loaded at 100 ohms, it will work nearly exactly the same at 300 ohms.  Manufacturers almost always state the recommended load impedance for a cartridge as a given number of ohms, or greater.
