CODA Continum 8 Imput Impeadence

Thanks all for the very useful information. As long as I stay with an Allnic (which isn't the worst thing in the world🙂) I should be ok.

yes, their website is a mess! The #8 is available in stereo or mono (v1, v2, v3) each offering different power outputs, as you move up in power you move down in class A bias (18watts to 8watts)

they em will build the# 8 to your requested configuration in the new chasssis with meters and all the millwork on the faceplate or in the TS/TM chassis witch offers a much "less busy" look.

james at destination HiFi has been a good source of information due to his long relationship with Legacy speakers 

thanks again, great information! I appreciate you all taking the time to respond...

Odd that the Continum #8 is not on the Coda web site as I was interested in this amp as well.

The outputs of the Allnic L-1500 are transformer coupled, and are described in its manual as having an output impedance that remains essentially constant (at 150 ohms) across the entire audible frequency range. So it should be fine driving 10K.

It would be a different story in the case of the some tube-based preamps which have capacitively coupled outputs. In those cases the output impedance might rise to much higher values in the deep bass region than the specified output impedance, which is usually based on a mid-range frequency such as 1 kHz. But that is not the case here.

The rule of thumb is the input impedance should be at least 10 times the output impedance. At 10k you should not be concerned!

You are correct sir!
the true values are 75k unbalanced and 10k balanced
This information came from Destination HiFi who called and spoke to Coda, still very low

Thanks

I'd hazard a guess that it's a misprint. Contacting Coda for confirmation might be helpful.
