Q impedance?

[charger]

what is Q impedance ? I can't find in the Q specs page

thank you

Which impedance?

Input is about 100K, output impedance is 2K stock, and 4K with the PJCCS.

OK THANK YOU !

Does this means that Q is a low impedance preamp ?

Outputs of sources and preamplifiers need to be low.  Some solid state products have an impedance like an Ohm or less. 

Tubed devices are higher, like the Quickie.  They are at their best driving a higher load, say 10 times higher.  This is why Bottlehead amps have a 100k Ohm or higher input impedance.

How would you define a low impedance preamp?

I am using the Q to drive a class D amp with 12K Ohm impedance , do you think it's a good match?

12,000 / 10 = 1,200
1,200 < 2000 < 4000

Numbers matter less than sound. These are rules of thumb, not laws carved in stone. If you are satisfied with the sound, then that is far more significant than any formula.

Totally agree!

In fact, specific to the Quickie, if you put in the PJCCS the source impedance will double, as mentioned above - but the tube will see a much higher total load resistance and will perform better with lower distortion.
