Pre3 impedance question - World-Designs-Forum

Sorry for the newbie question. Perhaps a dumb question too.

I read my Pre3 has low output impedance of around 12 ohms. I read that, especially with tube preamps, that it worth checking the input impedance of the power amp the Pre3 is connected to. I am thinking of buying Nord One SE MP NC252 'Hypex NCore' power amp that has an input impedance of 47K Ohms - so my dumb question is will the Pre3 be 'okay' with this ? as in i will not suffer any sound degradation or possible damage e.g. to the preamp tubes ?

Thanks very much for any help.

Pete.

No problem at all. Bob

Thanks Bob. I actually got a reply from Matthew, which was great. Thanks again. All is good regarding my impedance question with the PS3 and the power amp i mentioned. In fact Matthew said it happens to be the same as the World Designs power amp.

cheers everyone
