This is a problem I wasn't even aware existed until recently! Impedance matching.
Mcintosh website has a downloadable file which quotes the MC2301 tube mono amplifier's "input impedance" as being 47,000 ohms.
I would preferably like to mate this amp with a Shindo pre amp, either the Masseto model, or the Vosne Romanee model. There are several figures available with the word impedance in them, so I didn't know which one to quote for each of the pre amps, so if you could check here
I would greatly appreciate it.
I read that preferably there would be a 15:1 to 20:1 ratio (I think) and all the figures for the Shindo pre amps seemed to be way off that when compared with the MC2301's 47,000 ohms figure, but it's very likely I'm overlooking something here.
So, in terms of impedance matching, can I successfully mate the Mcintosh MC2301 with either the Shindo Vosne Romanee or Shndo Masseto?
