Impedance Matching Preamp/Amp Assiance Pls?

I'm looking to purchase a Cary SLP-05 that has an input impedance of 100k Ohms (XLR) and a gain of 27db. My Spectron MK2 has an input impedance of 50k Ohms using the XLR inputs (which I use).

What is the consequence of using the Cary with the Spectron regarding its compatiblity relative to the impedance and gain specs? Any issues I should be aware of?

Thanks in advance for your comments.

Nick,

I think what matters is the output impedance, which is 400 ohms for the Cary SLP-05. Given the Spectron's 50K input impedance, you should be fine. The rule is 10:1.
