What are ideal impedences between tube and ss?

There are a few threads on Agon on this subjcect but I want to know what is considered a low output and high input impedence(numbers). I have a AE-3(Cary) with a 560ohm output. My Audible Illusions amp(S-120) has a input of 35K. To me this looks like a match but without a reference I'm not sure. The two together sound great! I'm not a tech but do like to know what's going on synergy wise. Thanks in advance and enjoy the holiday.

Thanks for your reply. Tell me this, if the pre has a high amount of gain and the amps sensitivity is low enough would that help with the current transfer you mentioned. I don't listen very loud and my spkrs are 89db(Meadowlark Kestrals).Or does this have anything to do with my question. I'm trying to get a handle on this in case I want to change pre's or amps. Thanks again.

Hi South:
Does this help or is it too arcane?

I think it is the latter. Sensitivity doesn't pertain to your original question.

Your setup, like most, is designed to transfer voltage from the pre to the power, not current. Some current will flow. But if the input impedance of the power amp is high enough, and yours is, then this current will be minimal and everything will be fine.

My thanks to Herman and Clueless for the valuable info. I went to a vocational high school many moons ago and while trying to stay up on hardware these days the theory aspect of this hobby seemed to slip away from me.
