Preamp to amp compatability help.

Hello everyone and thanks for taking the time to read this.

I am seriously thinking of buying the Coincident Statement Line Stage, that has an output impedance of 500 ohms, it doesn't specify RCA or XLR so I assume its the same for both.

I would use my Classe CT-2300 amp at least initially, it has a 50k ohm input impedance  so I would expect they would be compatible.

If I go this route I expect that soon I would start to think about a different power amp. Maybe a tube amp, maybe something else. I have been looking at some possibilities and have found the input impedance varies greatly, some as low as 15k ohms.

So my question is how low input impedance can I use and still expect no compromise on performance?

Thanks for all responses, I look to your expertise for help.

Thank you Al, I always enjoy reading your educational and informative posts and I will check with Israel to be sure.

Hi jond, I have Focal L & R Utopia Be speakers, 90db sensitivity and 8 ohm impedance, minimum 3.4 ohms. Although not sure how well it would match with my speakers I am somewhat interested in the Music Reference RM-200 Mk. 2 as a possible contender. I don't have a large budget maybe around 5k, and no problem with used gear. Thanks for any thoughts.
