The rule of thumb is the input impedance of the amp should be at least 10 times the output impedance of the preamp!
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.
