...The big question is do you like what you hear? If so f@#k the specs and love the music. ...
Just thought I would mention that I measured some different expensive RCA plugs for capacitance,
Hi Roger,Sorry to throw one from left field but source impedance as high as even 1K can seriously degrade both the PSRR of the amplifier and it's THD. I recommend using max 10K stepped attenuator/pot and finding the typical user setting , say 800 ohms, subtracting that from the 1K input filter on my amps which are balanced with the feedback R. This ensures the PSRR of the amplifier is maintained (so you are not listening to PS artefacts -ugh!) and THD is as spec'd, both in magnitude and makeup.Cheers,greg
Barry,Now the math.... The 3db down point will be F=1/6.3xRxC, where R is the worst case outp ...
