When your preamp doesn't match your amp


From what I've gathered, there are some great amps (e.g. Pass' Aleph) which are quite finicky about the preamp they're connected with. I understand this is typically tied to an impedance mismatch, but what I don't understand is what does this *sound* like?

Could someone describe the symptoms of a poor preamp/amp connection?

Thanks in advance,

Normally the amps will sound slow, not really dull, but slow and they have no air in the high frequencies. Unforutnately you will only notice it, when you know the reproduction when everything is right.
