Clever Little Clock - high-end audio insanity?

I know some blond's that have an "illusion" of a brain.

Two blonds walk into a building. You would think the second one would have noticed.

Hee hee! The second blonde was an audiophile ;^)

Was the first blonde a woman, and the second a man? Or was this a trick question, and they were both men?

Well, how many blonde woman audiophiles do you know? Actually, not only was the blonde an audiophile and a man, he was the same man -- unfortunately though, he wasn't carrying his CLC on his person, and therefore experienced some temporal dislocation which resulted in his walking into the building a second time...

Oh, and all this time I thought it was done with mirrors...
