cd plays without preamp

OK so I just get my new Cambridge Audio 640 cd player shipped, I hook it up to replace my old unit and turn on CD player listening to great music and realize I forgot to turn on my preamp , only the amp was on. meanwhile I was adjusting the volume and tone controls and they were working ALL with the preamp off. Can someone explain this to me. The equipment besides the CD is ST-70 triode/ pentode amp by Bob Latino, Dynaco Pat5 bifet preamp,(which will be replaced in a few days shipping with a Cary) and a pair of Klipsch (Crite) Cornwalls. The Cambridge by the way is a very nice sounding CD player for the modest system

Alright, I thought I could get an electronic explanation, sorry I asked, I'll know better next time. Save the sarcasm for your girlfriends

There are tone controls on the preamp, more importantly the speakers get wired to the preamp, which I use for switching different sets of speakers in different rooms ( i.e. A speakers or B speakers along with A+B). This I coud understand the signals ran through the preamp, but how I could use the volume and tone controls at the same time with it turned off. I did not try unplugging the preamp because I now have my new preamp set up ( which does not have speakers wires to it as the Dynaco did ). I will have to go back and re- do everything to check if in fact the same thing will happen with the preamp unplugged. The volume control was definately in the same postion for the same volume as if it were turned on.

Kijanki, actually I used the Spare, not the tape out for the CD, as it obviously didn't have a CD option back then. When I have some time, I'll try to hook it back up, but right now with a new Cary preamp, I can't bring myself to disconnect right now, thanks for your help. Rich
