If you have a very good pre amplifier it will pass all the information from your source equip such as CD to power amplifier without adding any character or losing any information. If not, it is just headache.
But, it will be different story if you need treble, base control, loudness. If you are a Vinyl lover and make things simple from phone EQ or stepup transformer etc...that will be another story.
A similar discussion just went on over here: conventional passive preamp thinking may be wrong - Transcendent Sound Message Board

A passive volume control can work if properly designed, implemented and buffered. I have seem some that cost $1000s.

With all this equipment I've amassed over the passed year, my Grounded Grid preamp is the understated jewel of my system.
