A question about pioneer spec-1


I have a pioneer spec-1 preamp.
Should I buy a power amplifier to drive my headphone with spec-1?

If I have buy one, any power amps are fine to be matched with spec-1? Should I buy spec-2 or spec-4?

Also I'm a bit confused to connect my rig to preamp.
My rig is began from my laptop -> dac -> preamp -> poweramp
Is the process correct?

Please anybody helps me out.
