My question is.. why do you need to model so many different amps if you are simply playing it through your headphones?
It seems that many people are in love with it. Are all these people paying $200+ for a fancy headphone amp, or does it do something else?
The PX4B and PX3B were a headphone amp, a multi-effects unit, a sampler, a simplistic drum machine, can slow recorded music w/o pitch shifting it, cancel bass frequencies of the original music and act as a 2 channel mixer.
The specs for the PX5D is as follows:
