In theory, yes! digital amp will be more and more common as they are cheaper to make. unign can be esaily shaped by programming rather than hardware. But it stops there. Our ears are not evoluted to take in the digital stream. This will never happen! A digital-to-analog(DAC) must be there to convert the digital stream into sound. This starts the problem.
If you are a serious audiophile, you should agree that in the same price class. Current DAC still chases behind analog LP. DAC output is small signal in terms of mA. When coming to amplification, you shall need a ADC of capable to convert vey steep power rise to meet dynamic needs. Still now, as far as I know, no such ADC device is available. Digital amplification is still a long way to go.
