First of all, I'm assuming you mean any digitized audio is lossy
Actually though, it is possible to sample analog signals to digital, and then recover the analog input perfectly. This is tough (at least for me) to conceptualize, but those EE profs really seemed to believe the Nyquist-Shannon sampling theorem and at some point I was convinced ;-)
The basic idea is that if the sampling frequency is double the frequency of the analog input, then there is no loss of signal.
I think it's the average human that can hear from 20-20KHz. So, CD's 44.1KHz sampling frequency is 2x 20KHz + a little extra.
With my admittedly non-professional understanding level, I would suggest that more "loss" occurs during the capture of the analog signal(mics and recording equipment), than during the actual conversion from that analog signal to a 96KHz 24bit sample. And then of course, before a comparison can then be made between a live performance and a replayed digital version, there is the reproduction equipment quality to take into account (amps, speakers, etc)...
