I am a huge fan of analog and I have a really good digital setup as well. I like the digital, but not as much as my analog. Having said that, though, I have spent a lot of time and money getting my analog setup to sound as good as it does.
I have no doubt you should be able to get an analog setup to meet or exceed your digital, but how much would you have to spend in terms of time and money is hard to know.
I am not familiar with your particular setup, so I do not know what the potential for it is, or if you would need to replace some or all of it.
It also seems to me that maybe you prefer the sound of digital. Since you are so happy with the sound of your digital rig, it may not be worth your efforts.
