For many today Digital is all that is known, it is a bit sad many have not experienced the other or possibly better but what is best ? There is no right or wrong , just good, better, possibly best and it depends on so many other factors, speakers, environment and you.
Music should be appreciated however it comes to you and when we listen more, its then if we have the means, by hook or by crook, we seek better and this is where the quality dealer can assist you hear the difference. Once you do,, there is no going back to the Hi-Fi in a box.
For many we simply bundle the above types into Digital, Home Theatre, Solid State and Tube but we do have sub categories and we have products that can integrate such as a Quality Tube Amplifier with a HT By-Pass can appease all the family when integrated into an appropriate home theatre set up. Ones interaction and control varies from user to user and for some of us this control aspect varies the enjoyment tremendously.
We also have within "the Type" do you want Single Ended or Balanced? Some products offer a blend of both and many have a preference or a need to satisfy and a reason why.
