My experience with computer audio is very different to yours. I have a $20k analog/digital system and the results via TT and computer audio are very good IMHO. I am extremely happy with this system and have no plans to upgrade, even though the speakers are 40 year old refurbished Gale GS401A's. See my previous post on this system:
