Vic, I am very interested in great sound. I am very appreciative that audiophiles are pioneering and advancing computer audio,and will probably someday go to computer audio myself. I do use lossless iTunes for on the road and to deliver meditation workshops, but right now these are some of my objections.
1. Currently I enjoy simplicity. I have an Ayon CD5's which has transport, Dac, and Preamp all-in-one, saving multiple PC's and IC's and resulting, with other strategies, in a dead quiet, ultra clean background.
2 I often spend 12 hours a day on computer for work and find it more relaxing and enjoyable to be away from computers and feel and see the physical media when listening to music.
3. The thought of transferring 3,000 discs to storage is daunting and I have never seen a drive that was not subject to failure and easy theft.I have experienced trouble with backups when they were eventually needed.
4. I am in a 3mbs zone where it takes forever to transfer large files such as High Res. Re-buying all of my favorites as downloads and having restricted access to new music, compared to the availability on CD at this time is not appealing.
5. Computer tech is changing so fast and there are so many many options that for the uninitiated it is a highly complex and moving target with a whole new vocabulary that is also intimidating - and for me the hobby is already obsessive enough!
6. It is highly likely that computer audio will be substantially cheaper, better, and simpler in a year or two and new formats such as DSD and Blue Ray audio and BD CD's may dictate different approaches.
I hope this helps you understand why some intelligent music lovers might be reluctant to jump on computer audio at this time, even with the promise of audio nirvana.
