Why do HDDAP remaster existing material?

Quite simply, in my case I have a vast amount of CDs; most which I considered, unlistenable, they sound that poor.

Why is this? Because I get listening fatigue, when I listen with a good amplifier and full range speakers.

Unfortunately, once the deficiencies of Redbook (this is the CD standard) sound are pointed out, then these anomalies become quite obvious. Even using an upsampling DAC, which does reduce the issue, it is still a genuine annoyance to me.

Because of this I started to look for solutions, the first one was to record CDs onto reel to reel tape, this sounded great with the early CDs (although not practical, as it appeared to bring out more detail and muscal timing.

However once the loundness war (https://en.wikipedia.org/wiki/Loudness_war) commenced and limiting and compression become standard practice then even recording onto and playing back from tape, could not substantially improve matters as it did before.

I then spent a lot of time working with Wormwood (of HDDAP) to see if we could remove the sound of heavily compressed mastering and also try and squeeze more detail from CD.

Whilst I was also investigating this process, I started to develop a process which aimed to create a sound similar to mastertape, from a CD. Very useful if the origina master has been destroyed, for example.

This is in another article called the SpEAR and dLeAR processes.
