How to remove harshness from my digital gear

Even with an analog front end, there is such a thing as a harsh cartridge. Analog or digital, start at the very source of the sound and go from there by isolating and substituting until you have identified the harsh contribution to your sound.

Enjoy the music.

I know I have a great deal of ground loop hum (audible from the speakers at all times). How do i get rid of it?

Geoff - the CD sounds thin due to jitter from the badly formed pits. Rip the CD with dbpoweramp to .wave file and then rewrite onto a CDROM using a good writer and you will experience lower jitter. Reclock the CD transport and you will experience even lower jitter.

IME, its easier and less expensive to go the computer audio route to achieve lower jitter than CD players.

Robsker - there are two things you can do to eliminate hum, short of buying different components:

1) try changing the AC power for each component. IF they are all on the same circuit, this should minimize it, but may not stop it. Different phases from the panel will definitely cause hum. Lots of separate power feeds to a single system is usually disastrous.

2) Get a transformer buffer/isolator like the Final Drive or a TVC like the Music First to replace your preamp. This will break some ground loops.

Other things that can cause hum are: direct connection of a cable TV system to your system ground. Buy a Jensen RF isolator and insert in the CATV cable to stop this. Some components just have screwy earth grounding, so hum can be impossible to eliminate on these....

FWIW, I never play CDs directly on my system anymore. THey get ripped to music server and played from there using Squeezebox or similar network player with external DAC. This approach takes a lot of the guesswork and uncertainties associated with more error prone real time reading of data on an optical disk and the potential effect of this on jitter, etc. out of the process. Not to say that jitter might not be lowered even further in each case resulting in better clarity, resolution etc., , but I find this puts things in a pretty good place soundwise in terms of no inherent harshness in general. Just my experience.....

Also its worth saying that there will ALWAYS be some CD recordings that are inherently bright due to the way they are produced and mastered. Many newer rock/pop "loudness wars" type recordings come off relatively harsh compared to others. Many others that are mastered and produced better do not. More loudness generally means more of whatever there is in the recording to start with, good or bad. When the waveform peaks get clipped in the process, which is not uncommon in many modern pop/rock recordings, well, there you go, it is what it is and best you can do is damage control.
