Hi Leo:

Welcome aboard, if this Technics is your first it will take awhile to get familiar with it. Give it time, I'm still finding new things and re-discovering old ones.

I have a PR804 and still own a PR900.

The most popular and most sells are the KN models vs the PR's. With this in mind, you will find more support, and topics supporting the KN models. It's just sure numbers of KN's vs PR's that causes this.

The people here on this forum are friendly, but do speak their mind, and will gladly help with any questions you may have. The KN6000/6500/7000 are similiar in a lot ways to the PR604/804, but on the other hand different too.

If you have any particular questions in mind about the PR604 ask away.

Anthony
