 I made a previous post about a budget NAD integrated amp, and the C326BEE got a hearty recommendation. As I began looking preowned I notice the Marantz PM6006. They are similar budget amps. How do they compare? Thank you

 I have the Marantz PM8004. Out of the box it had an annoyingly soft top end. But otherwise it has REALLY good bones. The TRI level controls are great and don't impact the sound. It has exceptional tone that is far better than the NAD C326BEE. But I kept shelving the Marantz because of the soft top end.

Matched with the Audio Monitors, it could be overly soft. Especially for TV use.

If it uses the same circuit layout as my Marantz PM8004 there is a fix that would make that amp into a "great" amp. I tinkered with the PM8004 for years. Turns out that the spreader bias circuit uses a thermal balance capacitor. It's a polar cap that connects between the + and - legs. It was however acting as a bypass cap and causing all the rolloff. Simply replacing this cap with a film cap literally changed this amp from one of my trash amps to one that I now use in my main system at times.

If you're going to use it with the Klipsch speakers you may be OK. the MA's maybe a little too soft. If you're good with a soldering iron and can tweak, make sure the two PM versions share the same circuit layout and that tweak will take 10 minutes to do.
