Thinking of adding a subwoofer for more bass.

Indeed. If bass slam and/or dynamics is what you're looking for, try different speakers and/or different (less compressed) music.

Better advice has never been given.

Get a decent sub and see how you like it. It is definately worth testing. A good subs can be had for under $500 as well, such as ones from Hsu or SVS. Experimenting is a good thing.

Bob,

Glad you approve of the advice, but it's usually an excersize in frustration! Utilizing PEQ below 200hz is the only effective method I've found to consistently and EFFECTIVELY "tweak away" the bass response issues that Marantz describes. There may be other approaches, but I couldn't find one for my room. Some folks get lucky with room/speaker mating but others (like me) are stuck with hostile environments.

In reply to your comments I am reading the 37 Hz right off the specifications. My main concern was that if the output of my system was not generating the low frequency the sub woofer would not make enough difference. I guess I will have to experiment. I have been looking at the HSU units, and they have gotten great reviews.

One other solution I have thought of is tube rolling. I have heard the Svetlana winged C's are really great tubes and they should be an improvement over the stock Cayins. FYI I play records and CDs. Hate compressed music. Most likely I am going to try the woofer first because I wasn't not too-impressed when I changed out my speaker cables.

Thanks for your help!
