I am looking to get more bass out of my system

The power cord and cone root sounds like the best advice so far . And you won't be messing with other things . You have likely found the best spot for your speakers , moving them back may give you more bass but usually causes more problems than it solves .

Mainsound,

REALLY, REALLY examine your tube compliment in your Jolida amp and your Cary amp AFTER you have determined that you are tubed correctly in your CD player. And do that ONLY after you have remedied using a splitter in line to connect your CD player to BOTH amps, which would never be advisable for optimal performance. I'm not saying that stacking your speakers wouldn't be an interesting experiment, or buying another subwoofer nor am I saying that buying a couple of garden hose power cables wouldn't improve your setup (I have a few of those myself).

No one has asked the important questions, of which I am quite surprised. What tubes are you currently running in your amps? Is your Cary direct coupled? Is the bass performance equally weak on both amps?

Please, save yourself some time and money, the main problem is likely your source but until you get that right, you'll be wasting your time dinking around downstream.

Chorus II's and to a slightly lesser extent Chorus I's put out copious amounts of bass with low to medium power amplifiers. As suggested, try corner placement and make sure your sub has the proper phase setting so there are no cancellation issues.

Thanks everyone for the sage advice. Let me say I have rolled numerous tubes and have a healthly compliment of vintage tubes which I feel give a beautiful sound. Speaker placement is stacked and 8 inches from the wall. All interconnects and power cords have been upgraded and I am happy with they're impact on my system. As Bill has pointed out the chorus's do put out copious amounts of bass when asked to do so, but I would like to hear a little more bass all the time. Does anyone think a graphic equalizer would help and if so what would be the best way to wire into the system? Thanks again for your help and insights...Pete

If you are looking for more bass than is say "natural" to certain recordings, then a graphic or parametric equalizer is a reasonable solution.

If it were me, these days, I would look to do the equalizing in the digital rather than analogue domain if possible in that digital lends itself to custom signal processing needs/desires much better than analogue.
