After some upgrades, where is the weak link

While your system may not be technically in the "mega dollar" range , it is close enough for all but the extremely wealthy. There is no glaring weak point as far as your components or cabling goes. It's possible that the speaker cables or some other cable in your loom may not be a synergistic match for your gear but I think the real weak link in your system may be speaker placement, or possibly your room. Getting loudspeakers, especially full or near full range ones to produce satisfying bass can be a daunting, frustrating and time consuming exercise at best. Even after hours of trial and error, moving around large heavy enclosures in small increments, it is ultimately sometimes an exercise in futility, as some speakers just don't match certain rooms. Acoustical treatments can be very helpful if applied correctly, but the greatest gains are often to be had with placement experimentation. I tinkered with placement for my current speakers for almost a year before finally being satisfied that I had achieved the best possible integration of my speakers in my room. Just be sure to mark the location of your speakers current placement, in case a new positioning scheme is not to your liking and you want to return the speakers to their previous spots. The dealer I frequent local to me is a Revel dealer and I have heard the Salons many times and know they are capable of prodigious low frequency output and explosive dynamics without the aid of a subwoofer.

Rcrerar,

Thanks for the response...the speakers are probably in their final spot, and I'll live with the bottom end from the sub. Will eventually add another one--thinking about a transport to replace the 390s next--MBL probably.

How about a good record player? That will give you something to occupy your spare time. I have no problem with CDs, but I think anyone looking for audio satisfaction should also consider vinyl to compliment their CD collection. You may realize that that "extra" thing you were looking for was not a different transport, etc.

Wow! Nice system. If you go to Decware website, Steve has written many papers on room acoustics. He states that 50% of sound is from components and the other 50% is the room that they are in and how they interact together. You might have standing bass waves that are causing a null in the listening position.
Have you listened from different areas to see if the bass is stronger than it is when you are in the sweet spot? Try it and see, if the bass is stronger in a different seat then maybe some bass traps would help.

Of course, always check polarity of speaker connections if the bass is not happening as it should.

Speaker placement is the next most likely culprit.

And of course adding a sub seldom hurts with most speakers if adjusted to blend in properly..
