amp/Speaker bass output

Both your ARC and Classe' are somewhat lean sounding pieces, which combined with the Apogees, probably really makes this noticeable. You can try to band-aid the system with cabling, but you might be better off assessing what you think is the weakest component and replacing it with something more suitable to the sonics you desire. Adding a subwoofer would make for a better balanced system, but you are now talking about greater complexity, more floor space and having to tinker with blending the sub to the mains. Sean

Were the room treatments installed when you had the old components?

Going to xlr connections may help the macro-dynamics and bass a bit.

Perhaps the easiest route toward some sort of bass satisfaction would be to consider adding the proper subwoofer and subwoofer interconnects. But even then, you may be left wanting.

If you'd prefer to modify what you have, then you probably need to focus on interconnects, speaker cables, and amplification.

For that I'd recommend the Audience AU24 ics and speaker cables and any one of the McCormack DNA-0.5, 1, or 2 REVISION A amps should catapult your sonics and bass regions into a whole nuther league.

The cables and amp suggestion would be my first recommendation because it should easily give you the bass improvements you may be seeking and it should also provide substantial improvements everywhere else. And perhaps for the same price as a good subwoofer and interconnects.

At least with the cables and amp upgrade path, you may also recooperate some of your losses when you sell your older gear.

Also, I am not familiar with your speakers. I'm assuming they are somewhat of a full-range speaker.

Hope this helps,
