Speakers or Amplifier

Stringreen,

I would love to have more bass...not just feel it, but hear it. I currently have them 48" from the front wall. I love the openness, imaging, soundstaging(depth and width), mids and highs are wonderful. I'm hesitant to move them closer to the front wall, because I don't want to sacrifice everything else. Any suggestions are appreciated.

Why not go with a set of subwoofers? SVS, JL, Martin Logan ... just to name a few have excellent products. Make sure that it's a sealed unit with adequate power. Subs have come a long way and may really improve even a very nice system such as yours.

Just a thought, but why not try different speaker cables. I am not discounting yours, but sometimes a different cable cab make a big difference in sound presentation. Try the lending library at the Cable Company, provided that 8 feet will work for you. I think all their speaker cables are about 8 feet in length.
Again just a thought.

Brauser,
In general I don't like subwoofers, but I did send an email to Bricasti to find out if I could connect a JL F112 subwoofer through my M1 DAC.

Theo,
I've tried several speaker cables(Transparent, Cardas, Shunyata)and thought the WireWorld Silver 7 was the most balanced.

Not familiar with your wires either, but as interconnects and cables can make a significant contribution to what level of tonal color is revealed I'd probably start there too. I'd demo a full loom Acoustic Zen as I know them to be very organic sounding without sacrificing things like detail and soundstaging that seem to be important to you. If that doesn't work I might try to audition a good preamp. Not sure how the Bricasti does as a pre, but some systems seem to benefit significantly by using a standalone preamplifier. If you're not tube averse maybe a VAC or ARC pre, and solid state maybe Pass Labs, Boulder, Vitus, Sim Audio. Hope this helps, and best of luck.
