Newbie want to improve what I have

foxton- I had an M33 and loved it, just didn’t have the free time to listen as much as I liked, so I sold it at an only $500.00 loss compared to what I paid for it.  I now have the C700 I got open box for a grand, love the sound on it, too.  If you go into the tone controls and bump the bass up one or two notches you might find you have just the sound you want, or pay the extra hundred bucks and get the full Dirac Live room correction that will correct down into the bass regions and get what you’re looking for through that.  A subwoofer might help, too.  I know there’s naysayers who think tone controls should never be used, don’t listen to them.  I will say this though, physically correcting your room can have a profound effect, it did in mine.

Wow, I wish that was my starter system.....but many people are correct, system matching is critical but I don't know your components Only 2 suggestions:

(1) Get some room treatments, others know way more about that than I do. But, a heavy area rug, think curtains, and a few panels from GIK Acoustics worked magic

(2) As some have mentioned, run your amplification directly from the outlet.....through a power conditioner/protector is no bueno. Better yet, run a dedicated line (or two): dedicated line and audiophile outlet (PS Audio, Furutech, etc) and run through that

I think of it this way. First you need the dimensions of your room. Then you decide where to place the speakers - usually at the short end, playing along the length of the room. Then you investigate and test speakers and amps to get the best match room - speakers - amp. If you have persistent problems - maybe not, if you have a large room, you treat it a bit (not too much).
