What happened with the BASS? MC352/C42/B&WN803

Hi.. last saturday, I took home a Mcintosh C42 to replace the Onkyo919 (as pre-amp). I can truely feel HUGE improvement with sounds stage, highs, superb mid-range, much lower background noise, and much more musical. However, bass seems to be weaken and less dynamic. although I haven't play much with the Equalizer yet. Can someone tell me why. Thanks!

My current set up:

B&W Natilus 803
Mcintosh MC352
Mcintosh C42
REGA Planet 2000
Richard Gray 400s
MIT Shortgun IC and speaker cables.

All the connections should be fine. I only change the IC from cd to pre and to amp.

It the C42 brand new (or almost new)?? You should leave it on with a signal going through it for at least a week to let it break-in some.

You should be on the 4 ohm taps on the MC352 since the 803s are 4 ohms. You might also want take the bi wire straps off the back of the speakers and connect the mid highs to the 2 ohm taps and the woofers to the 4 ohm taps. Just use some simple cable like 12 gage for the experiment and use it on the base connection.

Sugarbrie, the C42 is brand new. I am not sure if I want to leave it on all the time. I will be a little more patient letting it break-in.
Rontube, I am currently using the 8 ohm on the MC352. The 803 are 8 ohms. However, Mcintosh did saids to use the 4 ohm if I upgrade my N803 to N802. splitting the speaker cables to 2 and 4 ohm seems aggressive to me.
Thanks for your responses.

Dumb question time! Are you saying that your new Mac pre is defficient in the bass in an absolute sense or only in comparison to the Onkyo? If the latter, is it possible that the Onkyo was just a bit over ripe and you are now hearing a more accurate bass?
