New NAD 326 BEE Owner -Disappointed Help

I've browsed the used gear for sale at the Audiogon site, but never posted a new topic. I'll be brief.

I bought an NAD 326 BEE in late 2009 from an authorized dealer. I just got around to hooking it up, since the controls on my NAD 3140 need cleaning. Problem is...I hate it!

I LIKE the sound of the 3140. Sure, the sound is a bit muddy, but I like warmth, so I've put up with it's shortcomings. But the 326 BEE is wimpy. I've got the bass set at about "7" on a 0-10 scale. At this setting, it's comparable to around a "3-4" setting on the 3140. The bass range on the 326 BEE is really disappointing.

Here's my very humble set-up:

-NAD 315 BEE CD player
-Technics SL 1200 turntable w/Shure M97 XE cart
-B & W 602 S3
-NAD 326BEE w/NAD PP2 phono preamp, (sure the Jolida JD 9A would be nice. But it won't solve the amp problem).

So, my question to the forum is, should I keep the 326 and try a pre-amp, or just ditch it for something else? Maybe a Parasound amp? I like really warm, tubey sound, but I want to stick with an integrated amp.

Thanks, John
