New preamp, loss of low freq.?

Hooked up new preamp, and I lost what I think is some low freq slam. Reasoning behind this?
i have been rewarded with the best cleanest, accurate midrange/highs I have ever heard, but did lose some low frequencies.      Normal?  

Sanders preamplifier is the new addition. 

Should i I hook up my equalizer to  smooth out, and add some low freq. 

it it is recording dependent, I still feel I lost some bass when sanders is in the mix. 

Not complaining, this has completely opened up my energy rc-70's, I have never heard these sound so loud, so clear before.   It's I feel I lost a few octaves in the lower register. 

Better? Leave it, I can definitely get used to this sound, as before it was a small bit boomy, maybe I just need time to adjust, and to let the pre warm up for a couple weeks. 

thoughts, recommendations, tweaks? I suppose I could move the speakers a little closer to the wall, this may add a little more bass.

lowrider57 hi.

Just one example, just about every piece of gear cdp, dacs, preamp and amps made by Krell is dc coupled. And there are many many others ss brands that do too. 

Tubes are a different story "most" tubes amps, cdp, dacs and preamps are have massive dc offset, to block this they either have capacitor coupling or are transformer coupled.

To me it looks like preamp does not provide sufficient output to the poweramp input. It also has user-adjustable gain.
Get the right gain settings and you're happy camper.

If he can get the levels he wants to listen at, there is no problem with "output" voltage from the preamp.

I get my volume, and then some, as well as bass, and everything I need!!! I have zero more to say about the bass, sound of my system. I have found my last amp, preamp for my ref system. Cables and CD player are on Santa's list, and time to re-import all 3000+ cd's in lossless.  I wish those 1TB iPods weren't a f'n thousand dollars though, would love to have that, using iPod is so convenient through stereo.
