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.

Please give it 200 hours. Keep it playing and you will be happy. All gear needs to run in. That is the "issue".

Georgelofi;

 prior to the sanders I was using an onkyo p-308 from 1989. 
Also, a B&K pro 10 mc.   The onkyo is adding low freq, the B&K is closer in sound to the sanders I think,.............


will ill try to breathe, promise, I've just had such bad luck over the years, equipment, a job I wouldn't wish on my enemies, and other stuff as well. Sigh- the preamp does not have a sub output, I hate mucking around with eq's. I still have my old onkyo eq from. The early 90's, pristine shape, maybe hook it up one night and see what can be done.   

Oh boy, .

As far as the missing bass.   I am using audioquest Quartz cables from 1991 or a1990, I'm sure things have changed since then. I will mess around with cables, and speaker wires also.   Hopefully I can get back a small portion of my low end, then all will be prefect. 

 It's 2:30 now, time for a Negro Modelo !!!!  Have a good evening everyone.

Just looked at the Onkyo P-308 and it has a switch, similar to a loudness switch but without the HF boost, it only boosts from 200zh down. Maybe you used to have this switch on when you used to listen to it, and your Sanders pre is not going to give that.? Anyway you've now learnt something about capacitor coupled outputs.

From Onkyo:

"A contra-bass switch is added for those in need of more guts down below but only at 200Hz."
