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.

I do hate low impedance amps - I have Mcintosh 501's that are 10K and do not work as well with my CJ preamp.  I have a Classe with a 75K and the combination is much more dynamic.

George - good call on the output coupling cap...

So should i return the pre, look for a pre which is more compatable with my amp?  The pre is quite nice, it definitely opens up my speakers quite a lot,!

I do have bass, it just isnt as thick as before this preamp. Definitely some is gone. 

Anything else i can do

The preamp does not have any capacitor in the output circuit. It has a very low output impedance of only 50 ohms, so it will drive an amplifier of extremely low impedance without any problems. What this means is that the preamplifier is not rolling off the low frequencies of your amplifier. The preamplifier has linear frequency response (as do all other quality preamps).

The solution to your problem is to use a DSP (Digital Signal Processor). With one of these, you can adjust the

I suppose if I knew these amps were hard to drive, I would have bought others which are more compatible ,  so I'm stuck, and blew my whole fuc**ing rat hole money which I saved for almost 5   Damn years for new amps, stereo, and I end up buying something which is not compatible with many preamps, because of some impedance output, f'n great, just great. Now I'm stuck with them, goddamnet !!!!!!!!!!!!!!!!!!!!!!!!!!!

nothing has ever gone correctly for me, I buy a new amp, breaks shortly after, preamps, with problems .  I'm just gonna buy a Bose wave, and be done with this whole schlock, impedance, I or, output, capacitors, f this
