Sanders sound systems preamplifier

Swapped new sanders, took out old onkyo.  Now there's radio stations and constant tapping noise from tweeters, wtf is going on in this house ???   Anyone have any thoughts to this noise I'm g eating? I'm out of my mind, unplugged every damn thing 100 times, no static, I plug in preamps, and I get machine gun snare drum, constant, and now I can hear radio stations from tweeters 

I think i figured it.   Shi$$y cables gave radio station int. Pioneer dv48 light static.   Still static. Will continue to pull components/cables tkl infigue this out.  Driving me nuts

pio dvd is region free 

Anyone notice lack of bass with sanders preamp??????

like it disappeared, wtf. Over speakers closer to wall, a wee better, but still........seems lacking. 

Will cables help? A good CD player?  

I h age early 90's audioquest Quartz, and using an old Sony cd/dvd player

No lack of bass with my Innersound iControl Pre. The bass is deep, tight, fast and the timber is spot on! Keep trying to figure out your problem. I would suggest a dedicated line. Make sure you do not have any major appliances on that line or florescent lights.

This is what I have.   New furman power strip ac cond/surge, only for other components, amps plugged into wall.  McCormack dna750's, sanders preamp. Audioquest Quartz 1m from preamp to amp.  Using toshiba sd4000 as CD player, with audioquest turquoise. 

Pair of energy rc-70's hooked up with real 8 awg wire via fake nakamichi locking bananas, same as all the other nak bananas out there, only a 10mm hole to put the thick 8 awg wire. 

Also tried ipod, bass is very null, it's there, but it is lost in the music, the treble/mids are very in front of everything with cd and iPod

could the pre be this thin? As. Mentioned wi th my onkyo p-308 from 1989 I have great bass.  I replace with sanders, and the bass is weak.
