Flat speaker sound/preamp the culprit?/external EQ needed?


Hi, I have a Rogue Audio tube amp, which I love, a U-Turn turntable and an NAD phono preamp. Here's my issue: on many recordings the bass can really drown out the rest of the record. In general things sound muddy. When I plug my iPhone directly into the amp, I dont have this problem. So I think the premp is the culprit. (It has no EQ controls.) Can someone recommend a reasonably priced solution to this? An external EQ? Something else? (Someone recommended a Schiit Loki.) Many thanks in advance!

You can try moving your speakers out from the back wall it will lower the bass and open the sound stage 
The iPhone is not powerful enough to drive the amp 
 Rogue Audio make some good stuff I had a Cronus Mag and have been to the factory they are a great bunch of guys too 
Which preamp do you have

that is a phono pre amp what is your pre amp that controls the volume and input 
the Rogue RP1 pre amp would be a good match 
Rogue Audio Tempest is a integrated Amp have you tried the phono input without phono pre amp it will run a MM
