Denon DL-103 and Audio Note AN-S2 SUT problem


Hi all. 

So with high hopes of glorious vinyl sound I purchased the Audio Note M6 phono and the AN S-2 L SUT. The pair replaced my M3 Line and a Lehman Black cube phono stage head amp.
Well it didn't work. It sounds like my laptop speakers. No bass, very tinny and almost no gain. Not even listenable.
Is the AN S-2 SUT that poor a match for the Denon DL-103? I am pretty sure I have read that others have used this combination successfully. Even my local dealer said it would be a good match.

Is there a problem with the SUT maybe? 

I am quite disappointed to say the least.

Thanks for any help.

I don't understand your post. 

The M6 phono is a pre amp with a MM phono stage built in. Audio Note don't make an MC phono stage for their pre amps. That's why they have SUT's

The M3 pre amp doesn't have a phono stage.
