you get the sub audible bass frequencies

Purely out of curiosity: if they're sub audible, how do you know they're there and what's generating them?

Unless I missed it, you haven’t said why you want to put a preamp between your DAC and your power amplifier.  Are you trying to change your SQ in some way?  I know the Junior has a knob on the front - is it not a volume control?
 

You might want to invest $58 in a Nobsound balanced zero gain “preamp” from Douk Audio before putting a lot more money into something you may not need. It has a decent Alps volume pot and 2 sets of ins & outs (XLR and RCA).  I think it’s a great little item when you need a volume control stage and nothing else.  Some reviews say a buffer stage like this improves  SQ, although I haven’t found this to be the case with any system I’ve ever had.
