Question about sound stage

In every recording, the soundstage sounds skewed to the right in my room.  I can hear musical instruments to the left, but the singer is ALWAYS on the right.  Is that normal or is there something likely going on with my speaker placement or room setup?  FYI, I am audio newbie.  My setup is as follows: Franco Serblin Accordo Essence speakers; Luxman 590axii integrated amp; Antipodes K40 music server; Weiss DAC 502.  Silversmith ribbon cables.  

My audio environment is less than ideal to say the least.  My speakers face my rather large office desk and only one speaker is optimally spaced from the wall.  There is no other way to arrange my office, so it is what it is.  I can always include a picture of those who are curious or think it would be helpful.  Also, I haven't gotten around to learning how to use the Weiss's DSP room correction function yet, so perhaps that would help.

Thanks.
