Muffled vocals


I have positioned my speakers every way imaginable and I just can't get the vocals the way I want. They're centered, but they seem like they're in the background.  I want them more up front.  I've tried various toeing methods and room treatment but they still seem a little muffled.  My equipment: Lyngdorf TDAI-2200 integrated, Marantz CD6006, Tyler Acoustics D-20, Anti-Cables, Audioquest digital cable.  I know the recording can have a lot to do with it, but Steely Dan's Aja is known for the recording quality and Donald Fagen is in the back.  My terminology no doubt betrays my lack of sophistication when it come to audio, but I know something's not right.  Any suggestions?

Here is a question since the Lyngdorf does room corrections might something be set in a way that's pushing the vocals back? And is the Marantz connected to the Lyngdorf's digital or analog inputs?
Digital is still in second place for realism when compared to a good LP playback system! Check out Fremer's Analog Planet site! I am glad I held onto my analog gear and LP's when everybody was ditching theirs! "Perfect Sound Forever!" - NOT!
The venerable Altec Valencia's have a mid-range presence lacking in most contemporary (and touted!) speakers! They certainly can bring the performers right into your listening room!
Are you using the digital out of your cdp or the analog outs into the Lyngdorf?
