Energy Veritas 2.1 sound too lean

I recently purchased a pair of Veritas 2.1 monitors and have reached the recommended 100 hour break-in period.
Overall the speakers sound great except for male vocalists who sound quite lean and slightly to the rear of the soundstage. I'm playing CD's through my Creek integrated amp sound which normally sounds fuller and more robust on my old mini-monitors. I can't seem to get the timbre and/or harmonics that I think these speakers should reproduce with male voices.
Anyone else have a similar problem? Possible solutions?
