I am frustrated with the sound from my DAC


My DAC-IT by peachtree audio is sounding harsh in my rig now. I am comparing the sound of it to my Cambridge Audio DAC Magic plus with the two Wofson Chips inside it. The Cambridge Audio sounds good, smooth and nice. Anyone know what is inside the peachtree DAC IT. My Digital source is a cambridge audio DVD player. 540D. My next move will be to use my better sounding ARCAM CD player with the peachtee DAC and see if it is smoother sounding. My amplifier is Cambridge Audio. Sweet sounding one. Not a CX series, but sweet sounding.

According to this Stereophile review, the Peachtree DAC-iT uses
the ESS Sabre24 9023 DAC chip. I briefly owned the DAC-iTx and thought the sound was good but not what I was looking for.

I owned a few Peachtree products and always thought they sounded, well digital to be honest.
Very harsh and sterile.
