Cory, I'm not sure I understand what you are asking. Add volume and depth compared to what. Are you asking if it will play loud enough? As for depth, you might percieve more depth in a recording because passives reveal lots of details and "depth" can be part of subtle cues in the recording. What you need to know is the output voltage of your source and the input sensitivity of your amp. Another issue would be the input impedance of the amp which is likely fine as most tube amps of high input impedance.
