From the website:
Transporter:
Balanced Analog Outputs
* Connectors: XLR gold-plated
* Level: 3Vrms (8.5Vpp)
* Impedance: 100 Ohms
* Attenuation: Fixed -0dB
Unbalanced Analog Outputs
* Connectors: RCA gold-plated
* Level: 2Vrms (5.7Vpp)
* Impedance 100 Ohm (at -0dB)
* Attenuation: Selectable -0, -10, -20, -30dB
SB3:
Analog RCA outputs
* High fidelity Burr-Brown™ 24-bit DAC
* Two dedicated linear power regulators for DAC and line-out stages
* Full 6.0Vpp line-level signals
* Signal-to-noise ratio: over 100dB
* Total harmonic distortion (THD+N): less than -93.5dB (0.002%)
So, if you're using unbalanced out on the Transporter, then it is
slightly quieter than the SB3 (5.7Vpp vs. 6.0Vpp).
