Pros: Good value, well built, provide tangible results
Cons: The units are a little long and may cause some issues in some installations.
A common issue with connecting modern sources is the output level they expect all components to accept. Since the age of the CD player, most modern sources output around 2 volts, while both power and integrated amplifiers typically have a much lower input sensitivity of between 100-500mV. The result being you have limited range of control on the volume pot and you are operating in the lower portion of a volume controls range, which is typically where channel imbalances occur. I found myself in this exact situation when using my Audio-GD Compass 2 as a DAC/Pre-amplifier to feed a Cyrus Power Amplifier in order to power my HE500. The Compass 2 has a variable...(read more)
