Know before you buy
A monoblock design houses each channel in its own dedicated chassis with its own power supply. This eliminates crosstalk between channels, resulting in superior stereo separation, a wider soundstage, and more precise imaging.
Class A operation keeps the output transistors fully conductive at all times, which eliminates switching distortion. This results in a highly linear, natural, and detailed sound profile that is often described as having a liquid, tube-like musicality.
While 60 watts may seem modest on paper, the XA60.8 delivers high-current Class A power that is significantly more capable than typical amplifier ratings suggest. It will comfortably drive most high-end speakers, though it is best suited for designs with moderate to high sensitivity.
Yes, because they operate in pure Class A, these amplifiers generate a significant amount of heat. They are equipped with large heat sinks for thermal management, so you must ensure they are placed in a well-ventilated area with plenty of clearance on all sides.
The XA60.8 is designed with balanced XLR inputs for optimal noise rejection and signal integrity. If your preamplifier only has RCA outputs, you will need a high-quality RCA-to-XLR adapter or cable to connect them.
The XA60.8 is built with premium components and a robust power supply, making it exceptionally reliable and virtually maintenance-free. Aside from ensuring proper ventilation to manage heat, there are no tubes to replace or regular adjustments required.
