Know before you buy
The SX-1000R is a high-power monoblock, making it an excellent choice for demanding, low-impedance speakers that require significant current to perform at their best. It excels with large floor-standing speakers that need tight control over their woofers.
Yes, it pairs very well with tube preamplifiers. The amplifier's high input impedance ensures it won't strain your preamp, allowing you to enjoy the harmonic richness of tubes while maintaining the speed and authority of a solid-state power stage.
No, the SX-1000R utilizes Class D technology, which is highly efficient. It runs significantly cooler than traditional Class A or A/B amplifiers, meaning you don't need to worry about excessive heat buildup in your equipment rack.
Absolutely. Because it is a monoblock design, you can easily add individual units to power each channel of your surround sound system. Its compact footprint also makes it easier to integrate multiple units into a standard rack compared to massive multi-channel amplifiers.
A monoblock design provides complete channel separation, which eliminates crosstalk and ensures that the power supply for one channel never impacts the performance of the other. This results in a more precise soundstage and improved imaging.
