Know before you buy
The D500 MKIIs are designed to handle demanding loads with ease. Their high current output and low output impedance make them an excellent match for speakers that are known to be difficult to drive or have complex impedance dips.
While the amplifiers feature both balanced (XLR) and single-ended (RCA) inputs, balanced connections are generally preferred to minimize noise over longer cable runs. However, you can use either depending on the output capabilities of your preamplifier.
Like many high-end audio components, the internal capacitors and circuitry in the D500 MKII require time to settle. You should expect the sound to reach its full, neutral potential after about 2 to 3 days of continuous operation.
Yes. The D500 MKIIs feature high gain, which allows them to work effectively with preamplifiers that have lower output voltages, ensuring you can achieve sufficient volume levels without straining your system.
Each unit measures 8.5 inches wide, 3 inches high, and 10 inches deep. Because they are monoblocks, you will need enough shelf space to place them individually, ideally close to your speakers to keep speaker cable runs short.
These monoblocks utilize a custom Class D design that offers the efficiency and power delivery of modern switching technology without the typical sonic harshness. They provide a neutral, controlled presentation that avoids the heat and bulk of traditional Class A designs while maintaining excellent bass authority.
