The updated MK2 versions replace the previous DAC501 and DAC502, improving upon their predecessors with advanced DAC chips and upgraded circuitry. The result is said to be a notable improvement in transparency and openness.
Weiss’s proprietary discrete electronics are utilized in both the line and headphone output stages. Constructed with a stainless steel chassis and a 10mm aluminum faceplate, the MK2 units are built for durability and aesthetic appeal. Each channel is equipped with a pair of 32-bit ESS Sabre DAC chips, providing excellent channel separation and noise rejection in both two and four-channel setups.
An internal high-precision clock generator operates at approximately 195kHz, enabling PCM signals up to 384 kHz and DSD x64/x128 to be re-clocked efficiently. The linear power supplies feature dual toroidal transformers and separate regulators for each channel, minimizing noise and crosstalk.
A key enhancement in the MK2 models is the analog stage, which now includes Weiss’s custom discrete operational amplifiers, the OP2-BP. These are individually designed and manufactured by Weiss to meet stringent performance criteria and surpass the performance of standard monolithic op-amp chips, contributing to a signal-to-noise ratio of 128dB.
The DAC501 MK2 and DAC502 MK2 share identical circuitry and components but differ in form factor. The DAC501 MK2 is a compact, half-width unit suitable for desktop, studio, and home systems, while the DAC502 MK2 features a full-width chassis and includes a four-pin balanced headphone connector on the rear panel.
User interaction is streamlined through a touch screen display, complemented by a full-function remote and a web interface. Both models are networkable and Roon Ready, facilitating integration into modern audio setups.
Pricing for the MK2 models is set at $11,995 for the DAC501 MK2 and $12,995 for the DAC502 MK2 in the United States, with Canadian prices at $15,495 and $16,795 respectively.
Upgrades from older DAC50x models are $2495 in the US and $3195 in Canada. The DAC501 MK2 and DAC502 MK2 are offered in black and silver finishes and are now available through Bluebird Music.
