A new power device provides the foundation for an upgraded output stage. This new transistor, first used in the Relentless Mono Amplifier, extends high frequency response, increases power handling by a factor of four and features tighter tolerance gain matching between complementary NPN/PNP pairs. A wider safe operating area and superior gain linearity provides greater thermal stability through...[more]

The Progression Preamplifier adds new features previously not included in a D’Agostino preamplifier. Most noticeably, the Progression Preamplifier features an optional digital module. The digital module adds coaxial, Toslink, and USB capability to the analog base model. A fully differential DAC handles PCM signals up to 24 bit/384 KHz and DSD signals up to 4xDSD (11.2 MHz). This digital m...[more]

Abundant power is required for realistic sound quality and is a cornerstone of Dan D’Agostino Master Audio Systems’ amplifier design. The Progression Stereo continues this practice. A graceful anodized Aluminum chassis houses a 2,000 VA power supply transformer coupled to nearly 100,000 microfarads of power supply storage capacitance. Paired to this foundation is a fully complementa...[more]

The pods themselves are CNC-turned and milled from hardened stainless-steel, oxygen-free copper, and hard black-anodized aircraft-grade aluminium. These materials create the constraining layers for the damping material that is alternatively clamped between to create a single traverse dissipating unit, which we call the QPod. Vibrational wave propogation through the floor, stands, and the equip...[more]

REFERENCE 110-Ohm AES/EBU Digital Link combats both noise and jitter and has hefty, precision construction to be able to transfer digital signals efficiently for reference-level musical impact. It has large, balanced solid-core OFHC center conductors and super quiet, precision-extruded Teflon dielectric with Advanced Expanded Foam Technology for superior 110-ohm impedance stability. Two OFHC br...[more]

REFERENCE Balanced Interconnect is designed for high-resolution source components and preamplifiers with fully balanced differential circuitry. It dramatically expands the realism of a sonic landscape while invoking a staggering level of detail and preservation of dynamic range. A fully balanced design from cabling through the precisely matched dual networks for each channel, REFERENCE is often...[more]

REFERENCE 75-Ohm Digital Link has a large, solid-core OFHC center conductor, super quiet, precision-extruded Teflon dielectric with Advanced Expanded Foam Technology for superior 75-ohm impedance stability. Robust custom designed gold-plated RCAs make 360-degree contact with the inner shield to combat noise and jitter. In addition, two OFHC braided shields separated by a Mylar coated foil shiel...[more]
