What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 95/100
The review describes an unusually quiet, detailed and effortless presentation, combining strong control with a notably natural musical flow. Spatial reproduction is a particular strength, with exceptionally distinct placement and a deeply immersive sense of silence between instruments.
Transparency Resolution
96/100
Home Theater Review found the Progression’s noise floor audibly lower than its McIntosh reference and praised its quiet backgrounds, speed and detail. The reviewer says it delivered a level of detail beyond what they had heard in more than 20 years of reviewing high-end electronics.
Tonal Balance Musicality
94/100
The presentation was described as effortless and highly musical, with music flowing more naturally and rhythm and timing sounding more believable. The reviewer also characterizes its character as offering tube-like warmth without the operational drawbacks of tube equipment.
Dynamics
95/100
The Progression reproduced demanding material with no perceived compression or loss of dynamics. Fast, deep and tightly controlled synthesized bass was singled out, alongside an overall sense of ease and drive.
Soundstage Imaging
96/100
On Jennifer Warnes’ “Bird on a Wire,” the reviewer heard imaging better than ever before in their system. Instruments were distinctly placed, while the black space between them improved definition without artificial edge or etching.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
92/100
Home Theater Review calls the Progression’s fit and finish “in a class of its own,” an especially strong endorsement of its external execution. The review provides little further detail about internal construction or long-term durability, but the reported finish quality is clearly exceptional.
Features Connectivity
88/100
The analogue section is generously equipped with four balanced XLR input pairs, two RCA input pairs and two balanced XLR output pairs. An optional digital module adds USB, optical and coaxial inputs, extending the preamp beyond a strictly analogue control center.
Value for Money
85/100
At roughly $30,000 to $36,000, the Progression competes in an uncompromising luxury-preamp segment. The review is emphatic about its sonic performance, but does not directly compare its price or value against competing preamplifiers.

Manufacturer's Description — Dan D’Agostino
Versatility, Performance, and Value
Designed to deliver the greatest value in genuine high-end audio, the Progression Preamplifier delivers versatility and performance. An optional, field-upgradeable Digital Streaming Module adds coaxial, Toslink, and USB inputs 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 module feeds a discrete, fully complementary and balanced analog signal path from input to output. Negative feedback is not used anywhere in the Progression Preamplifier, nor is it necessary. Open-loop distortion is less than 0.006% and the open-loop bandwidth extends to over 100 kHz.
Advanced Control
The volume control is realized with a stepped balanced resistor ladder, using high-linearity solid-state relays and discrete precision resistors. The bandwidth and transient response of the preamplifier circuitry are unaffected by volume setting. The Progression Preamplifier has two independent outputs that can be individually operated or used simultaneously for driving a second amplifier in a subwoofer-based system. Bluetooth extends the range of the remote control by a factor of five and eliminates line-of-sight limitations that are inherent in IR remote controls.
Separate for the Greatest Isolation
Housed in a separate chassis, the power supply of the Progression Preamplifier makes use of extensive electrical and magnetic shielding to keep radiated interference away from critical preamplifier circuits. Internal circuitry filters RF noise on the AC power line and compensates for asymmetric power waveforms and DC on the mains. A second DC output is included to power future Progression source components. Two analog meters, inspired by Swiss watch faces, function as signal meters during music playback. When volume is adjusted, the meter needles change to volume setting indicators. After adjustments are made, the meters revert back to signal meter operation. The meters also function as balance indicators when adjusting balance.
