Bricasti M20 dual mono preamp rarely listed for sale in pristine condition an end-game solid state preamp honest to the source with exceptional transparency, detail and excellent tone. All original packaging, shipping box and remote control. No fee with PP F&F.From the Bricasti web site:Reference tone:The attenuator is a discreet ladder of digitally controlled resistors in 1dB steps utilizing Vishay foil resistors in key locations in the circuit; we find them to have a unique sound so we employed them to impart a tonal character to the M20, and PCB material is made from ceramic materials with excellent dialectic properties. The final output buffers are a proprietary discreet design and level control is accomplished using a R2R ladder technique allowing for perfect balance and tonal character at any level with recall, programmable input offset and remote control capabilities.The M20 is a fully differential dual mono preamp powered by three linear power supplies, one for each of the analog sections and a separate supply for the digital control circuit processor to ensure isolation from the analog PCB and power supplies. So in this way the M20 is a full Class A design. The M20 comes complete with Stillpoints isolator feet.The M20 includes 2 balanced XLR inputs/outputs and 1 unbalanced, RCA input/output. Pre-set channel naming conventions from the display can be uniquely customized through the menu as well as fine adjustment of level offset. The trigger-out mini-jack on the rear can be connected to the our power amps like the M28s or DACs like the M21 to send a 5V DC voltage trigger to power them in and out of standby from power off or standby on the M20
The M20 is a notably serious, all-analogue preamp, and US$6,500 is a genuine bargain against the supplied market data: it sits below the US$6,182 25th percentile only marginally, but far under the US$11,035 median and well below the US$19,631 75th percentile. For a properly functioning example, that is compelling value rather than merely a fair price.
Its appeal is the fully differential dual-mono design, exceptionally quiet performance, precise 1 dB R2R-ladder volume control, and useful balanced connectivity. It is particularly attractive in a balanced system, with separately buffered outputs and a transparent, highly linear presentation. Since the listing gives little condition detail, confirm the remote, power cable, display, input switching, and both XLR/RCA paths before buying; with those present and working, this looks like an excellent opportunity.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Bricasti Design emerged in 2004 from Shirley, Massachusetts, blending New England precision with an Italian-inspired name derived from founders Brian Zolner and Casey Dowdell. Both veterans of Lexicon and Madrigal Labs—where Dowdell honed digital expertise and Zolner led engineering—the duo launched the company initially as a pro-audio specialist, crafting revered digital reverbs in a historic brick mill. Over two decades, this heritage has shaped a brand synonymous with meticulous, hand-built electronics that bridge studio rigor and home listening.
The lineup centers on high-caliber digital and analog components, with the flagship M1 DAC series establishing its reputation for transparency and musicality. Offerings span DACs like the M3 and M21, SACD transports such as the M19, monoblock amplifiers including the M28, and integrated solutions, all prioritizing proprietary conversion, low-noise power supplies, and versatile interfaces for PCM and DSD. Absent are speakers, turntables, headphones, or cables—Bricasti hones a focused arsenal for discerning digital playback and amplification.
Positioned firmly in the high-end boutique realm, Bricasti commands respect among audiophiles and professionals for its no-compromise engineering and restrained aesthetics. Priced from $12,000 for top DACs, it appeals to buyers seeking studio-grade purity in consumer hi-fi, earning consistent acclaim in elite circles without chasing mass-market volume.
