The Pegasus is a standalone desktop pure DAC with fixed voltage single-ended and balanced analog outputs and an array of modern digital inputs. Some, like Burson Audio, go a little further by diverting some delta-sigma duties such as I/V to discrete opamps which is more of a hybrid solution.
Parameters for delta-sigma adjustment are usually limited until you get to the analog side where opamps, rollable or otherwise, can take up the slack and introduce whatever flavor you like to the sound. Delta-Sigma is traditionally an all-in-one solution, a jack-in-the-box design to take a lot of the legwork from a company’s R’n’D budgets and reduce costs. Beyond the initial FPGA DSP and oscillation controllers, the core functionality is more or less the same.īoth delta-sigma options deliver excellent but different listening experiences but from an engineering angle, going discrete with R2R means you are 100% in control of the implementation. I say partially because some of the Burson DAC chipset functionality such as I/V has been pushed to their rollable opamps for greater control on the sound signature. Examples of which include Topping’s D90 or partially Burson’s Composer 3X Performance with their mix of Sabre or AKM chipsets.
Now for those new to R2R, this is an entirely different approach to your traditional delta-sigma single DAC chipset implementation. There are cheaper at around $799 with the Denafrips Ares II which sadly, we do not have here to compare, but there are vastly more expensive such as the hugely praised Holo Audio DAC range that can climb to $5000. The Pegasus R2R DAC is their debut audio product and in fact, their only product to date and competitively priced at $1099 for a modern R2R DAC. Musician Audio hail from China which seems a mecca for R2R creations these days and are very new to the scene as a company but claim to have some significant engineering pedigree in their team to back up their products. The Musician Audio Pegasus is our second R2R DAC but this time it’s the full desktop experience with all the associated bell and whistles for full system integration. But it does have a line-out and it can work with a desktop amplifier as an R2R DAC with a 4.9Vrms/3.1Vrms switchable design.
The P6 uses a pure R2R DAC topology, albeit in a portable format so without a lot of the extensive connectivity you associate with desktop options. We recently reviewed the high-end Luxury & Precision P6 DAP, (and the Pro version). This is not my first R2R experience, doubtless, it will be our last as some of our team are working on bringing some other DAC’s to the review table.
