The analog platform provides two pairs of SE inputs and four pairs of XLR inputs. XLR preamp outputs allow for easy addition of subwoofer(s) into a system.  The Bluetooth remote eliminates line of sight issues and extends the usable range.

The optional digital module was added as originally built, including one SPDIF coax, one Optical, one USB-B and one RJ-45 inputs.  Compatible with Roon, Tidal, Qobuz, and MQA digital technologies.  The fully differential DAC handles PCM signals up to 24 bit/192 KHz and DSD signals up to 4xDSD (11.2 MHz).

The optional phono stage was also added as originally built with 60db gain, with a wide variety of loading options.

Two analog meters function as signal level 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 level operation. The meters also function as balance, phase, and mute indicators.

The Progression Integrated outputs 200W @8 Ohms and 400W @ 4 Ohms. A unique toroidal winding technology delivers greater power output from a similarly sized conventional transformers, meaning the Progression Integrated is small for its capability. Internal circuitry filters RF noise from the AC powerline and compensates for asymmetric power waveforms and DC on the mains.
