The original Succinct was built on commission and again it was a 180W Class D amp. The owner lost all in our latest bushfires. By accident I found this out and offered to replace the amp for cost of parts only. We added a tube preamp to make this a true integrated.
It is all housed in a light weight 2U charcoal 19” rack mount. There are two inputs selected by a small front switch. The onboard PS with the hifimediy T4 module is used here and a Radi0kit 12V/250V PS is used to power the tube section. The tube is a Raytheon 12AU7 and the preamp is built on a small piece of Vera-brd. The tranni is 300VAC and connects direct to the amp module. The amp module has speaker crowbar protection. Twenty second delay on and immediate off.
The sound, as usual from these T4 modules, is pristine, very detailed and with excellent bass drive down to 30hZ the limit of my speakers. For way under $AU1K this amp has a stack of power (180W into 8ohms) and crystal clear with only a touch of tube warmth.
