The King is dead, long love the King ! Munich Highend 2018, Vitus Audio have officially launched a significant upgrade to the 8 year old multi award winning RI-100 Integrated amplifier. Logically named the RI-101, the new model sports the same main power supply and output stage but is upgraded in every other area.

An all new preamplifier stage powered by a complex and lower noise regulated power supply, the high resolution volume control from the Signature and Masterpiece linestages, the RI-101 provides even greater transparency, blackness and neutrality than before, taking it even closer to the openness and Class A purity of the SIA-025. On the technical and build side, the volume steps are also finer and the revised casing gives even better cooling.

The original and much loved RI-100 DAC module is still available for the RI-101 with a small price increase but a new supercharged network DAC+Streamer option is also available. This is a completely new design derived from the expensive standalone DAC’s in the Vitus catalogue and employs the flagship ESS chip with Vitus’s streamer which has full DoP support. Airplay, Roon, MQA, Tidal, Spotify are all be supported too via the Mconnect app.


The RI-100 is possibly Vitus’s most popular product. Ignore that it’s a one box integrated, this 300 Watt powerhouse will astound you with the sheer quality of its sound. The RI has purity, transparency and cleanliness that is normally the reserve of a Class A design. It has astonishing levels of grip and slam but is also capable of extreme delicacy. Rich, holographic and wonderfully textural and intimate, the RI-100 seems to tick every box that people are generally looking for in highend audio. Now available with an optional $6000 4-input DAC module, this single unit just needs a set of speakers to create beautiful music that was up until fairly recently.

“Even though the Reference Series represent our entry level products, they incorporate many specialist/custom parts. This has proven an expensive but necessary must in order to keep our highly regarded musical performance – an area in which we refuse to compromise. While the battery power supply is history, the overall goal of the Reference Series remains unchanged, setting a new standard for sound quality at the price point. A bold, but for us, a true statement.

Once you have heard the performance of this amplifier, we are convinced you will agree. The RI-100 is the first new product in the Reference Series. It is a fully integrated amplifier, which includes an optional phonostage and dac. In it’s full configuration, the RI-100 will act as a standalone control center, which takes both analog and digital sources of any kind. It also incorporates a full bypass function for use with external surround processors.

Although the RI-100 does not have our usual class A mode, it’s class AB setting is adjusted for maintaining the same musical performance as our class A amplifiers.”

The DAC Module

‘Vitus’s slot in DAC module for the multi-award winning RI-100 integated amp is finally here. Myself and UK importers Kog Audio are quite frankly astonished by the level of performance we are getting from this thing. The DAC module essentally turns the RI-100 into a fully fledged control centre, just add speakers for a truly incredible sound for this sort of pricepoint and a performance close to the fully fledged reference level RD-100 DAC.

The module costs just $6000 and slots into your RI-100 in a simple 15 minute install. It has four digital inputs – USB (dsd64), spdif & Aes (24/192), Toslink – and they are all selectable from the main menu or remote of the RI-100. The performance you get is quite something. Fire a melco or an Aurender into it as well and the overall result is genuinely what you’d expect from a VERY expensive system.
