Vitus Audio at High End 2017

Reading Time: 3 mins read

Hans Ole Vitus, founder and owner of Vitus Audio, states:

Ok, so we are here at the High End show 2017 in Munich. We are in Atrium 2 room 208, the Vitus Audio room, in corporation with Göbel and Purist Audio Design. We are presenting our new Vitus Audio Signature Series SM-103s, a world premiere. They are the last revision of the old SM-100 that we brought out in 2005. So this particular product has been on the market now for 12 years. One of the main differences here is on the power supply. A lot of work was done on the power supply. I can go into a lot of details with that, but please contact me and I’ll give you all the details you’ll need. Another thing that we also did in these mono amplifiers, like we did in the stereo amp that we presented here last year in Munich 2016, is that we took the sound modes from our Masterpiece Series products and put it into the Signature Series products. This is the last product where we actually introduced the sound mode. The sound mode, just briefly, is really a two different configuration of the output stage, which gives different sounds. We have are classical mode, which is what we are know for; a typical class A sound. The rock mode, in lack of better, is a little more forward sounding, a little more edgy. People might call it more dynamic, which is not the case, but it’s a good way to describe it.

Yeah, so this year we chose a different speaker then we’ve used the previous years. We wanted to have a speaker which would be capable of bringing out the new technology in the Vitus Audio Signature Series SM-103s, on a different level that we’ve been used to. For that reason we chose for Goebel speakers, they are a local company here in Munich. Their bending wave driver is very interesting. I don’t know much of its the technical details, but there are a lot of patents involved. The most interesting thing for me is how it works. One of the key things is that it’s almost like a full range driver; it goes from 170Hz to 30.000Hz. It’s as full range as you’d probably can get them. The Goebel speakers contain the resolution of an electrostatic speaker or panel speakers, but they have a different way of creating energy. The dynamics are better then I’ve heard before. Ad that with their special woofers, you get a very neutral, high bandwidth and interesting speaker. They have the capability of revealing all the details that our amplifiers can produce. So, we’re very happy with this corporation.

  • Two sound modes borrowed from the flagship line

A twelve-year-old design, revised for a world premiere

The Signature Series SM-103 monoblocks are, by Vitus Audio founder Hans Ole Vitus’s own account, the latest revision of the SM-100 the company first brought to market in 2005 — meaning the underlying design has been on the market for roughly twelve years by the time of this 2017 revision. Most of the engineering attention this time went into the power supply, a component Vitus singles out as carrying the bulk of the changes over earlier revisions.

Two sound modes borrowed from the flagship line

Following the stereo amplifier Vitus Audio introduced in Munich the year before, the SM-103 monoblocks carry over “sound modes” first developed for the Masterpiece Series: two configurations of the output stage that change the amplifier’s character. The classical mode aims for the brand’s familiar, typical Class A sound, while the rock mode is described as a little more forward and edgy — not necessarily more dynamic, but voiced to read that way.

Frequently asked questions

What is the Vitus Audio Signature Series SM-103?

The SM-103 is a monoblock power amplifier and, according to Vitus Audio founder Hans Ole Vitus, the latest revision of the SM-100 the company introduced in 2005.

What are the SM-103’s two sound modes?

A classical mode voiced for a typical Class A sound, and a rock mode described as more forward and edgy — a feature carried over from Vitus Audio’s Masterpiece Series.

What changed most in this revision of the SM-100 design?

Hans Ole Vitus points to the power supply as receiving the bulk of the engineering work in this revision.

Publisher

Marco Lisi is the publisher of Best of High End, part of AV Concepts BV. His path into audio started early: as a teenager he was drawn into the world of free radio, presenting shows and living immersed in music every day. In his early twenties he ran his own production studio for five years, creating jingles and commercials — hands-on training in sound design, pro-audio workflows, and critical listening through studio monitors that still shapes how he evaluates gear today. He also spent years DJing in clubs before moving into publishing, first at two earlier online magazines before founding Best of High End. His hi-fi and home cinema passion was inherited from his father, an inveterate system-swapper. Marco's first setup — a confirmation gift — paired AKAI separates with entry-level Bowers & Wilkins speakers, a brand he stayed loyal to for years as his system grew from stereo into full surround and home cinema. Like many enthusiasts, he went through an extended "audiophile" phase chasing the next upgrade, before settling into a more grounded view: gear as a means to enjoy music and film, not an end in itself. Years of critical listening have given him a well-trained ear — the ability to characterize a system or pinpoint a change in the chain quickly and accurately. Just as important, his teaching background (a Belgian "regent" degree in Dutch language) gives him the tools to translate those listening impressions into clear, readable writing.
