Vitus Audio’s RI-101 MK2 integrated amplifier is a showstopper, with technical prowess skillfully woven into the product in the absence of sporadic design decisions. Beyond the symbolic meaning, and the reproducing of the authentic spirit of the music, the RI-101 MK2  permeates the market in a completely different way.

And this is put into practice at once with listening. So many amplifiers come with a fast and slow charm that fades with time. With the Vitus Audio RI-101 MK2, the honeymoon period simply doesn’t stop and it brings a seismic shift when it comes to the realms of integrated amplifiers, with both clarity and natural warmth that leaves many peers behind.

The Vitus Audio RI-101 MK2 is not only a fully-fledged state-of-the-art integrated amplifier but also a quiet, everyday partner destined to serve audiophiles, high-end audio aficionados, and music lovers. It follows the philosophy: when there is nothing more to add, but also nothing more to take away the circuits are endowed with pure Danish, Nordic minimalism with zen-like balance and a vibrancy that is bursting with contrasts. 

When it comes to the upper echelon high-end audio reproduction, either the music sounds right or it’s a sonic red herring.

Art Audio’s Opus 4 monoblocks managed to convey an impression to me of nearly as much depth of overall musicality as the 275 Watts of ultra-linear power of my other reference system amp, the CJ Premier 8A. I ultimately decided to keep the Carissa amplifier as part of my system to use with the Quad 57s and as an alternative for the 63s when they are not connected to the big CJ amps. The power, control, and sound along with the lavish and lovely looks of this latest revised Art Audio 18 Watt SET amp as designed by Tom Willis is highly recommended to be seen and heard.

Art Audio’s Carissa vacuum tube stereo amplifier has character, a distinctive beauty, and elegance that it continues to be part of my reference system. If you are looking for an elegant-looking design and musically refined, and lovely sounding amp in a more powerful rating range, then seek out an audition of the Art Audio Opus 4 monoblocks that have a diminutive look and weight yet produce a prodigious, powerful, and excellent quality output. Bravo to both Tom and Scott for their excellence in design, musical listening, and customer support throughout this evaluation period.

At the conclusion of the review, I had another concern. As much as in enjoyed my time with this amazing integrated amplifier, as much as I want to give it a 10 out of 10, the Konzertmeister and Kapellmeister out yonder on the horizon constantly remind me that it can get even better. That’s always the case with high-end audio reviewing, that it’s foolish to call something the best since you’ll probably find something else you like better in a couple of years. For example, you might conclude that the Meishu has distilled my love and admiration for the Allnic Audio T-1500 Mk. II integrated I’ve been yammering about for the last couple of years. The answer there is simple this: the Allnic costs less than half as much as the Tonmeister, and that’s an important consideration. By the same token, the Konzertmeister and the Kapellmeister, from my limited exposure at this point in time, surpass the performance of the Tonmeister but at a substantial cost. I’m sure there’s some 300B amplifier out there that retails for some ungodly amount and destroys all other amps in its path, but that’s just audiophilia nervosa rearing its ugly little head. If you can’t be with the one you love, in other words.

The rapid-fire, start-stop crack of Neil Peart’s drums contrasted wonderfully with the saturated sound of Lifeson’s effect-laden guitar. This isn’t subtle music—it’s life-affirming rock that’s jam-packed with information, and the Brama sorted out the details while retaining all of the power. The Brama’s midrange is admirably clean and neutral, yet at the same time it remains extremely expressive. The quick bursts of crackling distortion backing up Geddy Lee’s voice in the chorus stood out as discrete elements, and Lee’s voice cut through clearly, unmuddied, without artifice.

Up a little further, into the lower treble, the Brama injected a small amount of texture into Peart’s cymbals and Lifeson’s incendiary guitar solo. As I listened to “Freewill”—and, heck, pretty much every other piece of music via the Brama—I nodded my head in admiration at the way this amp treats the overtones that are the hallmark of listening for pleasure rather than analysis. I could probably rephrase this to claim that the solid-state amps and preamps I’ve been using over the past decade have failed to reproduce some of the inner light and harmonic realism that’s integral to live music, but I think that’s just a tiny bit of a stretch. Still, there’s definitely tube magic flowing from the Brama’s 300Bs.

I just loved that sound, that tiny ember, that warm glow. It seemed to fill in some of the gaps in the 805s’ wildly spacious sound, making them sound more cohesive and realistic. It was never overdone, remaining exceptionally subtle. Though I could really only identify it in certain isolated instances, I can’t help but think that the tube richness was at least partially responsible for the image solidity I’ve already raved about.

Next up were the Russian Mullard CV4004 stock tubes. This was better. Less detail, sure, but a more fully rounded sound and no hole. I could live with these tubes. They did nothing wrong, but also did not do anything outstandingly well. Just solid-sounding tubes. Maybe it was not terribly surprising, but these sounded similar to the Mullard 12AX7 tubes from Great Britain, and it was six of one and half dozen of the other – between the two. Best to go with what is available and less expensive.

The next tubes just smoked me, the Amperex Bugle Boy tubes. I was not prepared for this degree of difference. Unlike the Mullards, which did everything very nicely, these tubes did everything exceptionally well. Darn, the guitars sounded like musical instruments instead of a copy of a guitar. What a fantastic sound stage, wide and deep, and “Yeah, I am a sound stage freak,” and these delivered. Powerful low end, both the low bass and the mid bass. Very lifelike male and female voices. These tubes simply had no weaknesses. Sign me up for these. Now I wonder what they would sound like in my McIntosh C2200? I do not want to know because they are not inexpensive tubes, and I’d need four of them.
