I was particularly impressed with the DSD64 replay from the DS07, which sounded very much on par with that from the pure-native DSD playback of the S.M.S.L. VMV D2R DAC.

What we’ve got here is a very cool, very compact DAC and Preamplifier that is only about 5 inches tall, 3 inches wide, and 7 inches deep.

When I added the LNBH and SSZ to my system, I installed them together, so it’s impossible for me to separate their individual contributions. After a long run-in period, the changes became so compelling that I found myself staying up late, revisiting every song I’ve ever loved.
One of the most striking improvements was the disappearance of noise-related limitations. With these two in place, details that were previously buried in the mix became clearly audible. I could hear the subtle sounds of a vocalist taking a breath or even swallowing, which added an incredible sense of realism to the performance.
The overall imaging feels more precise, with every element in the soundstage locked in place. Music flows effortlessly, and the presentation is so engaging that it’s hard to step away from the listening chair. This pairing improved the technical side of my system while also bringing a level of musical connection that keeps me listening for hours.

I recently replaced the stock fuses in both my SSZ and Tempus PSU with the Graphene Sluggo.
Even at the start there was a sense that something had shifted, but this is not the kind of upgrade that shows everything in the first hour. In my case it really came into its own after about 300 hours. The first 50 hours the treble had a slightly tighter character and the mid-bass felt restrained. Around 150 hours the presentation started to relax, with better flow and more natural layering. By 300 hours dynamics felt settled, micro-details became more apparent, and the whole system sounded more connected.
What stood out most to me was the neutrality and transparency. It does not push the tonal balance in any direction, it simply lets the system speak for itself. Highs extend cleanly without harshness, keeping fine texture and air. The midrange has a natural presence with good retrieval of subtle detail. Bass is well controlled, evenly weighted, and separated with clarity.
On the SSZ, highs became smoother while keeping resolution, and the soundstage felt more open in both width and depth. Vocals gained more dimensionality compared to the stock fuse. On the Tempus PSU, tonal balance stayed consistent, but resolution improved across the range, making instrument separation easier to follow.
Mark at Vera-Fi has been great to talk to. Every question I asked was answered with detail and warmth, which made the whole experience more positive.
After this I plan to gradually replace all the fuses in my system with the Graphene Sluggo. For anyone using SSZ or Tempus PSU who wants more resolution and detail without altering the system character, this could be worth considering.

Purchased a pair of Vera-Fi Audio Vanguard Scout bookshelf speakers to replace my Fluance XL8S bookshelf speakers in the living room 2.1 system and am glad I did. In Stick Season by Noah Kahan Noah's voice has a low-level echo seemingly caused by the recording space, and it was hard to resolve in my Fluance XL8S based 2.1 system. Now, with the Vanguard Scout based 2.1 system, that low-level echo is better resolved at the same, low volume level (67dB or so on average at the listening position, C-weighted). There is that and there's the fact they're gorgeous looking speakers in the room. Very happy with this purchase.

This sub is a great value. I can’t think of any other sub in its price range that can compare.

I've had experiences with three different sluggo options, the high purity copper version, high purity copper with a gold immersion, and the graphene sluggo. The graphene sluggo was far and away my no. 1 choice; graphene is the best conductor of electricity that exists, and the graphene sluggo has been vapor-deposited with a microscopic layer of the compound. Graphene is actually just a single molecule of carbon, and though the microscopic layer deposited on the sluggo is infinitely thin, it still transmits current at a 70% higher rate than either of the two other options. The sluggo uses the proven concept of "skin effect," where the lion's share of the current travels across the surface of the sluggo. The graphene sluggo was absolutely superior to anything else I had access to, you can read my original review here:

The Naiu Ella Stereo Amplifier is the only amp in my collection of gear that has an amperage rating higher than 10 amps -- that wouldn't allow me use the more flexible Infinity Fuse unit that's user-programmable. The Swiss Digital Fuse Box arrived in a black case as opposed to the usual silver case, which was a really good look! Hookup was easy, and I robbed the Core Power Piggy Tail from my analog system to hook the Naiu Ella to the SDFB. After it burned in for 24-or-so hours, I took an extended listen, and the SDFB in the system with the Ella amp now showed the same level of effortlessness and clarity I noted in my original experiences with it in my all-analog system. And my principal assessment of the SDFB remains consistent -- the Naiu Ella in the digital source system now plays with more control and limitless dynamics -- it's almost like a completely different, more powerful amplifier. Very highly recommended -- once you hear your system with the SDFB, there's no going back!

A more cost-effective, user-programmable alternative to the Swiss Digital Fuse Box! And the dip switches allow the user to customize it for amperage and fuse type (slo-blow or fast acting) for compatibility with a variety of devices. You're not limited to a single device (as with the SDFB, which arrives pre-programmed for a specific fuse type and amperage rating), and that frees you to experiment with other equipment, easily helping you decide if you need additional Infinity Fuse units. The only thing necessary for you to do prior to placing your order is to confirm the fuse dimensions and choose the Sluggo (that replaces the fuse) or an upgraded version. And the Infinity Fuse will work with any device with a fuse rating up to 10 amps. Highly recommended -- I've tried it with tube amplifers, DACs, and preamplifiers, and the IF really gets you closer to the music!

There are a couple of qualities of these subwoofers that I would like to comment on favorably. First, the coverage of the midbass frequencies, and in fact the musicality of the subwoofers, is remarkable for the price. In my room, the frequencies between 65 and 125 are suppressed by the room. The Caldara subwoofers compensate for this very nicely. Second, the visual appearance of the units is very nice.
Wow, I miss the ultra low frequencies that my old but no longer functional REL subwoofers provided, my music room does not really allow for reproduction of the frequencies between 20 and 40 Hz. The trade-off of musicality is therefore significant compensation.
I appreciated Mark’s generous offer to substitute the Caldera for the smaller model which was out of stock. If I can make one suggestion for future Caldera models, it would be to have speaker level inputs in addition to the RCA inputs.

Wow - I honestly wasn't sure if I was even a "bass guy" before purchasing 2x Caldera 12"s, and my Wharfedale Linton's even had already solid bass response, but in the endless quest for the "wow" factor, I was pointed towards Vera-Fi's subwoofer offerings.
Let me just say, I am absolutely blown away. I can't stop listening to my system -- it just sounds too good. I also have not experienced such remarkably good customer service from a company in quite some time. Thank you to Mark and the team for making such a reasonably priced product that punches far into much higher price points.

The Line Noise BlackHole (LNBH) sets the new industry standard for AC line noise elimination. In both my systems, the LNBH in combination with the Snub Station Zero easily bested the AudioQuest Niagara equipment that occupied both systems. If you can manage with a combined amperage total of less than 10 amps (that's much easier than most might imagine), these devices will shock you with the goodness they bring to your listening sessions. Yes, they eliminate AC-borne line noise, but the opens an entirely new listening experience, with incredible transparency and clarity, whether you listen to analog or digital sources. Very highly recommended, and maybe the most important product launch from Vera-Fi Audio yet!
