Where it sits
Sonic Compass does not score gear out of ten. Gear and listeners are plotted on the same seven axes, so a review tells you where a product sits — and you can see how far that is from where you sit. A position is a description, not a grade.

Warm and organic, richer in NOS and a little sharper in OS. High = warm on this scale.
Highly resolving, with fast clean micro-detail in plucks and strums and no etch or glare.
Deep, thick, punchy bass with organic weight and slam; the stack can go loud without strain.
Wide, full and three-dimensional with excellent layering; I could picture each instrument.
Fast, clean leading edges and transients on guitars and cymbals.
No sibilance, etch or digital glare; zero noise floor on the Steel Hearts; kind to poor recordings at volume.
Favours texture, emotion and realism over clinical technicalities; easy to sink into.

The LAiV Crescendo Verse is a US$849 desktop unit that puts a discrete R-2R ladder DAC, an active Class-A preamplifier and a headphone amplifier in one chassis. LAiV is a Singapore brand founded in 2023, and the name is pronounced "live". The unit was sent to me for review by Yee and Weng at LAiV. I used my Arylic LP20 as the transport and streamed Tidal from my phone, mostly with the HiFiMAN HE1000 UV, and I also tried it with the Arc Tec AB92 planars and the Palavox Steel Heart IEMs.
Listening journey
HiFiMAN HE1000 UV — A really good combination. I like detail, resolution and a huge stage, with natural, organic instruments, and this pairing gives all of that. There is a lot of treble detail and the leading edges of vocals are fast, but the whole sound stays warm, with great bass, and it is not boring. On AMH's Chasing Ghosts guitars are clean and full and the vocalist is beautifully balanced without being forward. The UVs can be a little V-shaped, but vocals did not sound recessed here.
Ozzy Osbourne, Crazy Train — The intro goes all around my head and well outside it. The vibraslap rattle is clean and crisp but not sibilant, Randy Rhoads' riff sounds real and lifelike, and I can pinpoint everything. The bass run is full and complements the rest of the song.
Bernth and Ichika Nito, Midnight Drive — Clean, resolving, powerful and exciting. Micro-detail in plucks, strums and slides is excellent, transients are fast and clean, the bass is deep, and each instrument is easy to picture in the space.
Pit Bailay, Vivaldi (New Club Remix) — Violins start natural and sparkling. When the track builds I turned it up too loud and the bass just exploded. The UVs are not bass cannons, but paired with a bass-exciting source the low end was euphoric, with detail and resolution as well. I would call EDM a must-listen genre on this unit.
Amon Amarth, Upphaf — Tight and deep, with a thick, hard-plucked acoustic guitar. The war drums sit in the background and Johan Hegg comes in rich, powerful and huge. The balance of resolution, opulent vocals and deep, punchy bass suits the UVs well.
Arc Tec AB92 and Palavox Steel Heart, The Aristocrats — On And Then There Were Just Us / Duck's End, the AB92s are not easy to drive (33 ohm, 90 dB/mW), yet the Verse's 1,100mW drove them with authority and ease. I raised the volume only two or three notches over the UVs and got loud, detailed, powerful bass with the same imaging and separation. The Steel Hearts on high gain had a black background with a zero noise floor at full volume, deep bass, and crisp, clean, well-separated instruments.
Critical observations
Where the Verse sits — Fluid, tonally rich, organic and spacious. It is the antidote to a sterile, clinical or sharp DAC that gives you a headache after 20 minutes. It favours texture, musical emotion and realism over clinical technicalities, and it still resolves a lot.
Bass — Deep, punchy and thick without bloat, with an organic weight and slam that some delta-sigma DACs do not give me.
Mids and vocals — Natural, lifelike and full-bodied, with the singer placed naturally in the middle of the room.
Treble — Highly resolving but warm and smooth. Hi-hats and strings stay crisp and fast, with no sibilance, etch or digital glare. On poorly recorded tracks you can turn it up and your ears do not bleed.
NOS and OS — NOS is the purest R-2R sound, richer, airier and more emotionally engaging. OS sharpens leading edges slightly and adds a touch more perceived speed and clarity. I preferred OS, though I was happy in either.
Against the Fiio K17 R2R — Two similar ideas, and the Verse is about US$140 cheaper. The K17 has far more power and streams. With both set to OS, listening to Greta Van Fleet's Palace For The People on the AB92s, the Verse had clearly deeper, fuller, weightier bass, a fraction more resolution up top and a larger stage, with a sense of grandeur that overshadowed the K17. It was obvious but not night and day, and it surprised me. The K17 R2R sounds great if you do not compare, and I still plan to use it for streaming.
Handling — The build is premium anodised aluminium with tempered glass. The 20x7 dot-matrix display has three brightness levels and can be turned off. The volume wheel doubles as the menu navigator, which took me a while to get used to, and the angled power button looks like it is biting into the display. The remote is good once you learn it, and I need it because the Verse sits on a different desk from the Eufonika H5KPCU it decodes for me. There is a micro SD card slot underneath for firmware updates.
Read this against your own profile — I want warmth and organic texture with real resolution, and the power to drive a hard planar. If that is you, the Verse fits. If you want a flat, analytical presentation, this is not it.
Honest limits — The unit was supplied by LAiV. By ear only, with no measurements of my own, mostly with one headphone and one transport. The K17 comparison ran from two different streaming sources after technical troubles, and the AB92s had only just arrived, so the pairing may have coloured the result. Specs and price are the maker's.
