The Veros One uses a different minimalist AZF circuit from the Phono 2-SB for superior low-level resolution for both Moving-Magnet and also Moving-Coil Cartridges.

The Veros One, LKV Research’s top-of-the-line phono preamp, provides the ultimate in musically accurate LP reproduction. Designed by Bill Hutchins, creator of LKV’s highly acclaimed Phono 2-SB, the Veros One takes the excellent performance of the 2-SB to a higher level with precision parts; innovative RIAA circuitry; accurate, extremely quiet gain blocks; revised power supply regulation and filtering; and an output buffer that delivers astonishingly good performance even into low impedances.
Moreover, the Veros offers the user convenient, panel mounted switches to select among 10 cartridge loading options and two equalization curves: the precisely accurate “RIAA” network, and the warmer sounding “Contour” network. Like the Phono 2-SB, the Veros one accepts balanced and single ended inputs and delivers its output in either mode.
The result is a phono stage that removes the remaining veils between the listener and the music. The soundstage is deep and the images within it precise and solid. The music arises out of a still, black background revealing all the low level information that is critical to the meaning and emotional impact of the music. Dynamics are startling. The sound is detailed but natural and harmonically true.
Dynamic Headroom accommodates the wide dynamic swings of music with neither strain nor compression.
Flexibility to function properly in a very wide variety of systems, accommodating almost all cartridges, especially low-output, moving-coil models.
External Power Supply and Dual-Mono Topology minimize both noise and crosstalk.

AZF Circuit. Fully differential, class A, zero feedback gain blocks implemented with low-noise JFETs without need for step-up transformers.
_________
External power supply with custom designed toroidal power transformer and low-noise HEXFRED rectifier diodes delivers seven stages of power regulation and filtering with soft start protection.
_________
Two user-selectable equalization networks:
- An RIAA network and a contour network that allows the selection of a slightly warmer sound.
- Accuracy of ± 0.1 dB achieved with 0.1% metal film resistors & 1% tolerance polypropylene capacitors.
_________
Cascode gain circuitry, stiff current source biasing and hand matched JFETs (Idss less than ± 0.1 mA) minimize distortion.
High current JFET output buffer drive long cables and low impedances.
Extensive on-board voltage regulation and filtering assure clean, stable power supply rails for the gain circuitry.
Soft start protection reduces component failure.
Differential (balanced) amplifier circuits block noise.
Dual mono construction with separate circuit boards decrease crosstalk and enhance imaging.
Four-layer circuit boards shorten the signal path length and connect grounds to the same plane lowering noise.
Balanced input with selectable Balanced or Single-Ended output.
Single-Ended input with either Balanced or Single-Ended output.
Balanced (XLR) Output: 40, 48, 58, 62, 65, or 70 dB Selectable Gain
