## Overview

The Helot 2x Headphone Vacuum Tube Valve Amplifier combines UK and China craftsmanship to deliver a warm, smooth listening experience using premium Electro Harmonix 12AU7 and 12BH7 tubes. With a wide frequency response of 20Hz to 30kHz and support for headphones ranging from 32 to 600Ω, it’s designed for audiophiles seeking rich tone and relaxed, low-volume acoustic or vocal playback. While it excels in smoothness and detail at moderate volumes, it’s best suited for headphones with moderate impedance and may clip with high-demand models at higher volumes.

## Description

This amplifier has been designed and manufactured in the UK and China. We have worked with our factory in China to build a high quality headphone amplifier that doesn't just use the cheapest components we could find. Once it arrives in the UK it goes through the final stages of construction as well as a series of quality checks. Optimal setup. We recommend this setup for best results but the unit will work with a number of other combinations. Choose what works for you. Headphones plug directly into amp with 1/4 jack > 2 RCA cables > CD player Which tubes? Please note that the observations below may not apply to all setups. In our experience, with the JJ tubes it is much easier to distort the tracks heavily when playing with the volume on the amp/play device maxed out. It makes it quite fat and bassy. This is only when everything is maxed out and rolls off slightly. If you want the option for more distortion, these tubes might be the best choice. EHX sound a bit smoother and warmer. These are harder to get incredibly distorted. Even at max volume everything remains very usable. THD (Total Harmonic Distortion): 95 dB Headphone Impedance: 32-600 ?.

Review: Nice sounding amp for lower level listening on vocal/acoustic. The company is great to deal with. - Sources are LP5X with ML / Michael Fidler phono pre or WiiM mini bit perfect out to JDS Labs EL DAC ii+, both then to a Fosi P4 Pre. The amp is silky smooth, very little background noise, but not pitch black. It is smooth, relaxed & melodic, with reasonable detail. Female vocals are beautiful. Definitely worth the price paid. It takes a good while to warm up to its best, so turn it on an hour before you want it. I should also mention Spartan here too. I've had a couple of queries and they get back to you quickly. Customer service as it should be, but often isn't. This is an update after a year and a few headphones & amps later. Everything noted above stands, it is super smooth and easy on the ear, but I would add that this amp is at its best for lower level listening with acoustic / vocal music. If you want the greatest detail, high volumes and tight bass, look elsewhere. Bass distortion is clearly evident at high volumes, regardless of source.
Review: Clips, clips and clips - If you're looking for a tube amp to use with multiple headphones, look elsewhere. I have nothing but issues with the amp clipping at normal listening volumes on two pairs of headphones. My modded pair of Sennheiser HD600s work fine and don't have any clipping, but my modded HiFiMan closed back Sundaras that need more volume over the HD600s, just clip like crazy. They're totally non-useable with this amp. My AKG K612 Pro headphones also start clipping at normal listening levels, as these also require more volume over the HD600s. Spartan Music claiming this amp can drive 600 ohm headphones is incorrect. I also wouldn't bother with anything under 100 ohm either, as the amp has a high output impedance and so my Beyer DT900 Pro X and Grado SR225X headphones are non-useable unless you use an EQ. I've swapped the Electro Harmonix tubes for a Japanese Mazda 12BH7A and an RCA 12AU7A, but it did literally nothing to the clipping. It has good build quality and it does sound good with the HD600s, but it seems the amp design itself is poor, and you'd be better off looking at the Little Dot MKII which I also have and which doesn't have any issues with any of my headphones.

### ⭐⭐⭐⭐⭐ absolutely perfect valve headphone amp, sounds great
*by A***I on 17 May 2023*

I was after a good headphone amp with no frills to connect to the already excellent MSI Z790 ACE motherboard audio output which is really really good to begin with, but I just found listening to a tube amp just slightly better, cant really put my finger on it, but there it is. After some research I came upon the Helot amp and bought it, and so glad I did. It is excellent with my Sennheiser HD650 headphones and arguably as good as my Little Dot MkIVSE which I have downstairs which also has HD650 headphones. Now the only fly in the ointment which is most likely why people report that the unit runs hot. Your house mains voltage may be too high!, the filaments in the tubes are designed to run at 6.3v ac and they do if your supply is at 220v ac, but if like mine it is at 248 to 251v ac you will be driving the filaments at over 7v ac!, this will reduce the life of the tubes as well as generate a lot of excess heat. I built a buck transformer PSU to drop my supply from the 250v down to 220v ac so am using this and the amp is warm, but that is about it. It will still work at a slightly higher voltage but your tubes will burn out quicker and the unit will run warmer. I'm writing this listening to TIDAL streaming master quality tracks and everything is so detailed, and has a wide soundscape, no need for equalization, everything is just lush. I would really recommend this amp for the price if all you are after is a vacuum tube amplifier, no frills just an RCA input, On/OFF switch, volume knob and 1/4" headphone socket, paired with Sennheiser HD650's it's fantastic. Just to add the amp sits on the Topping E50 DAC perfectly, almost as if it were made for it, the amp is just a fraction narrower. The audio from these two combined is just brilliant with the HD650's, its absolutely brilliant and I have spent days and days listening to it. So pleased.
