TOPPINGL30II NFCA Linear Headphone Amp - 6.35mm Jack 3.5mm Adaptor RCA Input and Output 37Vpp high Output Voltage Mini HiFi Amp Audio Hi-Res Preamplifier (Black)

I enjoy listening through headphones quite often, and I listen through some fairly expensive gear. One being a MCIntosh MHA 100 headphone amp and another amp, a Primaluna Evo 400. This was purchased to obtain a decent portable setup for my office which changes. I run this with a very inexpensive Aiyima and Topping Dac. And I must say my over all impression is that I am very happy with with how well this headphone amp performs. It’s DEAD quiet and sounds neutral it’s presentation. I use it with a preamp in between this and a topping DAC. The preamp allows me to have tone controls, as I like to have some flexibility. Let me tell you, for the price I don’t think you can beat it. I has enough power to drive many headphones and delivers more than enough I need with three gain settings (low, med, high) with a smooth volume knob. This entire setup is just around 300 dollars with the most expensive piece being the headphone amp at half that. So not bad at all. I think most people who try this amp will be very pleased. I havnt tried to bypass it to see if it’s completely or neutral or now with it running between a source and say, and amp that doesn’t have a headphone out. For those with amps that don’t have a headamp out, this may be a be try good solution, or for those that want a cool little desktop setup. Overall a win A+.

Pros:+ Super, super low noise. Even at high gain and max volume, I am not hearing any noise.+ Love the physical toggle switches for selecting gain, and device function (Pre-Amp/Headphone Amp/Off)+ Powerful enough to drive my HIFIMAN SundaraCons (these are just nitpicks, really):- Large power adapter, but I understand that it's a trade off. With external DC power supply, the amp doesn't need to use an internal switching power supply, which improves its noise performance, but it is still an incovenience- In a darkened room, it can be hard to see the position of volume control knob. Which the indicate (which is really small) was more noticeableOverall, an amazing performance for such a small, affordable device. Very happy with it.

Audio quality is very much unmeasurable. "This sounds better than that" says everything and nothing. All I know after a few weeks of using this amp is: I no longer enjoy the headphone outs on my UAD Apollo x4 audio interface. Even when watching movies or gaming, there seems to be an airy quality in the Topping sound that I could not put into numbers or descriptive language. That said, I can think of a lot of things that would make this little box more enjoyable to use: The front panel is horrible. Who likes glossy plastic these days? The positions on the 3 position on/off switch are unclear and need to be memorized rather than read (There is some white 4pt. type on there somewhere.) Optical TOS input would be MUCH appreciated. These are all gripes that don't matter a whole lot. The little thing delivers more volume than you'll ever need, even with finicky 250Ohm headphones. And it renders the audio with clarity and authority. Plus: I appreciate the price!

Exactly what I needed for a dedicated headphone amp. Small and compact. Delivers crystal clear sound

This amplifier is paired with a Topping D-10The three-setting variable gain is a big plus. My planar headphones like lots of current. Many headphone amps don't have enough power to adequately power planar headphones.In the high gain setting this amplifier has more than adequate power. At roughly half volume it is more than loud enough with my HiFi Man HE-4XX.

Excellent value. First major improvement go my audio quality since my initial headphone purchase when paired with my Topping E30. Absolutely worth the money long-term, although I may not use these as a primary beyond next 2-3 years. We shall see.

Great sound, plenty of power for most headsets, even HIMAN edition se.

This thing has incredible measurements for the price. It sounds glorious and I would highly recommend for a great mid-fi headphone rig. I have a LG V60 fed into Sennheiser HD6XX and I can get lost for hours. Not fatiguing at all.
