Ultra-High Performance NFCA Module
Adopts the same NFCA module with A90, it provides a high performance to driving kinds of headphones.
-
Low distortion while outputting high power
The L70 can maintain ultra-low distortion output under high power load.
-
Multiple Input Ports
L70 provides Combo and RCA input port, and is available for XLR, TRS and RCA connection.
-
Customize Settings
A safe volume can be set for the L70 to avoid sudden loud sound after power on/input switch
-
A Headphone Amp, also a Preamp
In preamp mode, you can get the 20ohm SE and 40ohm BAL output impedance to meet various power amp.
GND Ground Loop Noise Terminator
Ground loop noise may be encountered when multiple devices are used in combination. L70 has a GND/LIFT switch to solve this problem. When in normal use, set it to GND; and when ground loop noise is encountered, switch it to LIFT. Then the ground loop noise is terminated.
12V Trigger Interface
The L70 is equipped with a 12V Trigger in & out interface. With only one easy-to-obtain 3.5mm to 3.5mm cable, the L70 can be turned on and off synchronously with other devices equipped with a 12V Trigger interface.
L70 can easily drive different headphones.
-
Various Headphone port
L70 is compatible with common headphone jacks including: 4-pin XLR balanced, 4.4mm balanced, 6.35mm single-ended, and 3.5mm single-ended.
-
8 Output Settings
L70 can be adapted more personalized when connecting different earphones and other devices, wich greatly improves the convenience of use.

I have half a dozen DACs at any given time, but this is my permanent keeper. Amir at Audiosciencereview did measurements and it's flawless. I use an optical USB cable into it with an adapter and performance did improve slightly. The 9028Pro is a proven design and it fits on most of my amplifiers easily (if it's a hot one like the SMSL H300 I put it on a slotted 15" monitor riser for cooling). I'm using it tonight to compare the Topping A70Pro and the Singxer SA-1V2 that came in this week. I like the crisp display, and the new firmware added DPLL settings for adjusting optical connections for best performance. This is a huge help if you're connecting a TV or other device like that. This is one of those things they're not going to improve on since it's hit the limit of human hearing, perfect is perfect. My daily driver is the Topping A70Pro and E70 9028Pro and I buy $7k a month of audio equipment and have my choice of anything on the market. I did tests with the E70 Velvet and D70Pro Octo and Sabre in the same room over days with volume matching, and there's no way you'll hear the difference between them. Grab one and never upgrade your DAC again. Pair it with an A70Pro and you're never going to hear anything better.

Using Motu m2 as a DAC connected to L70 with Balanced cables (TRS-XLR)I've been using my Edition XS for a couple months with the motu M2 but when I was trying to go Loud the sound would start distorting because the motu couldn't provide enough CLEAN power.Sufficient to say that with the topping L70 I have gone to unbearable listening levels while testing and i have not heard a single hint of noise or distortion either through my speakers (edifier 1700bt -> RCA) or my headphones (Edition XS -> 4.4)While my goal was to just solve the distortion issue on high volumes and didn't expect any difference in sound quality, I was pleasantly surprised to find out that the sound got both a little bit warmer and the whole presentation I could best describe as seamless. Before I could occasionally find some harshness, which is not there anymore.I'm using LOW GAIN for all my devices, as the power is more than enough edition xs is set at -23 DB, but I've been A-B ing low and high gain setting to test, and there is no audible sound quality difference. The power delivery is just crazy strong.C1 profile I saved as my headphonesC2 as speakersand with Middle Button both are playing at the same timethe transition is instant and there is no delay between switching inputs. Oh and it also remembers the Volume/Gain setting for each input.I got it at 290 and if it stands the test of time I would say it's worth every euro but only time can tell. Highly recommended

This is a fantastic amp. I originally had issues with an Smsl c200 I purchased producing clicks/pops on my MacBook (this is apparently an issue with some Smsl products and other dacs with xmos chips through usb). So instead I got this and just used my MacBook’s internal dac, with a 3.5mm to rca cable. The sound is clean and there is a lot of headroom for eq. I don’t have any headphones that are difficult to drive but I have many iems, and sensitive headphones that still sound clear in low gain mode. I had a lot of noise running 3.5mm to xlr from my windows pc, so I ended up using an ikko itx-01 I had laying around. This unfortunately introduced a ground loop, but the ground loop switch eliminated nearly all noise. This feature alone makes the L70 a notch above its competitors. There is also a 12v trigger, which I have yet to use, but a very cool feature to automatically power the device on. I don’t really need the E70, but I like the convenience and aesthetics of having matching Dac amps. But for now, running from both my MacBook’s 3.5mm and an external dongle on my PC, this amp is amazing. I will stick with topping for dac/amps from this point forward.

I have a background in electrical and audio engineering, and previously used the Topping DX7 Pro for a few years which I used to drive a 2.1 active speakers+subwoofer setup, as well as headphones and IEMs (its biggest flaw, albeit small is the high output impedance on the headphone amp which can affect the frequency response of low impedance headphones). I had intentionally picked the DX7 at the time because it was an all-in-one integrated DAC+amp, but more recently, I purchased a MiniDSP Flex to use as a DAC with the benefit of getting Dirac room correction (which gives a better resulting sound than I can ever get playing around with just PEQs in REW and Peace in Windows). So now I was in the market for a headphone amp and speaker pre-amp. Enter the Topping L70.The Topping L70 lets me keep the single-ended 6.35mm, and differential/balanced 4.4mm and XLR headphone plugs that the DX7 had, while acting as a pre-amp to my active speaker setup connected over XLR (the subwoofer is directly connected to the Flex, only the bookshelf speakers get passed through the L70 as a pre-amp). With the newer features this offers (improved HPamp which provides more than enough power with >120dB SINAD on both the balanced and unbalanced plugs, volume memory, up to 21bits of dynamic range resolution to take advantage of 24bit audio), I would consider the L70 endgame material that can be paired up with any discrete DAC of your choosing, especially at its price point.

This is one of them finds where your left scratching your head wondering how have they done it for such a low cost I have amp from Burson that cost many times the amount and to be honest I find the topping everybit as good and as capable if not more I fully recomend this amp.Ufortuantly In the uk if we have to pay pretty much twice the cost of where these places buy these gadgets from china My advise is if you can find stock there do so and get this for much less but a brillant little quality made amp Indeed.
