Topping L70 Fully Balanced NFCA Headphone Amp - 4-Pin-XLR/4.4mm Balanced/6.35mm SE Headphone Jacks Amplifier 7500mW x 2 Ouput R2R Volume Control HiFi Amp Audio Hi-Res Preamplifier(Black)

Works great, clean sound, took a while to figure out without using manual pairing it with a E70 velvet sounds amazing, currently driving my Hifiman he1000 stealth. Would recommend remember the rule of diminishing returns. I feel like anybody busing that pair would be set for a long time.

Amazing amp! Reference-Grade Control, Effortless Power, and Dead-Silent Performance. Remote control, Volume know has a very satisfying click for each db change. The Topping L70 IMHO is a stellar piece of gear that punches far above its price class. Build quality is first-rate — solid chassis, precise controls, and a layout that feels engineered rather than just assembled. Sonically, it’s exceptional: a dead-silent noise floor, excellent channel balance, and abundant clean power that drives even high-impedance headphones with authority. It sounds magical with my Beyerdynamic DT 1770 Pro MKIIs. The presentation is transparent and dynamic, with superb imaging and detail retrieval that let the DAC’s character shine through uncolored. With balanced and single-ended inputs, multiple gain stages, and outstanding measured performance, the L70 is an end-game quality preamp/headphone amp. Highly recommended for anyone chasing true reference-grade sound without the boutique price tag. Next step The E70 Velvet!

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.

I thought this amp would have enough power for my Audeze LCD-S20. I was wrong. I then encountered a known flaw with Topping amps that affects planar headphones with low impedance and high sensitivity. The amp will go into safe mode and cut out audio when the volume is turned up beyond the 70 range. Topping tried to address this with a firmware update but this didn’t fix the problem. I returned the L70 and tried the A70 Pro and ran into the same problem. No issues with dynamic headp.

Both functionality and sound quality are extremely good.

Was an awesome headphone amp until it stopped working after two months - it was very difficult to find out how to get a replacement under warranty from Amazon support. The only thing I got is to send an email to the seller and to the service email of Topping. Meanwhile I have a headphone amp that does not work and is now a brick I paid $300 for. Will update this review once I see how service reacts. UPDATE: The Topping L70 turned out not to be a brick. The R5 error was an overheating error that rectified itself after I had let the unit sit for 24 hours unplugged. It now is working fine but I make sure to turn the unit off by the back power button instead of the front or remote on button. When working I give the L70 five stars - it really is great. What now gets to the one star is that the seller nor Topping themselves ever contacted me except for an email from Topping saying they received my email and would respond in a few days - its now a few weeks and no contact. So buyer beware there is no support for this product after the Amazon 30 day guarantee.

This is a fantastic and compact headphone amplifier, with circuitry to drive a Sennheiser HD800 with ease. It's compact as well; I use it on the road when a client needs to listen.

Works And Sounds Great! The relay clicking volume is not distracting at all! Functions and Feels like quality.

3回目の購入ですが、いつも迅速な対応で商品も、間違いありません。

After recently delving into the world of open back headphones, and picking up a portable DAC / headphone amp for my phone, I wanted to use my new cans listening to my hifi. However my hifi amp doesn’t actually have a headphone jack. So I had to listen through the headphone out of my old minidisc deck. So I decided to look into a dedicated headphone amp for my hifi. I didn’t need a Dac as I already have told trust Dac-R, so I was looong for purely a headphone amp, with balanced outputs, ideally with a remote, and no DAC. Oh and that sounded amazing. I settled on the Topping L70 as had all the features I need and also had some great reviews. So I bought blind! And I am so pleased I did. This amp sounds absolutely stunning with my Meze 109s. I have never described an amp as ‘smooth’ sounding, but this combo is amazing. Everything sounds just so damned brilliant, but without harshness, without too much of anything. This my description - Smooth. I listen to everything from DnB to guitar rock to classic piano etc. and so far everything g I have thrown at it sound fabulous, except…… Low quality Or poorly mastered tracks are notably poor. Feed this amp and headphone combo quality recordings and it will not disappoint. Oh and for anyone interested, i connect the headphone amp via analogue rca line puts from the ‘record out link’ RCA’s on my Rega Elicit R.

This is an excellent headphone amplifier, I recently upgraded to an A70 pro as some of my headphones can benefit from the extra power but I’m still keeping it because it’s portable, powerful, quiet and great sounding. Highly recommended.

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 headphones C2 as speakers and with Middle Button both are playing at the same time the 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
