I wasn't really a believer in digital amplifiers, and have always appreciated the classic AB design for its warmth and musicality. No digital processing - only direct bypass, from music source-to-amplifier-to-you. After seeing a lot of buzz around class T amplifier, I had to see what it was all about, and got myself the Lepai to check it out. I was thoroughly surprised, not only at how much sound was coming out of a modestly priced and sized unit, but also a tone that wasn't surprisingly.. digital, but rather transparent and clean. One downer - the Lepai was cheap. It felt cheap, and after a certain volume, it sounded cheap and distorted. And there was a pop when I turned off the LePai. But I knew there was a lot of potential in class T amps, researched and debated between Dayton Audio and Topping.
I am SO GLAD I bought the Topping. The build is solid, classic and simple. If you're a music purist, you'd know that you don't need much more than a power button and volume control. And it's everything I liked about the Lepai + quality + better sound. No pop, no hiss, not even a little bit and runs cool. I tested it with several bookshelf speakers - Infinity, KEF, Boston, and currently have them paired with Definitive. Love it. Very clean sound. And more than enough volume for a 20x10 room.
Please note this is not the amp if you're trying to throw parties. And for the not so great reviews, I wonder if they realized that speaker pairing matters, as well as the audio source.Read more ›
I was at first quite skeptical of the way Topping rates the power of this amp - 13W into 8 ohms at 10% THD. The other amps and receivers I considered were more conservatively rated at between 0.1 and 1.0% THD. (I found a specification of 6W into 8 ohms at 0.1% THD for the Topping at various websites, but Topping doesn't include this datum in the manual packaged with the amp. The manual does however give more detailed info for 4 ohm impedance loads.)
Before I give my appraisal, let me describe my particular setup. My listening room is 10' X 15'. My music source is a computer, to which I've ripped my Audio CDs (mustly classical music) into flac format. Between the computer and the amp I have a USB DAC. The amp powers a pair of Polk Audio Monitor 45Bs. I also have a Polk PSW10 powered subwoofer, fed by the DAC. Nothing exotic or expensive, but the amp is the least expensive component. My interconnects are of good quality, but nothing fancy. I have my speakers positioned about 3.5' from my chair, on 30" stands.
As you can tell, my power requirements are quite modest. And in this setup the Topping shines. I'm no audiophile, so I'll limit my description of the sound quality to say that I can detect no sound distortion whatsoever, there's great stereo separation, and the bass, midrange, and treble frequencies are nicely balanced (after I turned the volume down on the subwoofer from the factory setting).Read more ›
I can't help but gosh about the Topping. It's an upgrade in every possible way. The quality is much higher, and the sound is much warmer. The depth and quality of the sound when listening to Mumford & Sons or M. Ward is absolutely amazing. The Lepia is very clean sounding, but the Topping is both very clean sounding AND very warm. The Topping also has a lot more bass, although neither amp will shake your house. That said, the Topping sounds MUCH better when listening to "Devil's Den" by Skrillex, and it sounds a lot cleaner at higher volume. Really well-recorded pieces like Norah Jone's "Don't Know Why" really flatter the Topping in a way that you don't get with the Lepai. Even older 80's stuff like Wang Chung's "Everybody Have Fun Tonight" - a song that makes my wife's eyes roll - sound much better with the Topping.
A few other small things to note about the Topping when compared to the Lepai. The volume knob is the Topping is more granular than Lepai. I couldn't turn the Lepai up past 3/4 before the amp started clipping.Read more ›
