“There is no funny reconstruction filter that is said to sound better. The Topping has a high-performance FIR that is flat to 20kHz and has a sharp stopband down 90dB. The output at 0 dBFS comes in at 2VRMS, the industry standard. Channels were remarkably well matched in all tests. It is 0.5dB down at 80kHz!!

I have a complete set of measurements below but nothing on the market at $90 will produce numbers within an order of magnitude of what I measured above. You could stop here and run out and purchase one but I’d advise you to please read my next section on shopping advice when purchasing small brands from the Far East first.”

“Yes, the Hugo 2 presents an analytical sound especially against its predecessor. But I don’t find it too analytical, at least not that much like the people say. To me it has great dynamism, very sharp separation and sublime transparency. But there’s a sense of musicality in it, and if you pair it with a warmer headphone/IEM, it is simply wonderful to listen to.

Overall, the Hugo 2 makes you think about the “taps” that Rob talks about. The more taps you have, the better sound you will hear. It has better bass decay, a blacker background, better imaging and better micro detail reproduction. The timbre is more realistic as well, which I put a lot of emphasis on because it’s one of the most important aspects.

But among all of those improvements, the most striking difference when I switch to Hugo 2 is the air. The original can’t give you that, as it’s made of romanticism and intimacy. It has that organic gene, which you can’t change or alter in any way. And that’s totally fine. You win some you lose some, it’s normal.”

” Yes, the Vitus MP-201 is a masterpiece product as the name states but it can only work within the limitations of the system it sits at the heart of and this means that its likely destinations are high-end systems, or in other words, expensive systems assembled by those fortunate enough to be able to afford them. You are going to need to make sure that every detail has been thought through. This means from the router onwards. You really need to give the conductor the right tools and there are no short cuts. I have heard so many systems that cost more than a house that failed to deliver anything other than a loud and rather tiring facsimile of music. Brimmed full of the most outrageous detail but totally lacking in soul or humanity. Digital-based music can still be like this. It has always been that way since Digital began to show its (then) ugly face to the world through recordings on vinyl. I read the reviews and rushed out and bought this early stuff and ended up hating it, for years in fact. Early CD too was shockingly bad. But, where we are now is light years away from those days. What hasn’t changed is that realising the potential out of any system includes the painstaking business of considering the infrastructure that surrounds the electronics themselves.”

“While that might sound relatively modest compared to smaller desktop amps which now routinely offer several full watts of power, there’s been a bit of confusion about what exactly the result of that is. More power does not determine a system’s volume – that is in fact determined by gain. A lower powered amp will actually sound louder than a higher powered one if it has more gain at a given input. Power is more important in determining what the maximum current or voltage a device can swing into a transducer when hit with musical peaks as well as how loud waveforms are. So, think of power as being a rough indicator of how dynamic a system can be, and gain as determining its relative loudness when listening. I’m grossly oversimplifying and all the electrical engineers are squirming, but I think you get the point.”
