What causes audible differences in network cables?

We round off our little investigation into network cables with a listening test and a clear conclusion. As promised we subjected the network plugs to a listening test and listened to three different configurations: shielding fixed on one side, shielding fixed on two sides and double shielded (and both sides connected). Do we hear differences? […]

Review – ten connectors for network cables – Let’s get connected

We test all sorts of things at Alpha Audio. Your editor also a lot in the area of network connectivity. Think cables, network interfaces, converters from copper to fiber, switches, et cetera. However, we’ve never looked at network plugs – connectors. Yes: very nerdy. But useful for the DIY’er. Because you can be sure that […]

Review Jcat NET CARD XE – Optimo 3 Duo – Clean Stream

It has been quite a few years since we tested the first “audiophile” plug-in card. At the time we did have our doubts, to be honest, because data is data right? Yes… that is certainly true. But now we know better. It’s not about the data, but about how clean that data comes in. Free […]

Bluesound NODE

Review Bluesound NODE streamer (2021)

After nine years in the market, Bluesound comes with the new NODE. Are we going back in time? No. Bluesound is dropping the numbers for this latest generation – officially Gen 3. It’s now just Bluesound NODE, POWERNODE, et cetera. Not a lot just seems to have changed. But appearances are deceiving! We take a […]

Aurender N20

Review Aurender N20 streamer – server

Digital is digital. A 1 is a 1 and a 0 is a 0. Period. Right? Well… partly. And in the ideal world where jitter and noise are not a factor, they will be. But we don’t live in the ideal world. (Unfortunately we don’t in a lot of ways). And that makes that there […]

Multitest – Endgame Audio – The ultimate streamer

On Mother’s Day (at least in the Netherlands) – May 9, 2021 – we at Alpha Audio held a live stream event featuring three insanely beautiful streamers. Top of the bill: the MSB Discrete DAC with Renderer module, the Grimm Audio MU-1 with Mola Mola Tambaqui dac and the Naim ND555 with PS555 power supply. […]

Review PD power supply modification Bluesound Node 2i

Earlier this week we made an install guide around a custom power supply for the Bluesound Node 2i. We also put some samples online so you can hear what a difference it can make in combination with a Sbooster BOTW 5 volt power supply. In the meantime, we’ve done some more listening. We will share […]

Review Matrix Audio Mini i-pro 3

In recent years we have seen quite a few Chinese brands appear on the European market, some of which are already receiving support from Dutch importers. Only a handful are really worth spending our precious time on and today the honor goes to Matrix Audio, a young company from Xi’an that was started in 2013 […]

Multitest – The best switch for streaming audio

Data is data… A 1 is a 1 and a 0 is a 0. Right as rain. So why are we testing network switches? They don’t make data errors, do they? After all, there are ancient protocols for data transmission. Protocols that have proven themselves for decades. True too… But there are more factors that […]

Review Sonnet Hermes streamer

We have already written a lot about Metrum Acoustics, the dac designs and the designer: Cees Ruijtenberg. It caused some confusion when the name Metrum Acoustics disappeared from the scene and Sonnet Audio saw the light of day. Rest assured: both brands give support. We therefore write with confidence about the new streamer: the Sonnet […]
