Nimitra Computer Audio Server receives AudioStream’s Greatest Bits Award

 in Review

Today AudioStream has published a review for Nimitra Computer Audio Server, the first physical hardware product from Fidelizer. I’m very excited in this month because there’s a few reviews about Nimitra rolling out in this month.

The first ones in this month was written Mr. Steven Plaskin, Fidelizer supporter since early days. He kindly accepted my review request about Nimitra despite being so busy for months. It took a while but he eventually published Nimitra review in good timing before X’Mas.

There’s a bit of pieces about sound impressions from Nimitra here and there in his review so I recommend to read Fidelizer Nimitra Computer Audio Server review as whole article with good music. Here’s one of interesting parts he mentioned about Nimitra’s sound quality.

Nimitra used my MSB Technology USB ASIO driver for full support of PCM files up to 24/384kHz and DSD256. Function was flawless and the sound was excellent. Nimitra just sounded smooth and rich with the Analog DAC. I felt the overall sound was easy to listen to for extended periods and was most definitely superior to what I could achieve with an unmodified OS PC or Mac. Overall detail and focus were first-rate with the Nimitra. In some ways, the Nimitra reminded me of the Playback Designs Syrah Server in terms of its excellent playback qualities.

In my surprise, this review comes with unexpected bonus. Nimitra receives AudioStream’s Greatest Bits award. It’s the first award I received for Nimitra product. Receiving award means a lot to infamous product owner like me. It could be one of my best X’Mas present since founding Fidelizer. 🙂

Why does external USB interface sounds better than internal USB interface?

 in Article

Thinking logically, internal USB interface should have lesser chain of connection, shorter I2S connection to DAC without encapsulation on AES/SPDIF and stuff. My friend conduct some listening tests with Eximus DP1 and Stello U3. We found that using Stello U3 as external interface to AES/Coaxial input sounds better than internal USB interface. Both U3 and DP’s internal USB audio should have about the same quality. They even share the same driver and firmware.

After further tests with USB isolator and noise filter on tested computer machine, we found they minimized the difference between internal and external USB interfaces significantly. We could say that the reason why internal USB interface sounds worse is because DAC itself gets pollution from direct contact with computer audio source. By using external USB interface, DAC itself receives signal from encapsulated stream from USB interface box isolating pollution from USB connection.

However, it’s unavoidable for DSD to be played from direct USB connection. I think it’s important to reduce the pollution in computer audio source or suppress its effects with isolator or noise filter with optimal implementation.
