Announcing Hypex Nilai DIY Kits—-now available!

Warren Coleman — Wed, 28 Dec 2022 18:48:49 +0000

We realize that for some more than half the fun is building the product….and Hypex is here to help! The Nilai is Hypex’s cutting edge technology for DIY Class D amps. The successor to the classic NC400 is now here in mono and stereo kit form.

In addition, there is a super low noise, fully balanced preamplifier kit available to complement all of the amps we sell. The preamp will soon offer optional DAC and phono stages that we will have as upgrades and future options. It has a really neat OLED display and includes a remote.

Limited stock is available now!

Tube Buffer for the Purifi 1ET-7040SA High Power Module

Warren Coleman — Mon, 26 Dec 2022 00:56:29 +0000

We are excited to release VTV Tube Buffer for the Purifi 1ET-7040SA high power module.

Music sounds smooth, open and natural through the combination of the 1ET-7040SA and VTV tube buffer. We have many discrete opamps to choose from when ordering.

Enhancements to the new tube buffer include:

—-improved DC offset stability

—-visual display of power and ready indicators

—-reduced noise floor

VTV GaN Amplifier

There is a lot of excitement around the use of GaNFET based Class D amps. Now we have an amplifier option that combines a GaNFET output stage with an all DIGITAL architecture. This means that PCM is directly converted by software to PWM and delivered to the GaNFET output stage. With no feedback, the amp has a very musical quality with expansive soundstage.

FEATURES:

Power output: 300W into 8 ohms, 390 W into 4 ohms

Zero Global Feedback

0.1% THD+N (8 ohm 1W)

Amp module deigned and built by EAS

Combine this amplifier with a streaming source that has a digital volume control like ROON

An elegantly simple high -end solution for an all digital music collection.

We have a limited number for shipment now

The

New Hypex NCx500OEM

Warren Coleman — Thu, 01 Dec 2022 01:01:01 +0000

We received two new Hyoex NCx500OEM modules and have been really excited to try them. The new Hypex NCx500module has its own buffer featuring the TI1612OPA opamp. In addition you can see the high performance voltage regulators Hypex includes as standard equipment. It also has an engaged LED indicator on the end of the board.

To take full advantage of the new board we developed a new front-end. We added RFI decoupling and dialed the input impedance to a friendly 47k. There are some helpful status LEDs on our board.

Before running any listening tests we ran the new boards through our Audio Precision 5x system to get a feel for the specs. Wow! At 50% power (approx 180W @8 ohms) we measured 0.0001 % distortion….among the lowest we have ever measured.

We then tried the new modules running midrange in our active system on Volt 3.5” domed mid (500-4K). When compared to the Purifi 1ET-7040SA running New ClassD opamp, the midrange showed similar delicacy and smoothness….impressive given it can deliver twice the power. We will do more in-depth comparisons soon.

We have the new modules on order and expect them soon!
