Parallel Op-Amps by Virtual HiFi

Recently, discrete Op Amps became very popular.

Because they’re built from separate components, many people believe they sound better than regular integrated Op Amps (the small chips used in most audio gear).

And yes — good discrete Op Amps can sound fantastic. But there’s another way to get incredible performance.

The Smart Trick: Paralleling Op Amps
We use the best modern ones available — and connect several of them together in parallel.
 
Why? Because when you combine them:
  • They deliver more power
  • They control the signal better
  • Noise goes down
  • The sound becomes bigger, stronger, and more dynamic
  • You get more bass control, wider soundstage, better presence, and a more natural feel.
And the improvement is huge.
In many cases, two top-quality integrated Op Amps working together can outperform a typical discrete design.
 


Why make them parallel?  Because when you combine them:
  • They deliver more power
  • They control the signal better
  • Noise goes down
  • The sound becomes bigger, stronger, and more dynamic
  • You get more bass control, wider soundstage, better presence, and a more natural feel.
And the improvement is huge.
In many cases, two top-quality integrated Op Amps working together can outperform a typical discrete design.
 

So What’s the Catch? 
  • It costs more (you’re using multiple chips instead of one)
  • It takes more space
  • It uses more power
  • It produces more heat
That means the circuit must be designed properly to handle the extra load.If it is — the results are exceptional. 
 


Most audio devices use voltage regulators rated between 500 mA and 1500 mA.

That means they already have more than enough current capacity to comfortably power:

Up to 4 Supersonic V1/V2 Op-Amps,    2 Hypersonic Op-Amps

No special modifications. No power supply upgrades
.
In most well-designed equipment, they can be driven with ease.

HYPERSONIC - Dual Op Amp   

Sound Character -  This Op-Amp has all of the dynamics and openness of the Supersonic V2 and adds additional layer of dense, rich sound with even more present bass and immersion in the midrange. This it the sweet spot and the most neutral, organic and immersive Op Amp that you can use.

WARNING!!!
Do not use in closed enclosures. Do not use more than 4 Hypersonic Op-Amps per device. This Op-Amp draws 0.17 Amp of current. It means that using more than four of those Op-Amps might result in the damage or overheating of the device you are using the Hypersonic's in. Use up to four per device and make sure there is proper ventilation.

Hypersonic Mono   

This is a Single version of the Hypersonic. It is one channel Op-Amp and is a half of Hypersonic Dual.  

Sound Character -  The sound is full, dense, with deep and well controlled bass. The midrange is organic and with great presence. High frequencies are detailed and with slight relaxation. All that combined with the wide soundstage makes it The King of Balance

Single / Mono does not mean it has to be used in Mono-block amplifiers but it relates to internal circuitry. 99% of times you need the Supersonic V1, Supersonic V2 or the Hypersonic. Hypersonic Mono will work in very specific devices.
