Sparkos Labs SS78 & SS79 Discrete Voltage Regulators
Providing power to the Op Amps and the PURIFI 1ET400A, the Sparkos Labs SS78 and SS79Discrete Voltage Regulators play a key role for ultra low noise and fast transient responses on our custom input buffer boards for the PURIFI 1ET400A based amplifier.They are responsible for improved low level listening ability, far superior 3D soundstage and high frequency details. The difference is mostly noticeable at higher volumes, where the clarity remains on higher levels and with ample details and dynamics even at low listening levels.
The Sparkos Labs SS78 and SS79 Discrete Voltage regulators bring many advantages compared with standard monolithic designs where large capacitors for heavy filtering on the internal voltage can not be implemented. The fully discrete erorr amplifier on the device gives the ability for amazingly high input rejection and unique compensation techniques that are not possible to implement with regular monolithic IC error amplifiers.

What our clients say about the PURIFI 1ET400A
We are humble and do not like to brag, so below you can find just a few selected testimonials from our happy clients that own our amplifier built around the PURIFI 1ET400A amplifier modules.
“I had a pleasant surprise this evening. I had the visit of Johnny Cash and June Carter at my place and they performed an outstanding live performance. My all body was shaking and thrilled by the flow or their amazing voices and the rhythm of Johnny’s guitar.
This amazing experience was possible thanks to my customized NC1200SL I just received this morning. It feels like a quality product. It looks and sounds great. And it should further improve after few more days of listening.
The Apollon Team did a great job. The custom 8 connectors are perfect to bi-wire my B&W CM10. I was looking for the best value for money amplifier based on the Hypex NCore.
I am glad I found Apollon Audio.
I have to go. More guests are coming. The Folsom prison is inviting itself to my place. “
Nicolas Payen (Singapore)
“I’ve had the amp for about a week and a half now and I’m enjoying it quite a bit. It’s opening up nicely and the depth and detail are excellent. I’ve had to adjust my subs (dual Rythmik F15s) down a bit because, I believe, my Tylers are now being driven more to their potential. Excited to hear if things open up even more.
Very happy so far with my purchase. Thanks again!”
“The amp sounds amazing. Everything you said about the amp is true. Super accurate, super precise and fast. I rediscovered my NS10s.”
“I received the amplifiers, I thank you again for the quality of manufacture. I will do a very good publicity for Apollon Audio.”
