Discrete? Surely we meant to say discreet?
The Novo is both: it’s discreetly small – a definite miniature in a world full of behemoths; and it’s discrete because that’s the circuitry it uses – discrete transistors.
Discrete transistors? Yes, you heard right! Most budget headphone amplifiers let an op-amp do all the work. We wanted to show that we’re capable of more than that.
The result is a very capable headphone amplifier, so capable that headphone manufacturer Shure bought some and Sennheiser featured it in a promotional video driving its flagship headphone.
You may never have heard of the Novo headphone amplifier before today, but now you have. It’s definitely worth your consideration if you’re after a budget headphone amp – a hi-fi amp for headphones!
