Disclaimer: NextDrive sent me Spectra X to test here at ohm, to blab about at Fauxtaku Lounge, and to review at Headfonia. I didn’t pay anything for it. Many thanks, NextDrive. I haven’t the foggiest idea of how much it will cost when available, but I do know that it will be available soon. For more information: Spectra X: The Portable Concert Hall.

Spectra X is better than is predecessor. It measures better, sends less amp noise to headphones, filters better, and comes in the same slim package. It’s quite the update/upgrade from the same company within a year. The good news is that the original Spectra was so good that if you have it, you’re golden. If you don’t, X is a worthy investment.
It is in particular a great upgrade over even good computer sound cards. In fact, depending on the source, it is more powerful than an Onkyo DP-S1, and tests almost as good. In fact, it pushes pretty close to Ryuzoh’s balanced Chord Mojo Kai mod.
There’s no noise from its amp even through Campfire Audio’s sensitive Atlas. It’s eminently suited for sensitive earphones, even at high listening volumes. At extremely high levels (testing levels), signal sheers are obvious and intense, but you’d never listen to those volume levels anyway. It powers an HD600 as well as an Onkyo DP-S1, which puts out a good 6dB more than an iPhone. If that means anything to you, good on me. If not, it’s loud enough for me and then some.
