Schiit's solid-state 6SN7

"Solid-state tube replacements aren’t a new idea. However, most of them go on and on about how they sound “just like tubes.” We’re not going to say that. We will say that they sound very good. We will also say they have lower distortion than tubes, though with a similar overall profile. Beyond that, it’s up to your own perceptions."

So...they're tube-shaped? Is that what we're all secretly hankering for? Tube-shaped objects? Not that there's anything wrong with that. 

Whatever this product is, specifically, there are a number of things that are true about Schiit -- they try new things, they don't lie, and they don't take themselves too seriously. Their stuff is well made and they have good customer service.
