The Sassy Mr. Lin showed off at last autumn’s Fujiya Avic headphone show laboured with hiss and noise. As a result, Phantasy stole the show. Not that Phantasy isn’t incredible. It is. Ducks all in a row it is the most memorable SET, and in my opinion, beautiful battery-powered valve amp I’ve yet tried. I have a feeling that it will feature loudly in 2016’s roundup.
Unlike Phantasy’s transformer-coupled design, Sassy is a hybrid design with a solid state output stage. As a result its sound is familiar where Phantasy’s is unique. Sassy is warmer, drier, and measurably better-suited to a wide range of headphones and earphones. It is compact, and while not as painstakingly designed, eminently utilitarian.
And then there’s its name.
But Phantasy is sassier than is Sassy. Sassy’s laissez-faire warmth, and more equitable frequency response, is stable, wholesome, nutritive. To pull another meaningless adjective from between my pelvis bone, I will call it chocolatey. As long as we’re not talking addiction (because, at least for me, Phantasy is far more addictive), chocolatey is actually a pretty good word.
The ODE has the following to say about the word sassy.
adjective (sassier, sassiest) informal
lively, bold, and full of spirit; cheeky: Toni was smart and sassy and liked to pretend she was a hard nut.
While I don’t understand what a ‘hard nut’ is, I reckon I get it. Sassy means anything but plaintive. The ODE definition is the measure against I will stretch Sassy’s various tones, angles, and functional elements to decide whether or not Phatlab Audio screwed the marketing pooch.
I kind of have to start with its knob. It’s a knob. It’s solid, well aligned, and tied to an accurate left/right spread. Unlike Phantasy’s brilliantly machined grippy, and anchor-like thing, Sassy’s is pretty plane. When prised to the right, or rotated one-handed, it budges enough to rub against the nearest roll cage. Like Phantasy, you can slide your finger across it to adjust the volume, but Sassy’s is typically smooth-moving, not Mazak CNC machine-like silky like Phantasy’s.
Speaking of roll cages, does Sassy not borrow a little from the Sony PHA-3? I’ve come around to the roll cage since ragging on it when the PHA-3 was first introduced. My guess is that it prevents inadvertent volume changes when you’ve wedged the thing into your jeans. Actually – and it would be remiss of me not to mention this – Sassy doesn’t get hot, so why not shove it in there?
Phantasy-level quality 6,3mm and 3,5mm jacks line Sassy’s front. And, the two appear to be spaced just as widely one from the other. The 6,3mm jack sits flush with the chassis. About 8mm sit between it and the left-hand roll cage. If you’re using a 3,5mm to 6,3mm step-up adapter, you may have a Dickens of a time cleaving the two without lifting Sassy up. The 3,5mm input jack sits in a shallow well with enough space to accommodate fat plugs. Sassy’s 5V charging port is every bit as good as Phantasy’s is. It’s every bit as deep, every bit as utilitarian and functionally designed. No mains adapter required. How sassy is that?
What’s kind of sassy about Sassy is toaster oven eyes. They glow all hot and Cylon from the moment you switch on the battery mains. They’re behind a lovely bit of rear-printed glass. The printing on that glass is a marked step down from the precise and clear text adorning Phantasy. It’s functional, legible, but not pretty. It is, however, a bit alien.
That’s kinda sassy.
Sassy’s feet are just as solidly inset, it’s chassis nearly as rigid, and it sits perfectly flat on a perfectly flat surface. Its fastening hardware is high quality and strip resistant. Not sassy at all.
Like Phantasy, Sassy takes a while to warm up. Unplug a headphone, plug a new one in, and it rings like the the fading undulations of a high hat. It’s a ring that you’ll hear for less than a minute through most headphones. It’s neither obnoxious, nor is it comforting. It’s there. It goes: hey geezer! you’re listening to tubes! before fading to black. You’ll forget about it until you plug a new pair in, or turn the amp off and then on again.
Sassy’s shape and UI is a marked step down from Phantasy’s. One-handed pot operation? Can do, but grunt work is required. And again, you’ll grind the pot on its roll cage. Overall, it’s a good UI, but is neither as natural, nor as smooth to operate as Phantasy’s. And while Sassy’s build quality stands up to the latest ALO’s, it doesn’t hold a candle to the CDM’s concise, Bauhaus shape and branding, but then again, neither does Phantasy’s. Its two-tone case is attractive, and the glass up top promises fun viewing. But why do the phatlab logo and Sassy’s explanatory text obstruct part of the window when there’s ample room above and below?
