Looking for the quintessential Schiit schwag? Look no further. Here’s a set of four PC board coasters, perfect for resting your drink on. Well, at least if you don’t mind maybe still ruining the nice wood finish underneath the coaster, because these things have holes in them. Yes, that’s right—these coasters are made out of PC board material. And yes, that’s right, they have a PC board pattern etched on them. It’s even plated in gold (technically, Electroless Nickel Immersion Gold, or ENIG.) Aaaannnddd…you can build these coasters into a working hybrid headphone amp if you’re a super-mega-geek like us. The docs are available at schiit.com/coaster. Have fun!

When used as a coaster: Frequency Response: none Power Output: zero THD: huhwhut? IMD: I dunno SNR: nope Crosstalk: I’ll guess with you Output Impedance: noneInput Impedance: you’re kidding, right? Gain: none Topology: standard horizontal coaster Protection: none Power Supply: NA Power Consumption: zero (very green!) Size: 3.5” diameter x 0.062” thick Weight: about 1 oz or maybe less (come on, it’s a coaster, you think we weighed it?) When built as an amp (schiit.com/coaster): Frequency Response: not terrible, but not exciting (like 10-100K, -1dB or so) Power Output: much less than anything else we make (like, less than Fulla 2, maybe 400mW into 32 ohms, all in, 10% THD or so) THD: about 0.5% at 1V RMS (6418 tubes) or about 1.5% at 1V RMS (6088 tubes) IMD: didn’t bother measuring, this amp ain’t about measurement SNR: not CIEM friendly, about 90-95dB or so referenced to 1V, A weighted, depends a bit on the tubes Crosstalk: yes, about -75dB 20-20k Output Impedance: about 8 ohms (yes, 8, not 0.8, not 0.08), in case you didn’t get the memo, this ain’t a high-performance amp Input Impedance: 50k Gain: about 3-4 (depends on tube) Topology: subminiature pentode in triode-strapped mode, discrete Class AB output stage Protection: time delayed relay mute on startup Power Supply: uses standard Schiit 16VAC wall-wart Power Consumption: about 2W Size: 3.5” diameter x 1.25” thick at highest point. Or so. Weight: maybe 4-5 ounces, unless you went crazy on audiophile caps or something
