EF499 and EF500: Hifiman's New Twins Take on Desktop Audio

The EF499 takes a slightly different tack, opting for a Philips R2R DAC. This is a bit of a nod to the old-school, giving your music a warmer, more 'analog' vibe that some folks really dig. It's also designed to be a headphone stand, keeping that dual-purpose theme going.

Both models are pretty compact, designed to not hog too much space on your desk. They've got all the connections most folks would need, like balanced and unbalanced outputs, and a switch for toggling between digital and analog modes. They're built to last too, with features like an independent power supply and a case design that keeps things cool.

Price-wise, the EF499 is the more wallet-friendly option at $299, while the EF500 will set you back a bit more at $459. But what's the word on the street? Well, without diving into individual opinions, the general vibe is that these DAC/amps are hitting the right notes. The EF499, with its classic DAC chip, is getting nods for its smooth and potent sound, appealing to those who have a soft spot for the warmth of vintage audio gear. The EF500, meanwhile, is earning props for its precision and clarity, making it a strong contender even among pricier options.

In short, Hifiman's latest are shaping up to be solid picks for anyone looking to up their desktop audio game without cluttering up their space or emptying their bank account. Whether you're after that pristine, accurate sound or something with a bit more old-school warmth, there's something here that's likely to hit the spot.
