The iMac Pro generally impresses me: fast, quiet, powerful, and great screen. It’s made faster high-end macro photography editing by at least 3 hours per image. Not bad.

RMAA: iPhone SE 24-bit

January 13, 2017 ohm

So, the iPhone SE keeps test results within a decibel of both the iPhone 6 and the Apple Lightning to 3,5mm headphone adapter. It has a wonderfully low noise floor, shows reasonable stability under load, and at high volumes, presses into mid-tier audiophile DAP performance.

Last week my iPhone SE came in. And though she ordered it late, so did my wife’s iPhone 7. While the SE is gloriously understated, and wieldy, the 7 is a return to what I consider Apple’s most horrific modern design. Its largest makeover is the removal of a headphone jack. Next is the smoothing out of its camera hump, a consequence of which is that iPhone 6-compatible cases half cover up the iPhone 7’s camera and flash superstructure.

RMAA: Apple's Lightning to 3,5 mm Headphone Jack Adapter 24-bit

Purchased separately to the iPhone 7, this adapter costs 9$ USD. It hisses less than an Astell&Kern AK70 and outputs a stabler signal under load than both the AK70 and an iPhone 6. It sustains quality signals under load better than many DAPs and most iPhones I’ve tested in many years, all while spitting output voltage similar near the level of an iPhone 6.

While I've used cases (or makeshift substitutes) since 2007, I've never seriously considered a charging case. I don't need the bulk. And, my Quad Lock fastens to a bicycle like a camera lens to a camera. Amazing.

Being an Apple fan has its ups: the iPhone 4, iMac, iPad, and its downs: Apple Hifi, long Mac Pro cycles, and the iPhone 6.

Since early 2013 my iMac has shepherded every last yenny into my business. And though I trust it almost implicitly in matters of heavy image processing, I don’t plug my headphones into it. Why? Two reasons:
