Happy happy without any clouds? Having recently concluded a trio of headfi amp reviews—Burson Soloist, HifiMan EF-6, Linnenberg Audio u:c:a—my exposure standards were pegged solidly at the $1.000 mark and educated by beefy linear power supplies and up to 4 watts of high-testosterone output power. Add Linnenberg's and Burson's 'we don't use no stinking IC op amps' campaigns. One could easily feel set up just so to regard the veritably op-amp studded RxMk3-b with haughty suspicion. True, a Soloist sounds even bigger and more effortless which perhaps involves the absence of feedback (IC op amps use a lot). That's a bit like moving from high-quality 2-way monitor speakers to floorstanding three-ways with 10-inch woofers. The latter move more air. But it's mostly really just the sense of scale which going mobile, miniaturized and battery-powered impacts. Raw resolution, SPL and general sound quality transition surprisingly intact. It's simply a smaller experience. That's perhaps perfectly fittingly. After all in the outdoors this ear experience will be shared with your visual sense if for no other reason than personal safety and keeping your wits about you.
