Timing matters a bit here because the Mogwai SE Rev 3 is a current-ish used piece rather than some obsolete tube amp, so you’re buying into a still-relevant design — but at US$3,500, this is clearly ambitious versus the recent used comps, which center at US$1,766 with the upper quartile at US$2,324. It’s well above the 75th percentile, so this is not a bargain-priced grab.
What makes it interesting is the combo of a respected transformer-coupled tube headphone amp and the fact that it’s apparently low-hours with a loaded tube bundle, which can add real value if the tubes are known-good and desirable. For a buyer who specifically wants the Mogwai sound and would otherwise spend more on tubes, the package may still make sense — but you should verify exactly which tubes are included and whether the amp has been serviced, since the premium only works if the accessory value is real.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Ampsandsound emerged as a small family business in Southern California, rooted in a passion for midcentury American vacuum tube amplifiers. Founded by engineer-proprietor Justin Weber, the company draws heritage from legendary designs of the 1950s, such as those by Harmon Kardon’s Stu Hegeman, blending traditional tube circuits with modern material science. Handmade in limited runs, its origins reflect a DIY ethos that prioritizes timeless concepts over mass production.
The brand focuses primarily on high-performance tube amplifiers for both headphones and speakers, with flagship models like the Bigger Ben, Kenzie, Mogwai, Agartha, and Bryce Monos earning acclaim. Many headphone amps feature rear loudspeaker binding posts, underscoring Weber’s dual commitment to personal hi-fi listening and two-channel systems. While speakers form part of its lineup—echoing Klipsch-style horn efficiency—ampsandsound avoids broader categories like DACs, turntables, headphones, or cables, keeping its scope tightly curated.
Positioned as a niche boutique in the high-end market, ampsandsound commands a devoted following among tube enthusiasts and headphone aficionados for its engaging, superior sound at accessible prices. Well-regarded in circles like Head-Fi and Stereophile, it thrives on Weber’s hands-on craftsmanship rather than mainstream volume, appealing to discerning buyers seeking authentic, low-power tube magic over polished corporate offerings.
