Som rubrik Monoblock av det bättre slaget. Nyservad och checkad av känd rörtekniker (Stockholm). Det går bra att fråga vem. Funkar som det skall. https://www.soundstagenetwork.com/revequip/atmasphere_m60mkii.htm
Condition is unknown, but at kr 25,000 SEK this lands well below the kr 33,002 SEK 25th percentile and far under the kr 48,481 SEK median for recent SEK comparables, so it reads as a strong bargain rather than just a fair ask. For a pair of M-60 mk 2 monoblocks, that is an unusually buyer-friendly entry point if the amps are complete and working.
These Atma-Sphere amps are well regarded for their open, fast, highly transparent sound, and the design has real appeal for buyers who value purity over brute-force “muscle amp” character. The upside here is obvious: if they’re healthy and include the needed bits, you’re getting a respected tube monoblock set at a price that leaves room for service if needed.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Atma-Sphere Music Systems traces its roots to 1976, when founder and CEO Ralph Karsten established the company in Saint Paul, Minnesota, USA. From its inception, this small boutique operation has championed handmade vacuum tube amplifiers, pioneering innovations like the world's first reliable Output TransformerLess (OTL) designs and balanced-line products, including the landmark MP-1 preamplifier. Karsten's patented Circlotronic circuit and direct-coupled OTL output stages set the brand apart, embodying a commitment to enduring quality under the "Twenty-year Rule," which prioritizes components lasting decades without major service.
The brand focuses exclusively on high-end amplifiers, with its core reputation built on pure Class A OTL tube monoblocks and stereos, all hand-wired without circuit boards for superior quietness and dynamics. While preamplifiers like the MP-1 complement the lineup, Atma-Sphere avoids speakers, turntables, DACs, headphones, or cables, recently expanding into efficient solid-state Class D models that align with its efficiency goals without diluting its tube heritage.
Positioned firmly in the ultra-high-end niche, Atma-Sphere commands respect among discerning audiophiles for its transparent, powerful sound and battle-tested reliability, earning accolades across decades. These aren't mass-market or mid-tier offerings but collector-grade pieces for those seeking transformative tube performance in a market dominated by fleeting trends.
