SW1X MPA V Monoblock Power
The SW1X MPA V is a revered mono power amplifier from a boutique UK brand known for pristine, musical sound, but this £25,000 asking price is genuinely ambitious compared to the typical used market. Based on three recent comparable GBP listings, the median used price is £10,793, with the 75th percentile at £13,623; this listing sits nearly double the 75th percentile, making it a risky overpay unless it includes rare extras or is in pristine original-owner condition.
That premium is only justifiable if the unit is flawless, includes the original power cables (which retail for £225–£450 per metre), and has been meticulously maintained by its sole owner. SW1X amplifiers are celebrated for their ability to deliver deep bass control and delicate treble without harshness, making them a top choice for high-end audiophiles seeking emotional engagement. However, without confirmation of pristine condition and full accessory inclusion, this listing reads as an overpriced gamble rather than a clear buying opportunity.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

Pronounced "As One eX Audio Design," the brand embodies Roschkow's vision as founder, managing director, and chief audio engineer to push the boundaries of musical authenticity. From its inception, SW1X has prioritized timeless, high-performance equipment over cost constraints, resurrecting the soul of recordings through meticulous craftsmanship.
The brand specializes in extreme, valve/tube-based audio components, including DACs like the DAC III and DAC II SPX, alongside amplifiers and integrated systems that ascend through performance levels from I to X. These designs eschew modern oversampling in favor of non-oversampling discrete R2R architectures, delivering fluid, organic sound. SW1X focuses on pure analog-like reproduction, with each tier refining circuits for greater lushness and expressiveness, appealing to purists seeking unadulterated musicality.
Positioned as a niche boutique in the high-end hi-fi market, SW1X commands a cult following among discerning audiophiles for its upbeat, soulful presentation that redefines digital and tube playback. Reviewed glowingly in specialist forums and publications, it stands apart from mass-market offerings, thriving in exclusive showrooms like Germany's Audio Creativ.
