This is a niche, serious valve headphone amp, and the asking price of £1,537 looks broadly fair rather than cheap. The closest public pricing trail I can anchor is Abbas’s own OTL headphone amp being positioned around the £800–£900 level at launch, while used Abbas pieces from the same ecosystem often land in the roughly £700–£1,900 band depending on model and condition, so £1,537 sits in the sensible middle for a higher-end example.
What makes it appealing is the transformerless tube design: these usually shine with high-impedance headphones, offering a big, open, immediate sound with strong tone and good drive. Abbas gear is also a bit of a cult buy, so good examples can be worth paying for if the build is clean and the supply is complete. At this price, I’d want confirmation of tube health, low hum, and whether any matched tubes or original packaging are included, but nothing here screams overpriced.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Abbas Esoteric Audio is a small, highly idiosyncratic hi-fi brand based in Ukraine, founded by Abbas, a musician and self-taught electronics designer. Publicly available information suggests the business evolved from custom and DIY-style experimentation into a low-volume specialist manufacturer, rather than a conventional mass-market audio company. Its exact founding year is not clearly verifiable from readily available sources, but it has been active for years and has built a strong cult following among enthusiasts.
The brand is best known for digital audio components, especially DACs, digital-to-digital converters, and USB-to-S/PDIF interfaces. It also appears to produce related source components and associated power-supply or accessory designs, with a strong emphasis on unconventional engineering choices, vintage parts, and material science rather than mainstream feature sets. Abbas’s products are often discussed alongside non-oversampling and classic multibit DAC architecture, particularly Philips TDA1541A-based designs.
In the market, Abbas sits firmly in the niche boutique end of high-end audio. It is not a broad mid-tier brand; instead, it appeals to experienced buyers who value rarity, hand-built construction, and a distinctive sonic philosophy. Among digital-source enthusiasts, it has a reputation for originality and strong character, though its appeal is more specialized than universal.
