What Apollon Audio does

Apollon Audio d.o.o. is a Slovenia-based (Maribor) private limited company founded in 2012 by Tibor Marksel that designs and handbuilds high-fidelity Class D audio amplifiers sold under its own brand. The product line spans monoblock, stereo, and multichannel (3 to 12 channels) configurations built around OEM Class D modules from Hypex (NCore NCx500, NC500, NC252MP, NC502MP, NC250MP, NC122MP, NC1200, NC2K), Purifi (Eigentakt 1ET400A, 1ET7040SA, 1ET9040BA, 1ET6525SA), and Icepower/Bang & Olufsen (AS1200–AS4800). The company layers proprietary value on top of these modules through its own Apollon Audio Input Buffer Board (Class A op-amps with DIP8 sockets supporting op-amp rolling, discrete Sparkos Labs voltage regulators, audiophile-grade polystyrene capacitors), custom-built Pure OFC copper binding posts with OCC 12AWG internal wiring, and handcrafted chassis with configurable finishes. The portfolio is structured into a standard Home Audio line, a Premium series (PET/PNC monoblocks at €2,495–€2,745), and multichannel/home-cinema configurations reaching €5,990.

The business operates as a pure direct-to-consumer manufacturer with no dealer, distributor, or retail layer. Amplifiers are built-to-order with lead times of 14 working days (stereo/monoblock), 21 working days (multichannel), and 30 working days (Premium); the company ships worldwide with insurance and tracking and accepts bank transfer, credit card, PayPal, and Bitcoin, with EU VAT added at checkout. Target segments are professional audio users (mixing/mastering/recording studios, PA applications) and high-end audiophiles, with secondary reach into home theater and immersive-audio (Dolby Atmos/DTS:X) installers. Reported performance metrics include THD+N as low as 0.00017% (1ET400A-based units), signal-to-noise ratios up to 135dB, high-current output to 48A, and wall-power consumption roughly one-third of conventional amplifiers. The company states 'thousands of amplifiers delivered worldwide' since founding, employs 1–10 people, has no external institutional funding, and remains fully founder-owned with Tibor Marksel as the only disclosed executive.

Core offering

Apollon Audio manufactures handbuilt, configurable Class D stereo, monoblock, and multichannel audio amplifiers (3-12 channels) based on Hypex, Purifi, and Icepower OEM modules. Each amplifier is paired with the company's proprietary Apollon Audio Class A input buffer board featuring user-swappable op-amps, and is built-to-order at the company's Slovenian facility and sold direct-to-consumer worldwide.

Product overview

Apollon Audio offers a comprehensive line of handbuilt Class D audio amplifiers organized into three tiers: standard Home Audio Amplifiers, Premium Amplifiers, and specialized multichannel configurations. The standard lineup includes stereo amplifiers (Purifi 1ET7040SA ST, Hypex NCx500 ST, Hypex NC252MP, NC502MP, and others), monoblock amplifiers (Purifi 1ET400A M, Purifi 1ET9040BA M, Hypex NC250MP, NC500MP, and SLM variants), and multichannel amplifiers (3-5 channel and 6-12 channel configurations using Purifi 1ET7040SA, 1ET400A, and Hypex NCx500, NC252MP, NC502MP modules). The Premium line features higher-end enclosures and build quality using Purifi 1ET7040SA (PET950), Purifi 1ET9040BA (PET1200), and Hypex NC1200/NC2K (PNC) modules. Icepower-based options (AS1200, AS2400, AS3600, AS4800) are also available. All amplifiers incorporate Apollon's custom input buffer boards with selectable op-amp configurations (OPA 1656, Sonic Imagery 994, or Sparkos Labs SS2590 PRO) enabling the 'Op Amp rolling' feature.

Broad incumbents

• Purifi Audio: Purifi supplies the Eigentakt modules Apollon's premium line is built around and is increasingly visible as a finished-product brand itself, representing both a dependency and an emerging competitive threat.
• Hypex Electronics: Hypex is Apollon's key OEM supplier of NCore modules but also sells finished amplifiers (e.g., Nilai, FusionAmp) directly, making it both a critical partner and a competitor encroaching on the same audiophile audience.
• NAD Electronics: NAD is an established consumer hi-fi brand with a broad Class D amplifier lineup (Masters and Classic series), serving audiophile and home theater buyers through dealer networks at scale that Apollon does not.
• ICEpower: ICEpower (a Bang & Olufsen subsidiary) supplies Class D modules to Apollon and also markets its own finished amplifier products to pro audio and consumer brands, making it a supplier-competitor in adjacent segments.

Direct peers

• Nord Acoustics: Nord Acoustics builds Class D amplifiers using Hypex NCore and Purifi Eigentakt modules with custom input buffer stages and configurable chassis options — a near-mirror of Apollon's value proposition at overlapping price points for audiophile buyers.
• Orchard Audio: Orchard Audio designs and sells high-performance Class D amplifiers and DACs based on Purifi modules, with a comparable emphasis on measured performance (THD, SNR) and a premium direct-to-consumer offering.
• Mola Mola: Mola Mola makes ultra-premium Class D amplifiers and DACs using Hypex and Purifi-derived platforms, competing for the same high-end audiophile buyer Apollon targets at the upper end of its PET and multichannel range.
• VTV Amplifier (VTVAMPS): VTV builds Purifi Eigentakt and Hypex NCore Class D amplifiers, including premium monoblocks with custom buffer stages, targeting the same audiophile buyer with handbuilt craftsmanship and DTC sales.
• AGD Productions: AGD produces high-end Class D and GaN-based monoblock and stereo amplifiers aimed at the audiophile market, competing at the top of the same premium Class D segment Apollon targets with its PET/Purifi-based products.
• Buckeye Amps: Buckeye Amps handbuilds Purifi and Hypex-based Class D amplifiers (including monoblocks and multichannel) for the audiophile market with a direct-to-consumer model, making it a direct competitor for the same Class D module supply chain.
