Seller's Description

Stunning and rare complete with packaging

Our Thoughts RADAR AI

Excellent value at £19,990: against your comparable set, this sits just above the median of £18,404 and still well inside the normal band between £11,973 and £24,423, so it reads as a fair-to-good buy rather than an ambitious ask. For an excellent-condition pair, that’s a sensible place to be in the current used market.

These monos have a strong reputation for speed, control, and low-level refinement, which is exactly why they appeal to buyers chasing serious grip and transparency rather than warmth-for-warmth’s-sake. If the listing is complete and genuinely clean, the upside is getting a highly regarded reference-grade power amp at a price that isn’t chasing the top of the market.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Ypsilon

Ypsilon Electronics, founded in 1995 in Greece by sound engineers Dimitris Baklavas and Fanis Lagadinos, emerged from a shared passion for live music reproduction and electronics. Drawing on their extensive experience in live sound settings, the duo started with a hybrid integrated amplifier for the local market, evolving into a boutique workshop that blended traditional craftsmanship with innovative engineering. This Greek heritage underscores Ypsilon's commitment to natural sound and emotional musical connection, prioritizing fidelity to original recordings.

The brand specializes in high-end amplification and source components, including integrated and monoblock power amplifiers like the Phaethon hybrid and SET-100 Ultimate, preamplifiers such as the PST-100 with its transformer-based attenuation, CD players, and DACs. Their portfolio emphasizes meticulously handcrafted designs that integrate single-ended triode purity with robust power, alongside select cables and occasional analog partnerships, though speakers and headphones remain outside their core focus.

Positioned firmly in the ultra-high-end niche, Ypsilon commands respect among audiophiles and reviewers worldwide for state-of-the-art musicality and build quality. Frequently used as reference gear by loudspeaker designers and critics, its products grace exclusive listening rooms globally, embodying boutique excellence that delivers live-performance realism at any price point.
