Seller's Description

Stunning and rare complete with packaging

Our Thoughts RADAR AI

Excellent condition helps here, but at £21,900 this sits above the £18,360 median and between the £12,048 and £24,364 spread, so it reads as a solid but still somewhat ambitious ask rather than a standout bargain. It’s not out of line for a premium monoblock pair in tidy shape, but I’d want the buyer to see it as paying for confidence and presentation, not a hidden discount.

That said, these are highly regarded for their grip, scale and sheer composure with difficult loudspeakers, so a clean pair can be a very worthwhile buy if the rest of the chain justifies it. The upside here is mainly in condition: excellent cosmetics, careful ownership and complete, ready-to-run presentation matter a lot on something this serious; if those boxes are ticked, the price is defensible.

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.
