This Meridian 551 listing at £486 is a strong deal, landing right at the 25th percentile of recent GBP comparables where the median sits at £497. You are securing a well-regarded integrated amplifier for less than the typical market floor, making this an excellent buying opportunity for anyone seeking British hi-fi DNA without the premium price tag.
The 551 is cherished for its clean, muscular sound and versatile architecture, notably its ability to function as a dedicated power amplifier when set to Type 4 for a transparent, uncolored drive. At this price point, the potential upside is significant; even if the unit lacks original accessories, the cost savings are substantial enough to warrant immediate inspection, as finding a clean example below £490 is rare in the current market.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
