This is an ambitious ask, not a bargain: at US$2,899, it sits well above the US$1,772 median for 58 recent comparable listings and just below the US$3,177 75th percentile. It is still within the observed market, but the premium needs to be justified by the exact version, condition, and completeness.
The GROOVE remains a highly regarded phono stage, known for exceptionally quiet, incisive replay, convincing timing, low-level detail, and a neutral, revealing presentation. A clean, original-owner example with its proper power supply, manual, packaging, and cartridge loading options could make the price defensible, particularly if it is a desirable upgraded variant. With condition listed as unknown, however, this is one to inspect carefully and negotiate toward the median unless the seller can document the specification and provenance.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
