Offered is „HP4“ by EAR Yoshino as second-hand device from the category „Headphone Amplifier“ on audio-markt.de - the online market place for high-end. The advert with the number 9363527953 ends on 01.12.2026 at 13:21 o'clock.
“Good” condition makes the price easier to justify, but at €3,200 it is essentially a fair-market buy rather than a bargain. Your four comparable listings put the median at €3,119, with the middle 50% spanning €2,988–€3,277, so this sits comfortably inside the normal range, just above the median.
The HP4 remains a serious tube headphone amplifier: its four 6SL7 valves, transformer-coupled design, and separate high- and low-impedance outputs make it unusually versatile, while the Enhanced Triode Mode is known for a rich, highly resolving presentation. Four headphone outputs and balanced as well as RCA connectivity add real system value. At this price, confirm that the valves are healthy, all outputs are quiet, and the original accessories are present; if so, it is a worthwhile, enthusiast-grade purchase rather than an overpriced listing.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
