Rare Qinpu D-1 Tube Amplifier + S-2 Speakers + SW-4 Subwoofe

Price: €650 – Open to serious offers from €550 and above

This is a collector’s piece and a true gem for audiophiles or music lovers looking for a high-quality desktop setup. The Qinpu D-1 is not just a mini amplifier, it’s a compact Class A, full tube masterpiece with incredible warmth, rich mids, and an unmistakable vintage charm.

I bought this set new six years ago, and it has been barely used, it mostly sat in a cabinet, protected and unused. The amplifier is in perfect working condition, with only minimal cosmetic signs of use. The system comes complete with:

• Qinpu D-1 Tube Amplifier (Military Green Finish)
• Qinpu S-2 Two-Way Horn Speakers
• Qinpu SW-4 Mini Subwoofer

(Please note: one of the speaker woofers occasionally crackles at high volume, likely fixable or replaceable. The other speaker has a tiny bump on the central dome, which does not affect sound performance at all)

This set is extremely rare and hard to find, especially in Europe. It’s ideal for anyone who wants true hi-fi listening at their desk, with the elegance and soul only a tube amp can deliver.
