I can echo the experience of the people above. I bought a Technics SU-Z600 from Shopgoodwill and it was severely damaged in shipping. Shopgoodwill gave me a full refund. Later I found another one on eBay that was damaged but in a different way. Both had damage on the plastic front panel. I combined the two and now have one in perfect shape. And it sounds really good. Very clear and detailed.
Bottom line: A wonderful amplifier that is very fragile.
