Extremely long delivery, but it is not a big problem. Packed well. I ordered finished assembled AMP, after i get it and tested this amp, i disassembled aluminium case to check IC's. IC's is ok, looks really original and not refurbished. PCB have a good quality, WIMA's looks original (case with bump logos), Yaohua transformer same as on fotos, all other IC's looks original and new. Amp works well, relay starting. Sounds good, tested with 250, 10, and 16 Ohm haedphones. Good seller, i'll buy some items again in this store.
