Traded a pair of AD900 (friend's) for Manvin's A900. Very understanding and patient with my friend's busy schedule to ship the phones out to him. Prompt courteous communication, and he shipped the phones when he said he would. They arrived quickly, packed well and were in superb condition. All around great guy and asset to Head-Fi, wouldn't hestitate to do business with again !
I just bought a Pimeta amp from Manvin (m3ta1head). His communication was so fast -- he would reply to my messages within an hour about. He shipped it really fast too. I paid and he shipped it the next day. Then the next day it was in my hands. Good condition, just as described. And very well packaged. A great deal. Thanks!
