On a recent US trip I got a VTV power amp. (and some other smaller electronics - tubes, cables etc.) without any hassles. Of-course the amp. was just $700 vs $3500 for the Marantz, but it appeared that customs was looking for gold, hidden in body orifices rather than larger electronic items in check-in baggage.Prices are quite lower in UAE too. I am going to Abu Dhabi next month but I really don't know if I should go through the hassle of getting one from there and if custom duties are levied, it might work around to the same pricing as in India.
Cheers,
Sid
