Honestly, i have never dealt with him so i can't say much about him but haven't rally heard bad things about him.
The prices quoted by him are very very fishy.I double checked the prices with the Hermit Audio who is dealing in these products and then posted the MRP above.
I have no clue whatsoever why is he quoting so low but if he is ready to sell teh stuff which is box packed, with warranty cards etc. i would think, whats the harm in getting them ?
