from your experience, you have already established a good buyer-seller relationship with eric lim base on your transaction history, thats very good.
my only concern is the price, acoustic dimension was the former distributor of Cambridge Audio when they were still located along Araneta ave. I rememberd inquiring an amplifier and cd player back in mid-2007, their price ranges from 21k-37k for models 340-640. I was not impress with the performance-price ratio, so I did not buy it. Sometime in October, a friend of mine who pesonnaly knows the owner of 5th Ave gave me a pricelist of the Cambridge Audio line as they are now the new distributor of this brand. The prices from 5th ave reached up to 15k lesser than acoustic dimension , it settled down to the price of NAD in the market.
From the price you have, it is in the level of Rotel.I hope it has the same sound and built quality as Rotel.
If you will be patient enough, baka bumaba pa yan. look into its technical data sheet, and make a comparison with NAD,Cambridge and Rotel and see where it would be more comparable.
