I recently auditioned a pair of Castle Warwick bookshelf speakers with a Cambridge Audio Azur 851C and a McIntosh MA252. I was interested in it as a less-expensive compromise to approach the Harbeth design philosophy. They sounded very warm and natural in the shop, then harsh and brittle through Cambridge Audio Topaz AM-10 in my small room at home. I have found a sound I like, but it seems to be very hard to reproduce at home, and I am stumped. Can anyone offer any thoughts? I would be very grateful for suggestions for speaker/equipment combos I could try, as well. Thanks in advance-- this is one of the few sites I have found where I feel I can have confidence in the information provided!
