How good are new arcam amps against the alpha 9 and 10. I noticed the price of arcam products have gone up by large amounts since new ranges have been added. I consider the alpha 9 amp very good and I am wondering whether the new products are worth the money, what improvements you get for all the extra cash. I am looking at getting another p9 amp for my home cinema set up to bi-amp my front speakers when using stereo to play music. How good are the fmj range and the 33 range. I have seen I can get an ex-demo p7 for £1700 and want to know is worth spending that amount of money over buying another alpha p9 for a couple hundred pounds.
