Thanks for posting that Joe. Generally a very good review of a modestly priced product. It offers most of what the M10 and M33 do, though perhaps at a slightly lower level than the M33. In particular the casework is pretty basic and the LED display is not a patch on the M series units. If bought with the new C298 power amp and a good pair of interconnects, there's still a small saving in cost compared with the M33, but I personally am happy having paid the £4000 cost of the even more excellent M33. For those with a decent power amp they don't want to change, the C658 is surely a crazy bargain at £1700 or the even better $1650 US price that presumably excludes tax. Peter
