I wouldn't worry about Nelson Pass' designs getting dated too soon. Lots of folks (like me) prefer the Aleph sound to the X, for example. The newest XA series is meant to combine both sets of attributes, but at $$$$ pricepoints!
Which amplifier would you buy?
Does anyone have any thoughts as to which amplifier they would recommend? I am using a Krell HTS preamp with Revel F-30 loudspeakers, and enjoy music sometimes, but am more interested in home theater performance. I have narrowed it down to the Proceed Amp-5 and the Pass labs X-5. Both cost about the same and have about the same power output. Could anyone advise please. Thanks, Jeff
