I'd take the John Atkinson numbers from that review with a grain of salt as far as their delivering insight to what works well with the Sasha. The Wilson guys, as well as other reviewers, are apt to tell you 'listen first - then consider measurements'. For that matter, consider Dudley's comments based on listening with his Shindo gear. Room size and acoustics will also be factors.
Not that the test numbers are inaccurate for the test Atkinson did in the context he did it, however they don't tell us how the speakers sound or interact with different amplifiers. As far as I know Atkinson only uses a solid state amp for his measurements - does anyone recall his saying what is that amp?
Traditionally Atkinson has been somewhat er, uh, 'rigid' when it comes to matching amps and speakers. If you read past reviews of other Wilson speakers he tends to claim they require high power solid state amps to drive them. But, if you look at the amps Wilson chooses to show with, it has not been uncommon to find them paired with, for example, lower wattage Audio Research or Lamm tube gear. Also consider that Wilson speaker impedance plots will have dips in the upper frequencies - consider what happens there with solid state gear that increases voltage when impedance goes down.
I'm not suggesting that John Atkinson's opinion should be ignored - far from it and I'm glad we have his measurements - but my own experience along with reports from different reviewers and folks whose ears I trust have taught me the Sashas and other Wilson speakers can deliver very satisfying results when driven by amplifiers outside Atkinson's parameters. In the case of Sasha it probably is a good idea to pay attention to Wilson's minimum wattage suggestions.
I'll suggest dropping a line to Wilson customer service (which is excellent btw). They and their dealers do a lot of Sasha in-room setups and I'll bet they have direct experience with the amps you mention.
