Amplification for Wilson Audio Sasha on the cheap

you'll need an amp with current,

What is meant by that? Enough current to drive the speaker? Or something else?

We had no trouble getting excellent bass on the Sashas using our MA-1, which may or may not be a 'high current' amplifier, depending on what is meant.

'High current' tends to often be a bit misleading- see this article for more information:

 If I had a current hungry speaker and wanted to get decent results without remortgaging the house I would get a Sunfire load invariant amp.  I have never owned any Wilson's though and probably never will. I typically wouldn't go for speakers that are tough to drive unless they were panels  for the exact reason that I couldn't use the amplifiers that I would want to. 

Agree with atmasphere. Have heard Sasha's with ARC Tube Amps and they sounded very nice indeed.

Like I said before:
  "Sure a tube will work and mostly sound good, but the best will not be extracted from the Sasha's in the bass."

@kunilraiker     An ME850  will drive your Sashas, but IME there are Amplifiers that will sound much better.
