Amplification for Wilson Audio Sasha on the cheap

Again, despite the low impedance at 80Hz or so, the speaker is easy to drive. We got walloping bass using our MA-1 amplifier which is an OTL, which are not known for driving low impedance loads.

So if you have 100 watts of good quality, tube or solid state, you'll be able to make this work, unless you have a large room. It is sensitive to speaker cables though, so you may have to audition them to find a combination that works.

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:

The Sasha is easy to drive and if you like tubes, most any 100 watt tube amp will do the job with plenty of bass despite the low impedance at 80Hz.
