Amplification for Wilson Audio Sasha on the cheap

I currently have a ME850 amp

I own 2 of these amps active bi-amped, and I can say one will drive the Sasha’s without even yawning.
If you need to sweeten it a little get a tech to bias it up a little more from 8w Class-A to around 12-15w, fan are speed controlled according to heatsink temperature, but this is still dead quiet unless you put your ear up to the intake vents.

Thanks George, I need to get it serviced at some stage and might look at the bias adjustment then.

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.

I have heard the same too, so a decent tube amp can keep the bass right and get the low freq?

Stereophile bench test:
" On the other hand, the Sasha's plot of impedance magnitude and electrical phase (fig.1) reveals the speaker to be a demanding load for the partnering amplifier to drive. Not only does the impedance drop below 4 ohms for most of the lower midrange and upper bass, with a minimum value of 2 ohms at 86Hz, but there is also an amplifier-unfriendly combination of 3 ohms and –43° phase angle at 61Hz."

Lower bass if you want it kunalraiker clean, tight, rhythmic and punchy, you'll need an amp with current, sure a tube will work and mostly sound good, but the best will not be extracted from the Sasha's in the bass.
That 3ohms with -43 degrees of phase angle will look like 2ohms to the amp that's driving them.
