I know both of those and rather liked the cheeky Townhend amps. they weren't as "pretty" as the Meridian 100 series though and didn't get the rave reviews that the Meridian 105's got.
The Myst amps were better than the CB Naims we compared them to in terms of image depth and overall clarity, but the limitations of the mid eighties Fruitbox and distortion quirks in the design (IIRC), coupled with the blinkered views of the "better" dealers, most having been absorbed into the Linn/Naim brotherhood, saw the premature end of this maker I think...
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
