Over the years, I've had a fair amount of their kit pass through my hands. Any old MF kit I've sold has been almost exclusively sold to Far Eastern dealers who seem to fill whole containers with the stuff to send back, which probably explains why there is less MF kit around second-hand than its sales would suggest.
The best quality I think (fit and finish as well as sound for the money) was the E100/500/600 kit I had for about ten years from the mid-90s. I think I had only one capacitor fail in the amp that time.
A bit agricultural in finish but my biggest regret in parting (after the fact) was the Digilog DAC. Not the final word but respectable evidence that some of the earlier DACs were more euphonic than allegedly better later versions.
I can't recall the model number, but wasn't there a rather good small speaker in the late 80s/early 90s? Although IIRC there quite a few Far Eastern knock offs about, so extra care has to be taken to ensure that you are buying genuine MF kit.
I think the V series was reasonably good VFM, too.
The less good already adequately covered above.
