Perspex was a suggestion that occurred to a number of end-users simultaneously. It isnt dogma. It was a suggestion. Nothing more than that.
If glass could be bent into the appropriate shape at a reasonable price then no doubt the end-users would have gone for that. You dont like Perspex? Well fine. The point is though that microphony is not an imagined event. However it is certainly true that not everyone can hear the effect. Its a question of choice as to what to do about it.
Mind you, to ability to hear the effect is somewhat dependent on the process involved. If for example you take a unit (not necessarily LFD) and play it in the system with its resonant top case attached, and then at the identical volume without the case attached, a slight difference may be perceived. Fair enough.
However in my experience, listeners are more likely to hear the effect when the process is reversed. By this I mean the system is played without the case and then with the case. The latter is more time consuming though.
In each instance, for the effect to be heard, the case must be screwed tight to the chassis. No easy matter with LFD as the deliberately soft-head Allen screws used are not happy about being removed and replaced frequently. Frankly, I do not advise it.
For those that can hear it, and dont like it, a solution to microphony is desirable. Battleship-type construction is one approach, applying semi-inert sticky panels is another and safety issues not withstanding, removing a top cover (most certainly not endorsed by me as a retailer nor LFD as the maker) is another. Thats the reality. The end-user has a choice. Unlike a number of other UK audiophile makers, LFD recognise that their end-users are adults and, in the main, readily able to think for themselves. Over here in the UK, thats an approach which is as refreshing as it is rare.
