He is also a speaker designer in his own right and was developing some products very similar to my Microphase around the same time, hence probably why he accepted to build our products.
As proof, you will find below some extracts of his catalogues, some products being sold under the GUY.HF brand and some more elaborate ones under the "Natural Sound" brand.
One skill that GUY.HF had and still has is the quality of their varnishes, perfectly applied and never too glossy in the case of the clear finish. Lacquer was subcontracted to a local company Segaud, which was later bought over and integrated into the larger premises acquired in 2003.
If you have ever seen a Focal Grande Utopia in the flesh, then you will have experienced both the cabinet making and the lacquer expertise of Jean-Paul's team!
I will be forever grateful to have been associated with GUY.HF and still counting Jean-Paul as one of my long standing friends. Stay tuned for more French Vintage Speakers!
