Ah yes, a very good system. All great Arena Distributors product, except the Grace and Supex. Grace and Supex were naughty invader product from those east coast barbarians Interdyn
My first Linn had a G707 arm and SD900 cartridge. Here in sunny Perth every Alberts shop, (all owned by Arena) pushed the Linn/Accuphase/Gale combination. They ran the promo in 1975 of:-
Linn/SME/Forgotten the cartridge
Accuphase E202
Gale GS401S
All for $1975.
Joe Public had to work hard to be offered Naim ampliflication with Gales, even though it was also an Arena product. But not impossible as a lot of the sales staff ran Gales with Naim. Back then a behemoth Accuphase pre/power was more the normal upgrade path.
I first worked at Leonards, (another Arena owned shop), in 1977 and my boss turned me onto Naim. I had the same system as you briefly. Just a few weeks in fact as I zoomed my way through to active Isobariks.
Arena had the most amazing staff purchase scheme!
