The more a brand has been sold, the more you'll see them ?
But Sony and Denon Pioneer have/had sv manuals leaked or made available easier than other brands ??
In my youth, i've seen more Sony been repaired than other brand, we could get parts for very old sound/video systems of modules / component systems in the 15 years of age some parts where still available.
Now no companies hold parts for long, you buy and trash things more often, now its consuming times and practices i hate the most.
I have an old 80-82 Sony TC-K71 casette deck, and a huge cassette collection ( high end casettes ) this deck is incredible, redone completly the psu, the noise floor has dropped radically, i'm converting them to MP3 at 320 kbs, no companies have beaten this model
The Sony Esprit series at the time was an excellent pick.
The Yamaha high end sound systems where hard to beat, the dsp a1000 a the time was a reference.
Onkyo : where okay but so so ... may have changed
Marantz : saw many equipment over rated at the time, an supposed Hi-fi high end model was not as advertised, was an class A-B amplifier, and was sold as Class A .... was on the shelf a very long time

Mitsubishi : in their vcr was very deceptive, their high end SVHS did not had parts available after an year IE: U80 U82
Pioneer : where good in the high end stuff, not for the normal customer, seen high end full copper casing models (can't recall the serie) beaten by a mere 200$ Sony cd player, a fist bang on the bench, the sony played perfectly, and the Pioneer skipped, saw many angry clients at the time for theses players.
Sansui : saw tons of sh@#$ but some big / high power amplifiers where incredible, and build like a tank.
Hitachi : they had made some really good tv's at the time, saw and repaired tons of vcrs (the clutch kit) did not last long.
I repaired lots of brand in the past, now if i have to choose i would go for some of the older brand and models ...
But the choice factor would be : is there an SV manuals available for them, if not eh i dont by them
The biggest problem for me : is the obsolescence of many electronic equipment, nothing last long, i had stuff who lasted 15-20 years without repairs.
Now 5 years after purchase you dump them
In Canada that's what i saw or did, in other countries or continent(s), other brand(s) where more popular.
most popular
Sony, Hitachi, Pioneer, Mitsubishi, Sanyo, Samsung, Technics (mostly the turn tables)
less popular
Realistic --- many where made by Sanyo
Jutan International Limitted --- oh boy (JIL) total crap
Carver
Onkyo
Marantz
Koss --- they did make very good shelf speakers that i have after 20 years, and made some incredible walkman
Bang and Olufsen
Zenith
My 2 cents
