About equipment, i change all my gear when tired of using some components i change them as i have a big hi-fi components colection , mainly from my father who passed away three years ago,
about hi-fi my main conclusions are ,
70´s material was the best made till today , and with adaptors it works with the more modern features,
like streaming and bluetooth or wi-fi but not as good as wire conected,
also big boxy speakers do make a huge diference in sound quality to prove it just take a look at all old edition speakers style released in the last years,
speakers on stands and directelly pointed to us and very close to the system maybe not the best way to have the perfect sound flow,
just noticed that after changing all this last month mainly when installing diferent speakers on my main sound room,
also , old cartridges when comparing them with new ones they are far from 70´s quality or even 90´s ,and the price is a lot excessive taking in consideration the inflation, the prices were expensive but not several times a midle class wage , `till a certain quality ,
like the 2Mblack from Ortofon , nice but price wise is stealing, bought it but yet to be a permanent cartridge on one turntable ,as i use S-shaped arms ,mainly.
The old fits better and sounds as good as or maybe better as some records sound very strange when played with new cartridges while older ones are compatible with all types of sound recording,
the first i bought was the Grado prestige III Gold, when released excelent frequency response but not that many hours of use, it feels that almost never used but i needed a substitution needle two monthes ago.
To finish i have three Ortofon cartridges , first from 1977 ,second from 1984 and the last in 96, they were expensive but the work for years and sound better than today´s many thousands of €´s with a short life.
In the past Orofon meaned, "Quality assured" now some are the worst i ever heard in my life like the 2Mred and a OM 5.
Only my opinion ,others might not agree with me.
