Depends on what you buy. With selectively bought 80’s 90’s top of the line you’ll still pound most of what’s offered today. Restore, upgrade where possible and enjoy what most still can’t afford. It’s all mechanical and all eventually needs work, that said most can still be done. Look inside the average ‘quality amp’ today what you see is the cheapest possible parts and assembly line work, otherwise that $6th unit would be $12th, and so on. Then there’s the specs and hearing, odds are you won’t go wrong there either. The market is there to get you to buy, Great still beats good modern or not.
