IF you don't have a stack of money in a briefcase for expensive gear,
there is another alternative. Like climbing a staircase one step at a time, you gradually upgrade over a period of time (in my case over 20 years) and pay in small increments while trading in what you already have. Waiting for the right deals to come along is fairly easy- you can
usually find at least one component becoming available every year or two that you feel delivers very refined sound but, in the case of an amplifier for example, has a scratch on the back where the speaker wires go. Used wire is fairly inexpensive also, and so on..
BUT, prices have become totally unreal. My 1st really great amp cost about $5K and THAT was crazy enough (as everyone i knew kept repeating to me). But it really made a big difference in the sound coming out of my speakers. So i was really happy about my decision, and for several years afterwards. Now i am on my 5th amplifier,
but i kept learning more and more as the years went by. But YES,
there is definitely a limit to what anyone would need in what most
people call home. OTOH, If you are wealthy and have a LARGE DEDICATED
SOUND ROOM, then you don't need a magazine to tell you what to get- you fly to New York, visit all of the audio salons by appointment,
and choose whatever you want.
Or you buy the equipment with the most impressive appearance
and/or matches your decor.
