Amplifiers from the big [expensive] brands in Japan?

Hi all,

I’m a new member on audiogon!

My question is regarding amplifiers. But first, a bit of backstory so you guys have an understanding of my current audiophile situation.

I have owned vintage gear from brands like Technics, Pioneer, Sony, AKAI, etc. I’m talking about amplifiers, CD players, etc. and they all sounded pretty good.

Currently I have a pair of headphones and a dongle for my Android smartphone. Looking to build a system one day. Got to save up money for it.

I’m looking into the following brands as the ultimate end game.

Accuphase, Esoteric, TEAC (higher-end line up), and Luxman.

There is an audio store pretty close to where I live and they carry some of these brands. The owner said that she could set up an audition for me with different speakers - and I even get to use my headphones on the 6.3mm out of the integrated amplifiers.

My question is - are these very expensive audio components able to bring you closer to the original sound? is that the reason for their high prices?

For any owners of audio gear from these brands, please tell me your impressions about sound quality, build, parts, etc. Since they are all high-end brands, is the sound quality similar or very different between them? For example, is there a "signature" sound that only an Accuphase can have?

I’m here to learn and I appreciate all the help I can get.

My best,

Jack.
