This amplifier sounds phenomenal.
It is also built like a tank.

I compared this vintage amplifier to Nakamichi 730 and Akai just plain sounded better and sweeter despite having lower rated power; a keeper.
Nakamichi 730 used to be top Nakamichi model in late 1970's.



re: AM-2400

This is a beautiful sounding amplifier and well worth buying if you find one.
Rated at 40wpc which is just the minimum it would be more like 50wpc or more.
Akai rated there amps low which leaves headroom should you need more power.
You buy these old amps for there sound quality but they still have plenty of power.
Akai's higher end model's are collector items these days and are going up in value.
This amp is very full sounding with good solid bass.
I am very glad I brought mine.
This was my first Akai purchase which started my collection ... enough said.

re: AM-2400

Thanks for you post this is actually my 1st amp vintage purchase.
I am glad to read your comment and can't wait to set it up.
Ha had to choose from a marantz 2225 - sansui 681 and this AKai Amp + the tuner.
