Yamamoto HSA-01 headshell/head amp

@stereo5 : I think that the Ortofon SPU models were the first integrated cartridge that appeared in the market and that in the latest times we can buy in stand alone version ( some models. ) too.

Through the years other cartridge manufacturers did it the same and in no one of theirs cartridges came with head-amp integrated. Some of those manufacturers were/are ( as Ortofon some models came too in stand alone version and even in plug-in version. ):

EMT,Audio Technica, Fidelity Research, Sonovox, Glanz, Goldbug, Sony, Ikeda, Signet, Grace, Audio Note,Yamaha, Technics, Thorens, Acutex, Dynavector, Azden, ADC, Shure, Nagatron, etc,etc.

If we are willing to do the Audio World gives us the opportunity that every day be a learning day for any of us.

Dear @stereo5  : Obviously with all respect.You arrived to Agon in 2008 and you have 6,283 posts that are a lot and that could means you were/are participating in hundreds of threads in the forum.

So, it is weird that from all those years you never had the opportunity to read any of the over 850 SPU references/posts in Agon.

Nothing wrong with that,only that the SPU cartridges are perhaps the most famous Ortofon cartridge models.

Never mind, it's just that I was thinking " loud " in that issue. Sorry.

Dear @lewm : You are rigth today op-amps are way better that the ones in the 80’s.

I’m with you that bougth it more by " curiosity ".

" will be a revelation ". I think not because it has very limited frequency range ( I can’t understand why is that but was what Yamamoto choosed. ) and you don’t know its levelnoise that I magine should be low but we don’t know.

Normally headamps has a frequency range from 0.5hz to over 500khz and some -3db at 1Mhz, this is another history and not a " open door " for this thread.

Yes, share with us what you experienced with.

Dear @lewm  : That's not a new idea, many years ago appeared in the market but with no true success. Rigth now I can't remember the manufacturer but if I remember ( ? ? ? ?  ? it came together with the cartridge. ( Can't be sure. )

Regards and enjoy the MUSIC NOT DISTORTIONS,
