As A Youngster, What Unit Puqued Your Interest In All This?

Sansui was great in audio in the S.Q. /price ratio scale...

Now i am on headphone only , and the Sansui alpha drive them very well...

but the AKG K340 is near the top of high end not the bottom in the headphone realm...

It is very sensible to the electrical noise floor of the house  and component...

then even if Sansui is more than great, i must think about a dedicated headphone amplifier if not out of the electrical grid as my dac , dead quiet,... more quiet than even the quiet Sansui...

I am on vthe fence to upgrade...

Even if the Sansui AU 7700 were extremely good so muck i never change it when i had speakers... So much more quiet than the 7700 the alpha is, a top headphone is so sensible to the electrical noise floor i must consider  an upgrade...

Probably the Berning microzotl...

I would had never change my Sansui with any speakers upgrade...So good they are...

But refined  headphone need dedicated amplification ... My headphone system now is moere resolving than my speakers/acoustic room... So different they are the K340 is my favorite...

Mahgister, I bought that 9900 used for $250 , enjoyed it for about 8 years and ended up giving it to my brother. Unfortunately it got stolen from his apartment

Wish I still had it 

I own a Sansui AU 7700 and a Sansui alpha 667i...

marvels at low cost no one can called obsolete amplifiers...

Did you always own the AU 9900 ?

My Dad had a Sansui BA and CA 2000 when I was young.    When I was 15 I took all of my paper route money and bought a really nice used Sansui AU9900.    

At 4 or 5 years old my father singing to me some ave maria stella, i remember it till today ...😊

The radio listening at noon of folklore and small traditional chorus music which gave me for the rest of my life the taste for choral music...i was 5=6=7 years old...

A cheap small radio working with battery in 1964... I used it in the evening beginning of night under my blanket instead of sleeping ... I even remember Paul Anka song and few others that strike me at first... I was 13 years old...

After that a Bach concerto in the music course...

After that a friend who owned a true stereo system with big  Tannoy ... classical music...I bought my first Tannoy pair... They last  more than 40 years before i sold them because of their size and my desire to go back smaller... It takes me 9 years to reach a good audiophile level after this move...

As all people around me  at 15 or 16 years old i was liking the Cream , the Beatles and the Papas and the Mammas, especially for me because of the blending voices, but i stayed mostly  in chorus music and Bach listening mainly ... Some french poet singers too till this day Leo Ferré and Georges Brassens with Bob Dylan and Joan Baez  and Cohen .........

My life changed when i discovered Bruckner at thirty and Scriabin at forty and Jazz after ...

All my life in one page....

The gear was important only for the music listening never the reverse... Now i am done with audio... I succeeded creating at very low cost a system with no apparent acoustic defects..... Under 1000 bucks it is very hard if you are difficult about sound quality as i am... It takes me hard work...
