Which pair of speakers changed your Hifi life?

Snell A -II’s in the early 80’s for their deep, tight bass & full sound like few others back then. My brother’s Proac EBS’s around the same time for their great midrange  & 3 dimensional imaging w/ Conrad Johnson tubes. Finally, my Volti Audio Rivals now for truly live sound that bests most concerts I’ve been to other than the Boston Symphony in Symphony Hall. 

I have loved speaker every since my father helped me up grade my sunperman turn table by adding an extra speaker to it when I was about 6. The first was a pair of EPI that my uncle gave to me. This was the mix 80’s. I had to replace the woofers because of dry route. But they sounded incredible. They were warm with solid bass. I didn’t know what I had.  The other that changed me were a pair of energy speakers a friend had. This was back in 1991. It was a small pair of satellites hooked up to a small integrated amp. No sub. They did not do everything, but what they did do they did well. They imaged like nothing I had heard before.  I had a pair of self made speakers at the time ( I had been and still like to build speakers). They sent me on a quest to build or buy a different type of speaker. Before I focus on speakers that did everything but not necessarily right. To one’s that did what they could right. They also was the state of me learning about real hiring. What proper placement and setup could do for an ok pair of speakers. Also rom treatment, etc. I think I have come full circle and realize that there is not a perfect speaker. So I kinder love them all differently. I’m trying to break the habit.

For me, it was on a visit to my local audio store that I first heard a pair of ADS L810 speakers back in the 1980's. The music was clear and precise, with a sound I hadn't heard before. I took them home, tried them out and have been a big ADS fan ever since! I currently own their L1590/2 speakers and am satisfied that this will be my forever speaker!

+1 on the Kef 105’s. Way back in the late 70’s. I worked in a hi fi store to pay for college expenses. One of the guys hooked up a new pair of 105’s, sat me down and said listen to this. He put on “the firebird “ by Stravinsky and wow!!! These speaker’s were the only ones that gave me goosebumps listening to them. Since then I’ve been chasing the rainbow to get the same reaction from a pair of speakers. 
 I have had the privilege of being able to buy a few goodies over the years such as acoustat 1100, Martin Logan (various models), and a few other weird and esoteric brands. Fast forward to earlier this year, looking on Facebook marketplace, lo and behold. A pair of Kef 105/2 for sale at a steal price. Called and talked with the owner and found out he hated them! Didn’t sound like his Maggie’s ( duh). Set up a meet in a parking lot of a hardware store. Driving up I was amazed at the condition of the cabnets, like new. He had both types of dust covers( no rips or tears). Needless to say I kept my mouth shut, paid the man, loaded them up, and home I went. Full well knowing my wife would give me a hard time for buying another pair of speakers. (Side note , I had just bought a pair of Martin Logan’s). Well I deflected all the evil eyed looks, hooked the 105’s and the ml’s up and did a demo for her, not knowing what to expect. After listening to dido, the planets, tony Bennett, and Beethoven’s 5th. Her reaction was priceless. She said, the kefs were amazing!!! Now I have them set up as the speaker of choice for moment. 
  My home is currently under renovation, boxes, furniture, and stuff everywhere. When finished I’m going to hook up all my old guard speakers and do a fair comparison. I know most of you have mega systems that put mine to shame. I should say that this forum has helped me with several questions and thoughts. Thanks for the advice. 
  For now, I’ll sit back and explore my new node streamer and listen to the Kef 105/2. 

Dahlquist DQ-10s and Magnepans opened up my ears to what was possible for the first time in the late 70s. (Enjoyed ML SL3s for 16 years.)

The Raidho D2s by Mike Borresen took my listening to another level, revealing musical information on CDs I'd owned 20 years and that my Dynaudio Sapphires could not pull out. (Of course hearing mega-buck world class systems at shows is a hoot as well.)
