GMA Callisto feedback Green Mountain Audio


Anyone else breaking in a pair of these speakers? I have a pair with about 24 hours on them, and I hear moments of spectacular sound, but not yet at low listening levels. I know 200 hours is the magic break-in time period.

See my system under "Leahy" listed under "evolving system" for other system details.

Let me know if you would like updates as these break in...

I've had my Callistos for about 2 weeks now. They arrived with about 100 hours of burn in on them, and I've played them about 40 more since then. Right out of the box they sounded remarkable. Rhythmic, effortlessly tuneful, with engaging voicing on all instruments (voices, guitars, piano, as well as low-end instruments, cellos and bass guitars). Tonight I finally ran my low end test on them -- Beatles' "Come Together" on vinyl. This is incredible! I've got a smaller room (12 x 15) and these 6" woofers just filled it with Paul's cocksure bass lines. I'm not a tech-oriented person,so I have no measuring instruments -- I just know that I've listened to this song in many places, large and small, over many years (too many), on many systems, and it's never sounded this good. Real loud, with no break up, no strain, just pacing and pounding, and John's vocals clear and compelling. A couple of tracks later on Maxwell Silver Hammer I suddenly noticed these 2 acoustic guitars, quite treble-y, playing fast little chords, adding an angle I've never heard before and altering my understanding of the song, after all these years.

Besides great bass, incredible instrument voicing, and captivating pace, I have found one more surprising thing with the Callistos: at least 50% of the sibilance I've put up with for years is now gone. Just disappeared. I had been assuming that most of the sibilance I was hearing was inescapable, built into the source material -- WRONG! I'm listening to Norah Jones, to Indigo Girls, to Ella, Dakota Staton, and there's barely an ssssss to distract me. When I do hear it, it sounds natural, less annoying, and it's gone before I realize it.

It's funny, I've been meaning to post my initial impressions for the past 6 or 7 days, but whenever I have a chance to do so I decide to listen to music instead. The other side of Let it Be just finished in the next room. I'm goin' back for more....
I have the Europas too. I have about 600 hours on them and I agree they get better and better as time goes on. One more plus to the Europas is they actually make bad recordings come alive. A lot of speakers sound so dead and dull on bad recordings, not so with the Europas.
Damn it, I may have to upgrade! I agree that the Europa gets better and better as you go along. I have had them for a year and a half now (how many hours?) and I find day to day that I didn't hear that, or this is smoother etc. I have owned Maggies in the past and they were my other choice but due to room size I picked the Europas. I will say that I am amazed that these "box" speakers can have such an open spacious and lively sound.
Watch out guys. You don't want to get branded as "Hypers".
Winegasman, did you own the Europas before you bought the Callistos? If so do you think they are a lot better than the Europas? GMA thought they were something like 500% better than the Europas.
