GMA Callisto

I know an Agon member that owns both the Sixpacks and a Berning amp, he may be a little more help than I. E-mail me if you wish. I have zero experience with the Berning, it certainly has a good following here, I'm sure it's a worthy candidate as well. Regarding "getting distracted" it's always good to go for a home demo, or buy used and re-sell if not what you expected. There is a ton of equipment out there, the possibilities are endless. True peace of mind lies with home demos that you hear for yourself.

I use a Cary Rocket 88R and Cary SLP50A with oil cap upgrade. All tubes have been replaced to nos of my liking and I have not turned back. The Callisto speakers still amaze me after a full year. I listen almost every day now and buy more and more music. Best audio purchase I have made in 30 years. Green Mountain Audio is a special place and I still communicate with Janet and Roy. Any questions, feel free to email me. I am a huge fan.

I have not heard the Berning ZH270, but I do know the Callisto's will show the quality of the equipment connected to them. Enjoy!

Well after reading numerous posts on AA(maybe a bad thing) I do now have some questions. What now has me worrried is how they sound if I'm not in the sweet spot, which it seems for these speakers is small.

Short of demoing these in my own inviroment can anyhere comment on how the sound differs from say sitting down to standing up all at the listening position.

2. How expansive is the soundstage
3. How does it differ say walking around.

Those are my biggest fears as my quests would never experience what I do.

Cheers

I don't know what was on AA, but the sound stage is huge and fills my whole house. I can sit to the side and still enjoy these speakers. The sweet spot is everywhere, not just one location like planer speakers, ect. Yes, there is one perfect spot, but it is not very noticable and took some work to actually locate it. The set up has a tilt to tip the speaker forward or back slightly and the difference is so small, it takes time to find it. I sit, lay down, sit somewhere else, or walk around and I always enjoy the Callisto. You really need to hear these. I enjoy the Callisto so much, I upgraded my equipment also. There is no set sweet spot that if you leave that spot you will not enjoy them. That is the beauty of the dual bottom ports. Music is everywhere and not really directional IMO. I wonder if the posts were meant to damage GMA since the posts could not be more wrong.
Give Roy a call at GMA and he will give you the technical on the Callisto. Also, send me an email and I can send you pdf. files of documents on the Callisto that Janet Lynn, the CEO of GMA sent me recently. Lots of information in these.

Elsneb,

Thank you for taking the time to answer my questions and to offer up information.

Cheers
