Halo or Odyssey

I've only heard the Halo's briefly in a store, so I can't comment. I did do an extended side by side comparison of the Odyssey Stratos(cap upgrade) vs. my trusty old Hafler DH200 in my system. Frankly, the Hafler bettered it. No real differences at normal volumes, but when pushed the Odyssey let the woofers break free whereas the Hafler kept complete control. I think there are better options than the Odyssey especially if you like to listen at loud SPL's. They're not bad, though.

BTW, I was using B&W speakers/B&K pre-amp at the time.

I replaced a Haffler 220 amp with a Stratos in a friend's system (McIntosh 2200 preamp, B&W Matrix 805 speakers). The difference was remarkable - more detail, more control, more solid bass, better imaging. I guess my experience was different from Hammergjh's.

Peter was using a better pre-amp than me. I'm not familiar w/ the Matrix 805's. I was using the B&W CDM9 speakers. That might explain the differences.
