Thanks for your reponses. Although I can audition the Halo's, doing so with the Statos is not an option. The one thing I don't want to give up is the nice warm Mosfet sound the Hafler has provided for many years. I also upgraded the 220 with 40Kuf caps a few years back, so the control that you refer to is even more evident with the VMPS's. Lots of watts is not really an issue to achieve fairly high SPL's because the speakers are quite efficient. 1 watt can produce 96dB @1 meter. Again, than for your input.
Halo or Odyssey
Opinions Please! Speakers are VMPS Super Tower/R's with newly updated drivers, driven via PS Audio 4.5 Preamp/Hafler DH-220 power amp. Considering an ugrade too new components without breaking the budget. I am wondering which would be a better solution, the Halo P3/A23 or the Odyssey Tempest/Stratus? Or should I just keep the PS and Hafler until they expire? The sound they produce is still quite satisfying. Thanks for your time and help.
