Their sensitivity (actual in-room response) is around 87.5db or so. But their actual minimum impedance is just below 4ohms between 80 and 100hz (about 3.7ohms). Not the best match in my book.Īnd the Denon 3808ci with it's reserved (laid back) and kind of bland sound, is also not a good match for your Mirages.īy the way, your speakers are rated at a nominal impedance of 6ohms. I believe that the Pioneer with a class D amp (ICE) is robbing you from the details and liveness of your Mirages. I guess you didn't try bi-amping them by the way (OM-9)? They need special attention, as the right amplifier or receiver. Here's my theory: Your Mirage speakers (OM-9 and OM-C2) are Omnipolar and quite unique. Ok, Pure Direct doesn't cut it compare to your older HK. Would a new H/K AVR with HDMI be a better choice or Yamaha or is this a HDMI audio issue? I am stumped? But I really wanted a HDMI switching receiver, with more power. I need help, I don't understand what happened? I am going to return the SC-05. I re-connected my H/K520 via optical/component and my Mirage OM-9's and center Om-C2 came alive at higher volumes and very clear detail. I thought the sound processing via HDMI, + the added 55w & THX would sound better. All were connected via blue jeans HDMI cables. No punch! I tried movies via my cox cable and dvd's & BD's through my PS3. The SC05 had to be played at +05db's to sound just ok, but lacked any real detail. I had even tried a Denon 3808CI via HDMI with same results. I was hoping to gain more sound detail & volume. I replaced my 5 yr old H/K AVR520,75w, with a Pioneer Sc-05, to get HDMI switching, + SC05 is rated at 130w versus H/K 75w.
