At first, I thought I didn't like the rolloff, but with my older Polk speakers, it made the highs less "sparkly" without losing any of the detail. I'm also not getting any kind of sibilance or harshness with dialogue even at blow-you-out-of-the-room levels.
I listen to a lot of music with heavy use of acoustic instruments. With stuff like Nickel Creek or Glen Phillips, I get a very pleasing and realistic sound from mandolin, guitar, etc. Even with violins, where I normally notice harshness in the highs, I'm getting a very solid sound without it breaking up.
Perhaps it just didn't mesh well with your particular speakers. With my humble RTi70/CSi40/RTi28/SVS 20-39CS+/Buttkicker setup, the 705 has been the audio equivalent of wiping a layer of dust off of a camera lens. YMMV.
Thank you for the thoughtful reply. Maybe Audyssey is useful after all?
Most users systems have so many other issues that this flaw is masked. More than usual power conditioning helped too. That is, don't use the high current amplifier conditioning outlets: use the receiver outlet.
I've been searching the various owners manuals (read not looking here) for receiver that can drive 4 ohm loads and drive an UNpowered subwoffer. A futile experience? Obviously this is where manufactures have been cutting corners. Limited drive capability. Wimpy amplifiers
But I can't put a stack of amplifiers in the kitchen now can I? So I'm still searching. My receiver price range is now up to over $1,000.
Update: The Yamaha 1800 can drive 4 ohm front only
"If the speakers are 6-ohm speakers, set “SPEAKER IMP.” to “6Ω MIN” before using this unit (see page 33). You can also use 4-ohm speakers as the front
speakers (see page 117)."
See how great of a bargain receivers are? Only $1200 to drive common speakers adequately.
Also here is a very important consideration for people who want to use their receiver with a PC based media server:
"Audio sampling frequencies higher than 48 kHz are sampled down to 48 kHz or lower and then sound field programs are applied
Here the Yamaha model 1800 sound fields can
be used with the PS3 and the Xbox 360 media servers which quietly transcode every audio source to 48K. Its degrading and unnecessary but true. (They sneakily are invoking DRM to make copying to CD more difficult. The consumer, as usual is clueless.) The question here is how many receivers sound fields work at 48Khz? Congratulation's go to Yamaha for realizing and developing a solution for this serious incompatibility issue.
