yes, and the class D amps in 2 & 5 channels are quite capable
"Two channels driven continuously into 8-ohm loads:
0.1% distortion at 144.5 watts
1% distortion at 191.6 watts"
if they can drive 4 ohm 85 dB efficient Magnepans even without a sub, then they can drive his 92 dB efficient, 8 ohm KEF's with woofers
no, I would almost guarantee it's not
the amp. not even close, although I wouldn't argue that more power can't make a speaker come more alive because that is definitely the case with Magnepans, which are notorious for wanting hi power, hi current to sound their best..
Severe deficiency in bass will not be resolved by changing to a comparable powered receiver. the Pioneer SC's have been shown time and time again to hold their power even with multiple channels driven to same level at same time, when others, like the highly praised flagship Denon 4520 has been tested by one German review site and they got sags to about 60 watts IIRC when 5 ch driven simultaneously.
his problem is most likely defective speakers, poor room layout-bass suckouts, or his expectations
he already has a next action step to do: manual EQ boosts (suggested days ago by several, including me)
so let's not confuse the issue by telling him he needs to change receivers already
that would be the very last
thing I'd be trying.
why the continued discussing & debating instead of him trying the next logical steps? including just trying another speaker in the room, which has been suggested by several already.
If it were me, I'd be 1)make 100% my setup was correct 2) try manually boosting the bass region in the EQ'r and 3) try moving the speakers or my listening position. If all 3 fail to make me happy, I know what I'd be doing - and it wouldn't be to continually discuss this on a forum OR sell my receiver
I'd be sending-taking them right back to the dealer and start demo-ing other & better
speakers, seeing if my dealer would allow an in-home evaluation.
if I don't like the way my speakers sounded, I'd get different speakers. selling my receiver at a loss, getting another one to try or doing bi-amping to compensate for some unknown deficiency in the hopes it may make a difference would probably be a waste of money & time.
in audio, the speakers & the room are 80-90% of our sound quality, the electronics a distant 3rd place. if the amp is powerful enough to drive them without clipping, then swapping amps isn't the answer to sound quality, imaging, soundstage, depth, or in-room freq response. his speakers are spec'd for 50-200 watts so 140 watts is plenty
