Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker

@douglas_schroeder    When I refer to "level unlimited" I mean that the amp is at maximum output of the preamplifier turned full on and the speakers not hitting past perhaps 87-88 dB. I would call an amp "level unlimited" where in my use I would not turn the level up more, but the amp could certainly provide a higher listening level. It may not be a technically correct description, but it serves to indicate the situation. I do not attempt to listen to systems at "live", i.e. above 90 dB levels, and I do not recommend others to do so

It appears you may be confusing gain with power as many do.

This is the statement I do not understand. The amp is doing what?

The top setting on a preamp does not conform to any percentage of the power amplifier's potential output. Some systems max out on power at 9 on the clock. some at 12 some not even at full up, which is a good situation where the 9 on the clock is very bad, though I hear some like it as they think there headroom above that setting, where there is not. 

90 db is a nice listening level, however do you sometimes find a CD might not get to 90 at full preamp level? And of course some will be too loud.

He is, by me too.

The amp is FAR superior sounding in bridged mode regardless of the speakers used, efficient or less efficient.

I ask again, then why sell it in stereo mode if it’s so hobbled in stereo mode???
You should then be suggesting that no one buy it for stereo mode listening there are far better offerings.

I have said several times previously that there is NO sonic degradation in bridged mode, nor distortion associated with running the amp full out.

This is a furphy, I didn’t ask that half a page back, I asked a simple question of amp sound quality driving the Kingsound III it was ignored. I present it again.

"How did one stereo amp sound to a level it was totally comfortable at.
Then the bridged ones at the same level?"
"To gauge which sounded better."
"NOT WHICH COULD GO LOUDER!"

I think it all needs "paralleled interconnects attached to each channel", that should fix the problem/s.

I think Benchmark has done an excellent job of convincing everyone to buy two. Hail to marketing. All those who follow can do is quote the party line. We will never get them to understand.

Got a feeling there’s a couple of latent shills helping out too.

Likely indeed. The marketing guy did step in at one point. We really gave it a good shot.

Check out this thread claiming there is no RMS power.

 Read the banner at the top of the Wicki page and check out the references given below. especially #8. Then read all the compliants on the talk page. Im writing someting up.

to me

From Wikipedia "Audio Power"

As described above, the term average power refers to the average value of the instantaneous power waveform over time. As this is typically derived from the root mean square (RMS) of the sine wave voltage,[6] it is often referred to as "RMS power" or "watts RMS", but this is incorrect: it is not the RMS value of the power waveform (which would be a larger, but meaningless, number).[7][8][9][10] (The erroneous term "watts RMS" is actually used in CE regulations.[11]) This is also referred to as the nominal value, there being a regulatory requirement to use it.

Al, leave it (he is not going to get it). .
