Benchmark AHB2 Amplifier, opinions and competition

As I’ve been listening to the amp and experimenting, the richest sound I get is with the sensitivity switch in the uppermost position with the highest gain.
The technician at Benchmark suggested the middle position, but on my set the upper position sounds best.

Try the Job 225. Lots of info and reviews online.

mzkmxcv, …."Even 25W is good enough for most setups (if you’re speakers are 84dB sensitive and you sit 20ft away, that’s a different story)."

This has not been my experience, my speakers are rated at 89db, 6 ohm nominal, although I suspect they are a little less efficient than this would indicate.  They only really came alive after I started using a 100 watt+ per side amp.  Oh they played using 35W tube and 50 watt SS, but they sang with the greater power.

Go to the cable forum and read up on the thread that bears my name, regarding the Schroeder Method of IC placement. I have been doing this with the Benchmark Amps in Mono and they are nothing short of stunning. 

@jetter

They might have stated in-room sensitivty (Klipsch almost always does this for instance, but they are even worse and use corner (2-wall) loading, so +6dB).

Bass-limited speakers usually get +2dB while almost full-range speakers get +3dB.

So, if they stated 89dB, it might be 87dB in actuality, or even 83dB if it were a Klipsch speaker.

Also, that’s at 6ohm, which takes in 1.335x the wattage, so my stated 25W which was for 8ohm nominal is thus >33W, not to mention if their minimum impedance take up a large bandwidth.

100W (8ohm) is +3dB vs 50W (8ohm);

It’s a good difference in volume.

You also don’t know if it’s just a better amp in general and that’s also why it sounds better to you.
