Can anyone advise regarding this ?
Here is the reason why there will be such a dichotomy: http://en.wikipedia.org/wiki/Dunning...3Kruger_effect
The folks with Dunning-Kruger/zero technical literacy will not be able to discern between their imagination and reality....and they can't be cognizant of this situation/shortcoming (a closed loop scenario described by the wiki link above).
You have a choice. You either accept that there are psychogenic "improvements" to the "sound" that are produced by an amplifier namebrand, price and audiophile "street cred"...which will affect your mind in the same way it did audiophile X...and therefore "sound" "better", etc.
...or you believe that the function of such a component (voltage amplifier) is to increase the signal level and contribute no "sound" of its own (real or imaginary).
The only time you will "hear" an amplifier, is if it is poorly designed (like many "audiophile" designs), or driven past it's linear limits...which is exactly what will happen with some of the lower power, but "audiophile" brandname designs.
The key to a "soundless" amplifier, is good low level (<1w) linearity (Gedlee metrics is an excellent test...and known by the "Pro's") and sufficient dynamic headroom, to offset the onset of clipping, at levels above your loudspeakers compression thresholds (not that high for your average cone 'n dome box tragedy). The higher power "pro" (and "home") amps will drive your loudspeakers to quite audible compression and distortion (audible, really real world...no audiophile imagination required) before the onset of (severe) waveform clipping.
Hence my 150w+ recommendations (with sufficient power supply rails/high power reserves and low impedance drive capability) - no psychogenic criteria required to "hear" such benefits (or visual clues, or priori knowledge, etc.).
