Is there any truth to this question?

Digepix.
When I posted above about my opinion and Defstathiou`s experience I did`nt know you had the larger Krell amp already.I guess I`ve been preaching to the choir.
Your conclusion is the same as his.Forget your well meaning friends and just trust what'you' hear. YBA must be very good equitment(I`ve never heard them).

This may be a silly ? but when the term "clipping" is used..Is it referring to the amp shutting down momentarily or the speakers making a clipping sound?

Here's another one: Harbeth speakers, less sensitive than my Vandersteens and are an easy load for amps to drive my YBA amp is a great match for them.

My Vandersteens are more efficient, easy load to drive but it's open to debate if 50 watts is enough.same room, near field listening, same average volume and type of music.

I'm confused

If the Harbeth's were similar in their frequency response and impedance characteristics to the M40.1, for which John Atkinson's measurements are shown here, there are a couple of factors which probably contributed to that.

First, their near-field frequency response has a 7 db peak at 70 Hz, relative to the response at 1 kHz, and a smaller but significant elevation throughout the mid-bass region. Those are the kinds of frequencies where most music has its greatest energy levels. A 7 db rise results in the same sound level at the particular frequency that would occur if there were no rise but amplifier power is multiplied five times.

Also, as JA notes, "the M40.1's plot of impedance magnitude and phase angle suggests that the Harbeth is easy to drive in terms of its demand for current."

I know of a fellow 'Gon member who very successfully drove an M40.1 with a 32 watt per channel VAC Renaissance 30/30.

If an amp is clipping, there is a good chance the sound quality is negatively affected well before any any clearly audible distortion is noticed. Better to have an amp that goes loud effortlessly to provide headroom before any clipping comes into play. One might be surprisec what is needed to do this for less efficient speakers. The difference can be subtle but very significant. With the exception of very efficient switching Class D amps, some weight and size is usually required.
