Building the Audio Note Kit 1 SET amp...

Always avoid clipping even if subtle.

How hard it will be to find new speakers and how much will largely depend on how much bass extension is needed. If not full range it won't be hard or expensive.

Rebbi- if you think that your amp clips "a little" you might want to consider a sub or pair of subs with its own amplification. I know the ref 3s roll off but I'm not knowledgeable enough to know whether that affects the amp trying to amplify those low frequencies which really gobble up the power.

i'd be willing to bet a sub or two would resolve the problem.

Not only resolve it but allow the set to do what it does best even better . Offload the power hungry lowest octave or so and you can have it all for reasonable cost. It's a no brainet for me to eliminate the problem and grt the most out of what he has

I wasn't aware of the thread where he stated the amp clips on certain music but I'm not at all suprised. I would have been quite surprised if this wasn't the case. 8 watts is just not enough power for those speakers on dynamic full range music regardless of what any of the manufacturers may have inferred to him at the outset.
