Bi-amping - impact?

Biamping and Naim don't usually go together, though some have used the SuperUniti and a NAP250.2 to good effect. The only way is to try it. All Naim amps have the same gain, so you can mix and match without worrying about different power ratings. You can either borrow cables from your dealer or buy some used and sell them if it doesn't work out. I can't help thinking that a SuperUniti would be a better solution on the basis that one big one will usually beat two little ones.

Biamping can work. I successfully biamped with two 300s until I went passive with the 500. As HH says just try it if you feel inclined to do so. It will either work for you or not.

I would not bi-amp SMC11's with the amps you have, with all due respect to your amps, they are not power houses & your SCM11 needs power.   

And no,   30w + 50w does not = 80w with bi-amping

I assume your thoughts on bi-amping was to have the Qute 30w to the tweeters & NAP100 50w on the bass.  

The HF section tends to be an easier - but not always - load. 

The bass load especially in the low-mid area below 200Hz (aprx) is normally the most difficult consisting of reactive elements (back feeding EMF), phase angle changes coupled to rising & falling impedance & with the lowest ohms of the whole audio range.

I've looked at the measurements Stereophile have & it looks to me that the SCM11 is not an easy load.  I would expect it works at its best with an amp with more power than your NAP100.

It needs an amp with the ability to deliver volts & amps against a low ohm & reactive load & something like a NAP250 is probably a better match.

Tried it with a SU and a 250.2… wasn't my cup of tea.

Ok, tried it. NAP100 powering woofers and Qute on tweeters.

Some music sounded slightly better with bi-amping, especially spartan, bassy tracks like James Blake or all-out thrash like Royal Blood. The bass went deeper and stronger. But unfortunately most music also sounded darker and slightly veiled to me. I felt i was missing some liveliness. Close vocal tracks like Laura Marling sounded oppressive, and open, airy music like Goldfrapp sounded more closed. I found myself admiring the bass but missing some joy in the music.

I spent a day or so with it, and played a lot of albums, and overall it was an easy decision to go back to just the NAP100.

How did u find Qute with just nap 100 feeding the speakers? Was it better than Qute on its own?

back to your bi-amping question, have u tried the Qute feeding the bass and nap 100 doing the treble, Linn used the recommend using their bigger amps like li140 on the treble and lk85 on the bass as they surmised that the lk140 was better quality and therefore had a bigger effect to the sound if driving the treble.

Yes, it was clearly better. I tried both. The Qute on its own sounded great, but best sound was Qute into NAP100 with the Qute power amp off. It's a fuller and more complete, without losing any of the Qute's natural liveliness and fun. Via the NAP, it was as if a slightly dark veil was removed.The more I listened, the more I preferred it. 

On switching the NAP to the tweeters, yes, I did try it. Not great. My speakers are relatively insensitive and 30w was struggling. Maybe with different speakers.
