Magico S1

One thing I should mention about my audition of the S1 is that the deep bass was phenomenal. I played some pipe organ recordings with pedal tones in the 30 Hz range and it was very impressive for a 7" driver. However, I will say that the woofer was flapping like crazy to put out that kind of bass. Of 7 or 8 speakers I auditioned in the price range of $8k to $16k, the S1 had the best deep bass of them all.

Along with the amp I would imagine speaker cable selection would be critical as well?

Yes, that's true, Rja. Speaker cable effects will tend to increase as speaker impedance goes down. Atmasphere among others has made that point in some past threads.

Since it seems that speaker cable effects can't be entirely explained or predicted technically, at least in a manner that stands up when analyzed quantitatively, it's hard to give a complete explanation for that, however.

But among other factors that may be involved, resistance and inductance (or more precisely inductive reactance, the inductive form of impedance) assume greater significance in relation to speaker impedance as speaker impedance becomes lower. Which increases the consequences they may have as a result of the voltage divider effect.

Likewise for the rise in resistance that occurs at high frequencies as a result of skin effect, although whether that may be audibly significant under most reasonable circumstances is debatable. Also, although again its audible significance is debatable, lower speaker impedance is likely to worsen the mismatch between speaker impedance and the "characteristic impedance" of the cable, which will to some small degree affect inductive and capacitive energy storage in the cable, and waveform reflections and RFI pickup that may enter the feedback loop of the amplifier, if it has one.

There are probably other effects that are involved as well, but those are a few possibilities that come to mind.

What are the speakers you compared with at 8-15k price range?

There are several speakers at that price range that beat
bigger magico in term of deep bass I think.

I think you mean “proportional” bass, not “deep” bass. It is about time audiophiles distinguish between boosted midbass and actual extension.

Give the fantastic JBL 1400 array a try. Lower grain, fabulous imaging, deeper bass, play louder. But, most importantly, music. Beautifully made. Gorgus
