....forum search perhaps?

I saw it, touched it and heard it in Dublin on Saturday, although they say that it will be 30% improved by the time it is launched. What do you want to know?

I know that Hook sent a reply to my last message, because I have a copy in my email, but it seems to have disappeared from here. Anyway, I would just say that the atmosphere at a show such as Saturday's in Dublin is not really conducive to critical listening, but after seeing, feeling and hearing it, I will certainly look forward to a critical listening when it is launched.

Has it changed to Mu-so ?

It would seem-so! I can't say I noticed the hyphen before.

I don't care what it's called. I heard one today and ordered one. It's a nice sounding bit of kit for the money,  and far better than the B&W Zeppelin Air I have or any Sonos I've listened to, that was just listening via Bluetooth.

As well as John Lewis Naim now Naim have negotiated a deal with Apple and they will be sold in the Apple Stores.

I wish it was available in black but it's still very stylish and will look and sound good in my breakfast room. 

You just became part of it: user forums, social media et al.

A review I read of "Mu-so" stated it will sell for £895 and is powered by six 75-watt digital amplifiers.

Is this the first Naim product to use digital amplifiers?

If the Mu-So exceeds the B&W Zeppelin Air, will it sound better than the B&W A7 or the Bose SoundTouch 30 Wifi Music System?

From what I have heard the answer is yes and by no small margin. I have lived with the Zep Air but have also heard the top end Sonos and A7. The Muso did sound surprisingly good.  It's very good VFM IMO. I think it also looks more stylish.

No, the N-vi also used digital amps if I remember correctly.

This is a bit off-topic but could somebody give me a simple explanation of how a digital amplifier works?  I've always assumed that the phrase was just a marketing phrase for an analogue amp with a DAC on the front.  At the end of the day the output has to be analogue, but please educate me if I'm missing something.

Thanks

Digital amplifiers - if not purely limited to the marketing brochure where your explanation could be correct - is usually more accurately referred to as a Class E amplifier. It is a switching amplifier - and works not unlike the principles of a SMPS (switched mode power supply).

The advantage of class E is that they are very efficient and can be designed in relatively smaller spaces and can be designed to provide phenomenal power (like football stadium PAs etc) . The disadvantage was that until a few years ago their performance wasn't generally too impressive - but techniques and understanding of how to mitigate certain shortcomings have improved significantly and so I understand has also the performance.

Thanks Simon.  And to continue my tutorial, what is a Class D amp?
