NAD M28 7-Channel Power Amplifier Review & Comments

Hmm, I thought that I had previously posted on this thread (hence my getting an email reminder for updates to the thread) but somehow my earlier, inoffensive, post seems to have vanished ...

Let's see if this post survives. This isn't a complaint againt this great-sounding NAD M28 amplifier specifically, but against all 7-channel amplifiers. Assume that you have a great deal of money, and a reasonable, though not endless, amount of space in your AV cabinet. You want to move beyond the previous standard of a 7.1.4 system to the new standard (which Mr Withers himself has at home) of 9.2.6. You have a 16-channel processor like the Lygndorf MP-60 or the Arcam AVR30 (which has seven Class G amplifier channels). My concern here wouldn't be the two subwoofers, but the nine base channels plus the six Atmos channels. Those come to 15 channels. And my point is that using seven-channel amplifiers, it's not possible to get to 15 channels with only one further box. If you used the Arcam, with its seven built-in channels, you still need eight more channels, which using seven-channel power amplifiers means two more boxes, or three in total. And using the Lyngdorf, with no built-in amplification, to get to 15 power channels entails using three seven-channel power amplfiers, or four boxes in total. Which is kinda a lot of boxes ... However, I guess that you could stick with three boxes in total even using the Lyngdorf processor by using this NAD amplifer for the base layer and then using something like the Emotiva XPA-11 (or its nine-channel version the XPA-9) for the other channels. Perhaps 8-channel separate power amplifiers might become more common in due course as we go beyond 7.1.4 systems.
I completely agree with you on this point Ken. In the modern immersive audio world, a 7-channel amp is arithmetically annoying. An 8-channel model makes more sense for the reasons you mention, or better still a 16-channel amplifier for a tidy single-box solution. It's for this reason that I've recently added the 16-channel Storm Audio PA 16 MK2 amp (review in the works) to run the 15 channels in my system.

The Pascal amps seem to be getting about a bit now. Dynaudio use them in their mega serious Core range too.

I’m looking forward to the review Steve.

Never had any issues with any NAD products I've bought over the years. My Dad still uses his 3020, bought over 40 years ago and its never needed any maintenance. Guess you guys were just unlucky. They make great products.
