It allows bass management of multiple subwoofers (bass optimization within Dirac Live)... and the sub pre-outs will be XLR.What would the bass control modules do?
Each speaker is separately measured by Dirac so each sub (if connected to separate outputs) are measured for timing and for frequency.It allows bass management of multiple subwoofers (bass optimization within Dirac Live)... and the sub pre-outs will be XLR.
I'm curious if Dirac sets the timing between mains and sub with the current RCA sub pre-outs? I assume the current sub pre-outs are summed.
Thanks for pointing out these real world user issues, like you I'm hoping NAD can produce software upgrades to solve them. Looking forward to your comments on sound quality and Dirac experience.Over the last two weeks I’ve been using my new M33 so I think it’s time to update from my earlier post.
As you know if you read this and other audio forums, I’ve been a great fan of the NAD Master Series, in particular the M12 preamp and M32 integrated. Both have built-in DACs, phono stages and can take the BluOS module to add a streaming facility, all for a very reasonable cost.
The new M33 with Purifi amplifier module was announced ages ago but has only just become available and I’d been anxiously looking forward to getting one to replace my M32. I gave a quick comment on its sound earlier, but I’ve held off commenting on other features after discovering several aspects I’m less than happy with.
Contacting NAD’s Customer Service guys since buying the M33 has been frustratingly unsatisfactory, because they are mainly working from home without access to an M33. Frustrating because there appears to be a number of very basic software problems that seriously reduce the usability and “friendliness” of the M33 compared with its processors.
Today, after I suggested that my individual unit may be faulty, I received a phone call from a more senior guy in NAD (let’s call him Bob) who was most helpful in understanding the points I’d been trying to highlight and has promised that the design team would carefully look into them. This has come as a great relief and grounds for optimism as this clever box of tricks could and should be a fantastic solution for those of us that want great sound without numerous boxes and a snake-pit of over-priced and never sound-enhancing cables!
I’ll mention a few features of the M33 that I consider badly thought out and should in my view be changed, hopefully by a significant upgrade in the control software
Selecting the Source can’t be achieved using the remote’s CH/Source up and down toggle. That’s surely what it’s for!
The comprehensive Settings menu can’t be explored using the remote. The app offers access to a few settings but many can only be reached via the touch screen. By contrast the same remote can be used to explore (and make changes to) the entire menu of Settings on the other M series using the set of 5 central buttons – up, down, left, right and Enter. The M33 has wrongly commandeered these 5 buttons for:
Changing Source (should be handled by the CH/Source buttons - adjacent to Volume buttons)
Selecting Next and Previous track (should be handled by the buttons marked for these purposes - towards the bottom of the remote)
Pause / Play (should be handled by the buttons marked for these purposes - towards the bottom of the remote).
I mentioned the inadequate (for non-techies) instructions for running Dirac Live. Even after reading Dirac and NAD papers on the subject and watching Youtube videos, there were features that are unexplained, eg how to choose the Volume Settings prior to measurement.
Those who use subwoofers supporting small main speakers (LS3/5As, etc) may be disappointed that the M33 has lost one useful feature that the M12 and M32 offer. With those units, you could choose to protect your main speakers from the lowest frequencies allowing greater volume without fear of speaker damage, but not with the M33. You can still select your crossover frequency for the sub but not for the main speakers.
I’m encouraged enough following my long conversation with Bob that I won’t be returning the M33 to the dealer and reinstating my still-excellent M32. These corrections and improvements won’t be done overnight, but I’m living in hope that this product’s unexpected disappointment factor will soon be replaced by the anticipated best-on-the market feeling.
More to come regarding Dirac and other sound-related features, though I won’t be commenting on any of its analogue abilities as my system is all digital.
