NAD M51 Direct Digital DAC Impressions - Page 70

post #1036 of 1540

am getting the oppo 105 because i wana get the chance to play my sacd discs , if u imagine a lot of people buy expensive usb to spdif converters  costing about $500-$1400 . if i buy the oppo 105 i dont have to buy the converter , and  ill have the chance to play my sacd discs and dvd audio discs , and dvd  thru the nad , and also get the chance to do dsd playback but not thru the nad , but from the oppo itself , its not like an upgrade , its like getting features the nad does not have and integrating it with the sysytem .

Sounds good.  Please let us know how it works out; e.g. does Oppo improve SQ when used as a USB-SPDIF converter to M51 and whether CDs played from Oppo sound better using 105 DAC or M51 DAC.

 

I'd be keen to learn what you find. I cheaped out and bought the 103D to save money towards my M51.

 

BTW; there is a 105D just released or coming soon...if you feel having Darbee for video would add value for you.

All,

Just got a new M51 (Black!), and noticed firmware version is 1.43.

Haven't seen that version mentioned here.....

Yes, the M51 is superior in all count to the Oppo sound wise.  The Oppo is an all-in-one great machine though.

Aha!  Mine is only one month old.  It has v1.42.  I've been reading about sonic benefits of 1.39 and wanted to try...even learn what the updates actually changed.  Anyway, I wrote to NAD and the responder said she'd never heard of 1.42 and that 1.41 was the latest. I've tried writing again. Thing is, I (and probably you) would like to have a copy of 1.42 or 1.43 so we have the option of reverting back if 1.39 is no better.

Please let me know if you find out anything.

Could you tell me more? ...describe the differences.  Was it just more bass with the 1.39 or something more?

 

Don't suppose you ever listened to 1.42 or 1.43?

 

Cheers

if they add dsd I am on board. on the other hand 35 bit pwm might already be better.

I think this sounds great with V 1.43 in my system, no desire to backtest.

 

How can you conclude you like 1.39 "best"?  Where did you get 1.42 or 1.43?

 

BTW, I've recently tested the Oppo 105 as well as the BMC PureDac in my system.  

 

With their nasty Sabre dacs, just no comparison.

 

Actually, I like the Emotiva next best (dual AD 1955's) - detailed and smooth, like the M51.

 

And for the $499 price, loaded with features, a steal.

there is another bargain to be had with four pcm1795's too..... I still find the conversion by the zetex very interesting.

 

oops, that's two times pcm1795. not four. my bad.

All that I know re FW is:

When NAD released 1.41 to replace 1.39 and users started updating, more than just a few of people on forums reported that the SQ was not as good after installing 1.41. Many users then reverted to 1.39 or avoided the update.

Apart from the two of you reporting that your units arrived with 1.43 and me reported that mine arrived with 1.42, I have found no other reference to any FW other than 1.39 and 1.41 even existing; let alone where they can be downloaded or how they sound compared to 1.39 or whether any bugs were fixed.  I have spent many hours searching for this info via web searches and by asking NAD...so far to no avail.

 

I'd love to hear from anyone with more info or anyone who actually compared 1.39 to 1.41.  I doubt that anyone has compared 1.42 or 1.43 to any other FW (how would they find a copy to do the update?).

Starting to wonder if 1.41, 1.42 & 1.43 are identical.

A mystery - it would be great if NAD catalogued these versions and changes.....

Agree wholeheartedly.

 

For the record, this is what NAD told be about v1.41

 

The M51 firmware upgrade V1.41 made the following changes:

• In compliance with European Eco design regulations, the “Auto Off” feature is added in the Setup menu. When “Auto Off” is set to “On”, the unit will automatically go to standby mode if there is no audio detected for 30 minutes.
• Address intermittent occurrence of audible ticks or clicks at certain volume levels.

DO NOT DOWNGRADE TO 1.39!!! I bought my M51 this month and i recently sent it back to NAD because the downgrade from 1.43 to 1.39 bricked it. They told me they will try their best to fix it but that there is no guaranty it'll work.
