(snip)...
Not sure if it's been mentioned, but the miniDSP SHD is an alternative at a similar price point (not sure about how good Volumio network streaming is). It has real balanced outputs for the low pass and high pass outputs.
how would you rate your miniDSP vs the Cambridge unit? I am also interested in the miniDSP SHD... although it seems a bit light on the specs vs something like the TEAC NT 505
i have not heard either unit

I still think mine sounds good, and gets better by the day. Like many other components, it is very particular about what you feed it. Bad recordings sound bad, great recordings sound great. I keep hearing from folks that think it is harsh, bright, etc. Maybe because I'm a trumpet player, I think if anything it can err on the side of being a little laid-back and not as engaging as the best stuff I've heard and owned. When I auditioned it against an M12, this was my takeaway, too - it did not seem as "energized". However, like I said before, that was a C658 straight out of the box vs an M12 with at least a few hundred hours on it, if not more. The M12 is also another ~$2500 if you add the BluOS module.

There has been a lot of criticism about the choice of chip set for the C658. Please forgive this very naive and stupid question, for which I'm pretty sure I already know the answer, but is there a way to upgrade the chip set, or is it like trying to perform a brain transplant? Again, apologies for a stupid question, but I'm curious if that might be an option down the road.

There's no changing the chip. A lot of people on the internet make a big stink about DAC chips but I find it to not be all that critical. Sure it's important to some degree but there are other factors to a DAC like the analog output stage that are extremely important. Having a good chip doesn't mean the DAC will sound good and having an ok chip with a fantastically designed DAC will probably sound great. The PS Audio I had is a perfect example. It had no chip at all, since it is software based, but I had the DirectStream Junior and it doesn't sound exactly the same as the full size DirectStream (senior?) despite running the same software (the same "chip").

@CDLehner I'm wondering if you're really getting MQA via Roon on your NAD C 658. I just did more research on Roon's website and it indicates on all NAD products that "MQA decoding via RAAT is not yet available with this product." So you are saying when you stream MQA songs via the Roon app (not via BluOS app) that the MQA logo/light appears on the front of your NAD C 658? I can't get it to happen and based on the Roon website info, it doesn't work.

Yes; quite right Solomente. Sorry.

I guess I was recalling, seeing the MQA light-up...from when I was using the BluOS app. In ROON, I do feel like I'm getting MQA decoded...from the "signal path" saying so; even though it doesn't trigger the light...probably because of the not "certified" issue.

Sorry again, for any confusion.

As long as you have it set in Roon for the device to handle MQA as "Decoder and Renderer" in the Device Settings, you should be getting full MQA playback. You can confirm in the Signal Path info.

Hi Brian. Actually that's not correct in this case because BlueSound and NAD products can only decode MQA via BluOS and not via Roon. There is an outstanding issue (since 2017) where BluOS isn't fully compatible with Roon RAAT and does NOT work with MQA if you choose decoder and renderer. There are many posts about this in the NAD/Bluesound section of the Roon forums. You have to set it to Renderer only and let Roon do the first unfold. From there, it's not really clear whether BluOS is doing the final decode or not. There is no MQA light on on the NAD, but the signal path in Roon seems to indicate the NAD is decoding it. It's quite confusing and frustrating, actually.

Oh wow. I thought that was fixed a while ago!:confused: Thanks for the correction!

Hi,

I just got my NAD C 658 but i am not able to open any DSD file (DSF or DFF).

I tried both options, connecting USB disk or accessing my NAS via BluOS.
In both cases the DSD files are just not displayed.

The only option that I've found is using BluOS app in OSX/Windows that includes below feature:

"Initial DSD Playback requires the BluOS App for Windows or MacOS. In Settings. Playback, Turn on Enable DSD Playback. Using the Browse button, locate the DSD files on your PC. These will be copied and converted to PCM and available to all Bluesound Players in all Apps once completed. The original DSD files will not be altered"

Obviously this is not what I am looking for.
if NAD C 658 supports DSD file (as specified in the technical specification) I aspect that it can natively play a DSD file rather then offering a tool to convert to PCM/Flac.

Please let me know your experience and if you found a way do it.
In the meantime I've raised the question to NAD support.

Thanks!

I received my Teac NT-505 today. Still auditioning, but initial impressions are promising. For one, it’s analog sounding - not colored, but musical while still being revealing. I’ve been listening all day today and have 0 fatigue so far. Compared to NAD C658, I was hardly tolerating more than 30 minutes.
Volume control is good, I haven’t noticed any loss of resolution so far. It definitely blows BlueSound Node 2 out of the water. This thing is totally in a different league.
The streaming app is not as good as BluOS, but it does the job. It’s the same app that Lumin uses. Having said that, I haven’t run into any bug either. Also, it’s roon Ready.
I’ll post a more detailed comparison with C658 in a few days. I still have the C658 sitting in my rack.
Really, really looking forward to hear your comparison Teac NT-505 VS Nad C658! Any thoughts to share with us?

I have ordered the C658 here in Sweden, but the more I read about the DAC-chipset used, the more I am thinking of cancelling my order. I have written to NAD to get some technical specs, but no answer...

If the C658 have had a DAC comparable to C510 or M51 that would have done it for me.

I think perhaps part of the issue is the upsampling DAC. I believe it upsamples to 384 kHz! I would prefer a DAC that does no upsampling and, at this point in time, I don't believe there are any available settings (to turn off upsampling). I did return my C658 and I am now looking at the Woo Audio WDS-1 to pair with my Bluesound Node 2i. The WDS-1 does take the approach of no upsampling and reviews indicate that it's strong suit is "tonality", which I interpret as being very good at re-creating the natural resonances of instruments. I did not hear that with the C658.

I figure that this is the DAC chipset used in C658 according to NAD's specs on their site; -118 db THD +N / 32 bit ESS Sabre.

ES9008
No of chipsets 1
DNR 134
THD +N -118
Channels 2
Bits 32
Sample Rate 192

Hello everyone, This is my first post on this forum. My name is Mark, I’m from Poland. Very glad to join You. I want to share my experience with nad c658. I own Bluesound node 2i, yearlier yamaha np s2000, I did wait and have a lot of expectations with nadc658, quite good ess chip, xlrs.....I ordered and I.....Send it back. It does not sound any better than bluesound node, really. My opinion. One more thing, the gear was warmed, demo. The strangest was test xlr/rca....I can confirm, it is ridiculous but rca sounds better than xlr, I was very surprised to discover that.
I use only tidal so user friendly app is a very important for me.
Now I consider teac nt 505....audiocat, please tell more about Your impressions and app. You said it is not as good as BlueOs...can You specify disadvantages of teac app and overall sound quality. Would You again exchange nad into teac?
P.S Sorry, english is not my native language

My C 658 / C 268 / Revel M16 system sounds amazing. I wish Dirac Live was ready from the get go - but it should be here soon.

I would strongly advise anyone getting caught up on claims about the specs for this chip vs that chip and just go try it for yourself first. Think about how long you can play those games for with ANY gear. Folks at NAD have a pretty strong track record with the DAC/Streaming thing - and this piece is just plain unique. It has (or soon will have) a set of features that you literally can't touch (Dirac, phono, BluOS, balanced outs, sub outs, 2-way Bluetooth, quality headphone out) on any other piece near its price, looks great, sounds great, and has performed for me without a hitch in all modes. And even if there are different chip options out there - most folks that have any experience with Dirac would agree that the differences Dirac can bring to your system are far more significant than the incremental differences that chip changes can bring. Comparing it to the TEAC and the other pieces mentioned here (as good as they might be) isn't really apples to apples. Qobuz and Tidal via Roon sound incredible on it. Stays in great sync with my C 390DD via both Roon and Bluesound apps. Very fine and pleasant to use volume control. Easy to read display - although navigation is a bit different.

I would add that the room I have this system in is VERY live and small. While I can understand where some of the critique about it sounding very bright come from - I would call it revealing instead. Full of moments where I have heard things for the first time. No listener fatigue in my experience.

I am guessing that once the software updates come through there will be plenty of stellar reviews to follow. Doesn't make much sense for pros to eval it until then.

Give it a try and enjoy as I have.

I agree with regards to the chipset. More pressing is the equipment you have hooked up to the little bugger. I have a set of active speakers with ribbon tweeters. I have to know the Dirac works. The XLR outs not sounding like the RCA is another gremlin

I'll have to fiddle with that. I'm running mine, straight to active speakers; so "long" ICs are a must...and I much prefer to go balanced.

But, if the sound is better with unbalanced; that'll be a real head-scratcher. :confused:

I have used c658 for a month now. Use it as a preamp with adam t5v. I like the sound and and compaired to my earlier stream unit Yamaha Wxc-50 it sounds much better, one can hear the details much more clearily. The Blueos app works well, and Tidal MQA is just outstanding. Don’t understand the issues of fatigue when using c658 ar all. I think it is marvellous.

Same here - it is doing exactly what I expected it to do when I bought it. I would expect better sound from separates, and have always chosen that path in the past. My criteria has changed, and this thing checks an impressive array of boxes, and sounds very good doing it (at least in my system). I did not expect it to sound as good as the M12, and it does not, but I don't think the difference is worth $2500 for my intended use. NAD is not going to sell something that competes head-to-head with their Masters series for considerably less and risk cannibalizing sales. If Porsche put 911 engines in their Caymans, nobody would buy a 911 again.

Hi Mark. Have you looked at Pioneer N-70AE? Very good reviews here in Sweden and Internationally. I will try C658 for a while (hasen´t been delivered to me yet).

I´ve been really digging into the NAD´s DAC. First NAD stated 35bit and 844kHz, than I read a reply from their support stating they use ESS9028Q2M, in one spec sheet (probable pre-release) 115 db, and now finally 118db 32 bit Ess Sabre. Do they know what they talk about..? Anyway ESS Sabre S9008 is the DAC inside the C658.

Otherwise I will take a look at and try Pioneer N70-AE or Teac NT-505 (where are all the reviews for Teac???)
