The NDAC was not a copy and paste of the CD555 and certainly did not sound the same. There is more than just the Burr-Brown chip chosen to the sound of these things. Otherwise the CD555, NDAC, NDS and ND555 would all sound the same. They don’t.
So maybe I should consider the the Dac as an upgrade for my XPS NDX BT
How would that fair compared to the NDS
The ND555 is out of my budget
The NDX 2 is a possibility but I’m only using iTunes lossless so the NDS could be just fine and it’s sounds like some people think it still sounds better. It would be interesting to here a response from anybody using the puritan 156 with the NDS, NDX 2 or the ND555
surely they must be sounding different for that price gap, but can you reveal some more color on the the differences?
All the White Papers (or at least most all) are available for download from the Naim website under the Support page.
Thank you Richard!
@Michaelb , to put my question different… if someone offers you to bet 1:1 the difference in price between ND555 and nDAC/555PS (non-DR) with Furutech RCA clear line if you correctly distinguish the two in a blind test 10 out of 10 times, would you accept the bet?
does that mean that you had no direct experience comparing the nDAC with the ND555?
Great test that would be, along with a nds, and why not chuck in a second 555 power supply.
I don’t think you will find anyone willing to do it as any differences are far too close to call, if you can even hear a difference.
From the white paper Q&A “Why S/PDIF optical rather than coaxial?
Coax can sound better but optical has the advantage
that it prevents ground loops and isolates the ground
system of the source, which may be noisy, from that of
the Naim DAC.” @Richard.Dane , this is interesting and relates to our discussion in a different post about creating a ground loops when both nDAC and network streamer are grounded to chases and interconnect with galvanic conductor.
Looks like support is now under “Help” in smaller print near the bottom of the main menu, I thought it had been dropped on a first look at the “upgraded” website.
You can’t compare Nd555 , all in one streamer and dac vs the Ndac, only using a same transport and connecting by SPDIF to the Ndac and Nd555.
There are many threads on Nds vs Nd555 and Ndac vs Nds.
I have not found a person saying that Nds is better vs Nd555. A minority found the difference minimal, a majority significant.
Most also find the Nds , as dac, better than Ndac. A minority prefer the Ndac voicing.
Some compared Nd5xs2 into Ndac/ 555 ps. Unfortunately they said it’s not at Nd555 level. It would be too cool, as the former combo costs less than half of the Nd555.
For cost, an Nds/ 555 ps non dr but serviced is imbattable. Specially for local streaming.
Probably a number of ways to get there depending on how you’re viewing and on what device.
On the general web page it’s at the bottom under Services.
I have better things to do with my time.
So I will give you a different answer.
I was very keen to get my CDs out the way. I had many hundreds.
When I heard the NDAC and NDS I was not prepared to lose what the CD555 delivered compared with either. So the CDs stayed. The ND555 was another matter. Overall, I preferred it slightly with one PSU, but quite a bit more with two. So that’s what I bought. And that was before I found what Innuos can do to improve things.
Your system and preferences - musical, sonic and otherwise - may differ. But to claim that the CD555, NDAC, NDS and ND555 are pretty much the same because they share a common chipset without considering what the differences in their implementation bring to the table is simply inaccurate.
That very much depends on the music and system you’re listening to.
It does and that is the main reason why most won’t hear a difference.
As always you will only get to hear what the weakest item in the chain can do. I found that out.
It’s how the filtering is done and other things that changes the sound from the same chip.
But even so the difference between say the nds and nd555 playing from the same stored device is extremely close. Streaming, that’s a completely different result.
I’ve just moved from an NDac/555DR to ND555 and I’m afraid the ND555 is quite a bit better even with one supply in the chain. Connect up another 555DR and it makes the same leap again! Hear a piano note struck on an ND555 with two supplies and you will understand instantly why it’s so much better than anything else you’ve heard.
Instruments just take on more authority, better separation, greater dynamics and a better tone. Even if the DAC in the ND is similar to the NDac you have better isolation with the ND’s suspension, plus the added shielding. Couple this with a great streaming section and it’s really hard to beat. Downloads from my Core easily compete or better my LP12. A couple of years ago I couldn’t get close to an LP12. My old CDP555, given the right CD, could get close but rarely better!
I have had a ND555 for several years but had a couple of problems over the years my dealer loaned me both a NDS and NDX2 the4 ND555 is he best by far and I agree with your observations regarding piano notes.
Yes. Easily.
