NDX, NDX+DAC, UQ and ADS2

Posted by: Julian H on 05 April 2011

Yesterday, David [mrclick] and I travelled to that well known Leicester based emporium to have our LP12s looked at. Mine was a minor anaesthetic-free operation of a new Akiva and David’s deck had some much needed open heart surgery. We both took the opportunity to have the new Dynamik [or Dynamo as David calls it] PS upgrade for the Radikal.

 

Anyway, enough of the analogue  stuff.

 

I had arranged with Peter to have a good listen to some of the current streaming kit. So, dutifully, his digital expert in the shop, Phil, had set a nice demo for me. Unfortunately, he is off on his holidays this week so I was keenly attended to by Tom instead, who went through the whole set-up at the shop with me including recommending ideal home networking solutions and showing me how to use various apps on iPAD for remote control.

 

The remit was that I am looking for a streaming source for my study but wanted to check out how far this “new” technology had come for potential main system use in the future. Previously Peter had lent me a Rega DAC at home for a few weeks, streaming from my iMac. As reported in an earlier thread, this combo left me completely cold. I have also been lent the UnitiQute by John [fixedwheel] for a few weeks and I thought that was something special so, there was some definite promise in this new technology for me!

 

In the demo room we were partnering the sources with the Linn Akurate Pre/Power combo [don’t ask the model numbers, I haven’t a clue] and Kudos C30’s.

 

I chose two tracks from the shops ready ripped [FLAC] music “store”, on a RipNAS, Led Zep’s Whole Lotta Love and Goldfrapp, Shiny and Warm, being representative of a large chunk of my listening.

 

First up was the ADS2. I listened to the tracks a few times in full on this to acclimatise myself to the system. At this point in proceedings I was completely struck by the sheer resolution and quality this box was providing. Playing at a far higher level than I could believe at the price [£4.5k?]. Stunning!

 

Next was the NDX+DAC combo [£5.3k inc interconnect?]. The thing that struck me was it sounded like a pukka Naim component. Immediately engaging, really my kind of thing, and pretty much what I had hoped for given my previous positive experiences of the UnitiQute. I was quite surprised about this though because in the past I have been quite vocal about my feelings towards the DAC. The negative about this combo is the completely inferior resolution revealing nature to the main competition, the ADS2 in comparison. As a vinyl head, I couldn’t live with the ADS2 but respect its qualities. I could live [love?] the NDX+DAC combo.

 

The drop in performance when removing the DAC from the NDX is quite marked, moving it even further away from the Linn piece. It all goes a bit soft, undynamic, less well resolved and looses a bit of “swing” in comparison. It’s a shame that Naim do not make a DAC free head unit to partner the DAC, I guess that’s another item thatSalisburyare working on…?

 

Finally was the Cutie. And Cute it is too. Running it as a source in the system, after a few minutes to get used to it, all the good memories came back and I remember why I liked it. It still does the fun factor very well even alongside the more superior components. I guess the difference between the bare NDX and the Qute is similar to the difference between the NDX+DAC and bare NDX.

 

In summary, I will probably end up with a Qute for the study [with my N-Sats] and have gained confidence about having a serious digital source in the future for the main rig. As regards the NDX+DAC vs the Linn ADS2, I would not like to predict what anyone else would choose but I would say, either piece is a super source but with different presentation and neither should be discounted for “brand preference” reasons. Only buy with your ears!

 

Cheers, Julian

 

Ps – Radikal Dynamik…., wow

I did it in Naim system. KDS is softer (which is especially pleasant on the old Red Books) but very relaxed, especially the bass is blurred and lowered comparing to the punchy nDAC/XPS.

 

Am I alone to hear this 

I have not done that A/B just reporting from seperate occasions so subjective.

 

Not sure if you are alone but the whole blurred bass thing didn't reach my ears with either the KDS or the ADS. In particular the ADS at home has a clean dynamic bass delivery which on red book CD is on par with what I used to hear with the CDS3. Of course this may be speaker dependent to quite an extent.

 

On hi res music this continues but there is no CDP reference to compare against .

I've said before on this forum I used to own a CD555, nDAC and KDS, so I've had the opportunity to try all three sources in my 552/500/Audiovector system. Like Geoff I've not heard the soft, slow bass that's been reported for Linn streamers. The result of having all boxes at home and choosing my preferred digital source is that I now only have the KDS. I've removed 4 other big black boxes from my rack

I have to suggest that possibly 552 takes much better grip over the KDS output stage than my 282/HC and that's possibly a reason why 552 owners don't hear any problem with KDS bass.

I tried nDAC vs KDS in Naim and Cary all-tube systems and in both cases switching the input on preamp resulted in a very serious change in bass punch.

I have tried KDS with 252/SC and it didn't improve on bass a lot.

 

Graham, I don't disparage your experience but I would love to see anyone else to report on the same findings with KDS/552. Your particular case could be very system specific. If it comes true I will happily change nDAC/XPS/282 for KDS/552 which I can afford. And I shall definitely share new experience on the forum.

 

Unfortunately for the last 20 years I had several cases when paying double or triple price over existing system had brought very small advantage in musical enjoyment (if any). So I start taking more care on such investments.
