My N272 is now about two months old and I am enjoying it very much.... today I have upgraded the power supply from a XPS2 to a XPS DR... I know I will have to go through the 'burn-in' period - but fresh after installing the new XPS DR and giving it about 1 hour of warm up time, I was curious to hear how bigger a difference there was between the N272 running on a XPS2 vs XPS DR. I can say already that there are differences - bass is better controlled - initially I thought that the bass was...
I had a 200 on loan for a few weeks while waiting for a 200DR to arrive. I tried the following permutations around 202/200 pairing 1) 202 + NAPSC + 200 2) 202 + NAPSC + HC2 (non DR) + 200 3) 202 + NAPSC + 200DR There was an improvement to perceived dynamics and soundstage (with the usual caveats of my individual hearing, speakers and room) with 2 over 1, 3 against 2 was more balanced and tricky to call. 3 had more detail, but didn't quite sound as lively as 2, however 2 seemed better across...
i have a 172/200DR/ovator S400 setup, on fraimLite with Naca5 spkr cable... in this setup i had tha chance to test an year or two old NAP200 (non-DR) and a few weeks old NAP250DR... i posted my findings on several topics, and i found that, from those 3 amps, the best VFM is the 200DR. i haven't compared (yet) the 200 vs 200DR with 202, is was planned with my Naim dealer and friend, but we haven't found yet the day to relaxingly do that... it will happen though, one of those days. on my...
Hi Guys, Thnx for all your tips&tricks plus off-topic discussions ;-). I have not decided yet, total price (including DR upgrade) will be €3600 euro (= £2652). Meanwhile I will just enjoy my 272/250DR and think about it. Rik
+1 I'm really keen to understand how the 500DR compares to the 500. Because my 552 was away in Salisbury for weeks it wasn't clear what the DR and service improvements were. My audio memory isn't that good.
That's good then. I've never been bothered by the thump, but it does seem to upset some people to an excessive degree. So as well as massively improved sound, DR banishes the thump. It's a win, win scenario.
Old - On turn on there was a loud thump heard from the speakers and on turning off, a pop coming from each speaker, at about the same time, after 20 or so seconds from pushing off. new - very small thump on turn on, non on switching off.
The 500DR is still breaking in, only couple of days old. As in other DR upgrades, initially the sound is a bit "polite" the bass is deep but less punchy, background noise is immediately lower enabling more details and better imaging. With time, bass will take authoritative punch, the sound will be highly dynamic, harmonics will be beautifully presented and more music will be extracted from the source. Worth investing.
Interesting to read this and the NDX thread posing similar questions. It does sound very much like a potential reduction in what I get from the CDX2 with XPS2. CD will remain the primary source for a long time. I've yet to hear a streamer in my price range which comes near. Streaming will be more for wife and child with Apple devices initially, so the quality of cd output is the primary concern. A second XPS2 is not on the agenda but equally nor is the sale of the CDX2. As said earlier I see...
The CDX2 is and will be my primary source for the foreseeable future too. I don't have an XPS2 on it yet, but after hearing the improvement, it's an upgrade I can't live without! Once on, it will never come off.
I originally tried a stock XPS on my nDAC. It was nice and took a bit of grain away but very soon after I managed to get hold of a a second hand 555PS - they are out there. This really transformed every aspect of my music. Much more lifelike, wider and deeper sound stage. Loads and loads of hidden detail suddenly comes to the surface that I'd never even noticed before. Then of course you're addicted.
How do you connect your Mac to the nDac? I found in my system that different USB-S/Pdif-converters make a huge difference, maybe even to the point where a nDac with new firmware can happily live without external power supply
Hi Ive had a few demos recently. Playing around with power supplies in different parts of the system. The biggest difference I heard by far was the power supply on the source, every time. Adding a PS to a pre amp did obviously improve things too but nowhere near the same level. I heard the 272 with PS then NDX with PS into bare 272. (NDX was used as dealer didn't have a CDX2). No contest. The NDX kept in performance! The 272 was a small gain in comparison. I too have a CDX2 analogue only. I...
Best thing to do though would obviously be to get in touch with a local dealer and arrange a morning for some demos. Ive not heard a 202, but I'd guess there would only be a subtle improvement with the 272. Just a guess. More of a sideways step to add a streaming source, rather than a pre amp upgrade?
At the risk of repeating myself for earlier versions of this same question.... 1. Dump pure music for Audirvana 2. Its like the Dac firmware upgrade, a no brainer. 2. Get the best PS you can afford 3. Paul Hynes SR7 on the mac. I use a dual rail that also powers my Weiss int202 4. Enjoy the music.
if you can stretch to a used 555PS - in my experience preferably a non DR one - it will really compliment and transform the Naim DAC. Yes the DR thing on the 555PS was very noticeable on the nDAC. But this was all with the previous DAC firmware. Simon
Well, I can vouch for the XPS DR on the DAC. I haven't done any comparisons against the other options (except my vague memory of my originally XPS2) but I'm very happy with this combination together with Powerline and Hi-line.
I tried a home demo of an XPS2DR on my nDAC to see what it offered over my XP5XS. There wasn't enough of a performance lift for me to justify the price difference. I felt the XP5XS offered about 80% of the performance of the XPS2DR but at half the price. A 555PS on the other hand was a quantum leap over the XP5XS. Like Simon-in-S, I tried both a 555PS DR and a non DR 555PS on my nDAC and preferred the non-DR. Non-DR versions pop up from time-to-time.
I tried XP5 XS recently with my nDAC but in my system the result wasn't what I hoped for. I mainly noticed great amount of power and weight added to the bottom end but to my ears it was too much. I have rather big speakers (ATC SCM40 v2) and not that big room (around 20m2) where I use them so there's plenty of bass power already. With external PSU, it went overboard. I was hoping to get similar results with the PSU update than I got with the nDAC firmware update recently. Maybe some day I'll...
Hi Nick The improvement of the Superline over the humble Dynavector P75 mk II, even with the optimal Naim Z foil resistor value, was not sufficient to convince me to buy one if the SL was to be powered off the pre-amp. I found the SL + SCDR to be an utterly convincing music maker. However, it would be a £7k phono stage, not a £2-3k one in this configuration. In the end, the funds went into improving the turntable from the Xerxes 20+ to the Vertere MG-1. The improvement with the MG-1 has been...
Hi Nick I have a Naim factory serviced, POTS8 52 + olive Supercap. A year or so ago, I tried a Supercap DR as part of an extended home trial of a Superline. If you search for a thread called "The perils of a quick Superline demo", started by Foot tapper, you will find several posts about the merits of olive SC versus SCDR on our NAC52. Hope this helps, FT
i have in 2nd system a pots8 NAC52 powered by Supercap DR (you cannot DR an old style supercap as far as i know) and driving NAP135s in Linn Kan1s. This is a suprisingly good, if not a bit 'old school' system... and sometimes gets me asking myself some embarrassing questions... enjoy... ken
As Ken mentions you can't DR an olive SuperCap. Given your SC is 15+ years old it would certainly benefit from a service. For a while I ran a 52 with a SCDR. It did make an improvement. As an alternative to SCDR you could consider servicing your olive SC and then also adding some Super Lumina cable to your set up.
unfortunately that is the reality on the naim forum. I've heard many rigs upto 552/500 now, and my advice is to proceed slowly, no need to rush into anything. Once you get the 300 DR upgrade, you may feel nothing else is needed. It is a major upgrade that makes the most of all upstream components.
I recently had my 18 year old supercap DR'd along with servicing the the 52, the results were nothing short of spectacular, I'm also using a NAP300. I would recommend it highly, I couldn't afford a new 252 so this was a good upgrade. I was amazed at the new level of detail, this was one of the best upgrades I've ever done.
i wonder how supercap DR works compared to 52PS? 52PS is clearly better than supercap, partly due to the larger number of supply caps (and that was the view of service department a few years ago when my 52/52ps was rebuilt -- I was offered SC crossgrade but recommended against it). But 52PS is fixed function whereas supercap is universal function which for many might be a big deal. I suspect SCDR has overtaken 52PS, and significantly so.
I changed to SCDR for my late 52 and put my olive SC on snaxo duties. It kicked everything up a gear, positively impacting both LP and CD play of course. Like you Nick, I use a Superline. Unlike you, I power it from the 52 rail directly, since I have too many boxes as it is with an active system. The SCDR helped the Superline as well as the pre-amp for that reason. So I would have no hesitation in recommending SCDR as an upgrade for you, especially if you are going to DR your 300. And then...
