Priority of Dr upgrade

I would recommend you consider service intervals i.e. If one of the above components is due a service it makes sense to get Dr'd at the same time as a service - you get an OK saving doing this.

In my 252/Supercap/300/NDX/nDAC/555 I chose to get super cap / 300 done first as I have an lp12 as well as a digital source ergo the uplift in performance would be on both sources.

My dealer was very helpful and was more than open to demonstrating  the differences so well worth chatting through and "hearing" the differences for your self. Whilst it's great Naim have given us the option to upgrading our old kit (well done Naim) it is still an expensive upgrade. 

Thanks

I would get the 300 DR first.

it is not your PS300 that will get DR by the way, it is the amplifier which gets new transistors and new regulation.

This is a jaw dropping, awe inspiring upgrade. 

You can google 300 DR review.

"Naim AudiDR technology was first introduced to our separate range of power supplies in 2012. It was then applied to our flagship Statement amplification system and adapted to handle the higher current demands. Now we have introduced the benefits of this technology to our core range of power amplifiers, providing the smooth, stable and low-noise power supply we know is vital to audio performance."

I kinda like the route Naim took!

PS's first then Amps!

I think amp would benefit the most from the DR upgrade.

Woo, I assume most of you will recommand me to upgrade the xps to dr first due to sourcing first concept.

Anymore comments here?

Can you have a home demo of a XPS dr I had a demo last week and of a new system the dealer did say that the dr upgrades to both the XPS and Supercap reaps substantial benifits and falls in line with the Naim suggested upgrade route source first.

Would like to have more opinions, please help to advise.

This is a bit of a chicken and egg type question in that as you DR each bit of your system you get greater and greater benefit as the synergy just grows with DR upgrades. I went from Hicap (non DR) to SupercapDR and later went from 250.2 to 250DR. I heard greatest benefit from the 250 upgrade but that could be because my Supercap was already a DR version and the DRing of the 250 had the dual benefit of itself going to a DR but also benefitting from the SupercapDR.

I am a 'source first' bloke and my system has Monkfish tendancies. Having said this I recon you should get the 300 DR'd first. But you will not get the full benefit of this until you DR the power supplies.

One more opinion for you as you asked.

If you still have the CDS3 in your profile, and intend to keep it, you might consider upgrading the XPS to a 555, in which case, obviously no point in the DR upgrade. The rest of your system seems pretty well balanced, so I can't see you're regret doing either of the other two.

Heard the difference between NAP 250 and 250 DR. Based on that I would suggest power amp first. 

I have a 552 DR but never compared to the non-DR version.

Depends on your timescale. Even if you book the 300 in for the upgrade now it'll be several months before it'll happen so you may well be able to afford one of the other upgrades in the meantime.

DaveJ,

Why do you say it will take so long for the 300 to be upgraded? My XPS and Supercap were DR'd in 2 weeks. Is there an issue I am not aware of for the 300's?

Ken

I think it's just a general backlog, my 300 is in a queue (been 2 months) and am patiently waiting for my slot - hopefully not too much longer now.

Hi Ken,

Only because I booked mine in back in January and there's still no sign of a date. It may just be because the demand for 300 upgrades has been so high - and understandably so, I was hugely impressed when I made the comparison - but it'll have been over 3 months this week.

Cheers

So are you saying you have been without your NAP300 since January or just waiting for a date for the upgrade to be done?

Ken

Do

I think 300 is my last dr upgrade target.

Do you think if do the dr upgrade of supercap is more prefered than xps ?

The logical route in my eyes would be xps, 300, super cap ...

I advise focus on SuperCap first. The Naim system is centred around the NAC performance, and the DR upgrades to the NAC power supplies has phenominally (to my ears) upgraded the performance of the NACs to the extent they are like new models with the 552, 252 and 202 seemingly improved the most to me.

Once you have done the  NAC, then whether it's source or amp next perhaps depends on source... But I suspect for most the amp would be best next. I find some Naim sources better non DR'd, the NDAC with a 555PS for example, but the NDS very much benefits from DR.

Hi simon,

You mentioned very good points for me, thank you for the input!

Following Naim's lead, I assumed order was relative towards the evolving Naim Sound!

R & D working with Statement technologies

2012 Dred Pre

2014 Statement

 SL technologies

2015 Dred Amp

However, judging from Forum feedback, perhaps Naim's greatest accomplishment was it's trickled down Dred Amp technologies.

quotes from Review on 250DR

""The result is a power supply Naim claims is 30 times quieter than that of the previous NAP 250, with separate supplies used for each channel in the NAP 250 DR, as in the NAP 300 DR and NAP 500 DR.

What immediately became evident was the additional clarity the NAP 250 DR brings to the party, while still maintaining that punchy, explicit and vibrant NAP 250 sound.""

Initially I suspected Nac, followed by Nap, but to my surprise The Forum is reversing that order!

I guess adjectives like clarity and quieter, aren't that subtle to the ear!

Just my two cents!

Allante93!

only your ears can decide - they did for me. The discrete regulation of the NAP250.2 is certainly no slouch.. seemingly especially with the appropriate speaker... and clearly the new 250 builds on this.
