I know this may have been posted before but is the non DR 250 a better match with lean/ fast speakers to give some bloom and richness
I previously had a 252 SCDR non DR 250.2 and this worked really well with my PMC fact 3s.
Now have the non DR SC but the DR 250 amp with a full Vertere Redline loom Chord MScaler TT2 with the PMCs still
Just wondering to add weight and smoothness would the full non DR be a better balance
Hi. Thatâs a memory teaser but the DR brought a welcome lift to my system when I went from nonDR250 to DR250. My SuperCap was DR in both cases.
Couldnât live with the old 250.2, in fact when back to the 200, but the 250(DR) was superb.
Difficult to say how it would work with your non-Naim components but in my all Naim active system mixing of DR and non DR components (252, SCaps and 250s) always fell slightly short of what Iâd hoped, as evidenced by it all coming together when Iâd had them all upgraded. I would say that the DR components are simply better, rather than DR doing some things better than others. âWeightâ would definitely come more with DR amps in my view. No downsides of non DR to DR in my experience.
In your system it is the non DR Scap that would stand out for me. I think from your post you are using this on the 252? I really felt that only the DR PS brought out that preampâs potential.
Hope this helps

Agree that DR is simply better. The 250.2 is just bland, bloated and slow compared to the 250DR.
I agree, the black box 250.2 was poor when compared to any other 250 model and to my ears, not a nice sound at all. I would take a CB or Olive box 250 any day in preference. The black Box 250 DR is up with the best of the breed and not just better than a 250.2 but a whole new level.
Had my 20 year old equipment (252/SC/250) serviced and DR-d a couple of years ago. Didnât notice any significant difference on their return (although audio memory is notoriously fickle).
You need to be careful. The DR is a much better amp but (and this is important) it is a totally different amp. Itâs not just a modified 250.2. Same transformer and case. Everything else is completely different and it sounds totally different.
I had the 250.2 with my PMC Twent.23s and it was a great match. They were chosen together. I then went to 250dr and it was a terrible match. I could hear the 250dr was better but it was just thin sounding with those specific speakers and the bass just vanished. Later I upgraded to the Twenty5.23 and balance was fully restored.
So be careful. itâs not a 250 âonly betterâ. Being so different, it may or may not work well with your speakers.
Re the above posts. I think the OP now has a DR 250, no longer the 250.2. He is asking about going back to a non-DR version to âmatchâ the non DR Scap.
If @RichardD could add their current system to their profile it may help to clarify matters?

Iâm not sure I would downgrade/upgrade a power amp to match a power supply. Speakers, sure. The DR variants of the amps (with the exception of the 200) are brand new nearly from the ground up amps. The DR versions of the power supplies arenât. And why you would want less stable DC power to source or preamp is beyond me. There may be a subjective preference to the miniscule amounts of noise present in the non DR SuperCap , but thatâs very much in the same realm as the preference for tube amps with small rectifier caps that leave the faintest 50Hz imprint on the DC output - which contributes to a warm sound. i.e. less good but may prefer it that way.
Worth noting that non DR products do use discrete regulation, just not Naim patented discrete regulation âDRâ circuits.
Get a Supercap DR for the 252 and keep the 250DR.
Or leave it as it is. I would not get the non DR 250.2.
Why did you go Supercap DR to non DR?
Hi i have a TT2 Mscaler . Innuos Pulse and a Moon 260d for digital. Vertere MG1 Rega Aura Audio Technica Art9.
i have had the PMCs for 11 years. They fit my room superbly. However I have always known that if I have added brightness such as Nordost mains it tips it over and makes it a bit in your face.
I had a few years ago the same pre but with the SCDR but non DR 250. I was a nice balance. Tried to live with a big integrated for a couple of years but have come back to Naim.
I didnt think the SCDR was as big a change as the power amp when I previously tried the DR version a few years ago.
I bought the DR on the journey of rebuilding again but in the context of a fast PMC standmount I think I would be better with the bass of the 250.2
My music tastes are mainly metal and 70s rock
