552/552PS just in my system. Cold. Using the DAC in my 272 for now. But I mean, come on. WHAT KIND OF PRODUCT IS THIS? I’m speechless. Emotional as in crying. Empty on words. Wow, just wow. It never ends does it. I love this drug.

When I had the 52, I never felt the need to consider a 252. I just assumed it would be an expensive sideways step.
But the demonstration 552dr did not leave when it came her. Much better (I think I had a single 300 into SL2 speakers at this point, although I might have been active with 2x300dr by then. Have forgotten the order I did things…)

The 552DR is the best upgrade I’ve done by quite a large margin, enjoy!

Sweet. I wonder what you’ll say when you get an NDS or ND555 as source? I find the NDS ridiculously good.

DAVE / HMS (caps lock on) connected to my 552DR, phenomenal sound
Ever compared NDS with NDX2? I’m running against the NDX2 due to being latest platform. I felt locked in with the old but I’ve heard so much great about NDS.
Sorry, never heard the NDX2. It just might give the NDS a run for it’s money with equal power supply.
Don’t sell it. I think it will only appreciate in value. It’s a piece of art and Naim history. I really regret selling mine, even if though it’s been replaced by a new 552DR.

Perhaps you’re right as the 500DR brings so much more performance out of the 552DR. But I have a 552 DR paired with NAP135s and I don’t think I’ll ever change this setup. It’s so so bleeding good.
I couldn’t agree more. The only thing to mention is the noise floor, which is higher in the older gear. But in exchange you get this flow and engagement to the sound.

Noise floor in 552 is pretty high.
I was using NAC52 with 2 x NAP135. As I had only recently had the NAP135s serviced, I chose, perhaps unwisely, to change the NAC52 for a NAC552 before changing the NAP135s for NAP500. I found that change to be nothing particularly remarkable. It was only when I swapped to the NAP500 that everything became so much more realistic, with greater presence and authority. Perhaps if I’d changed the power amp first, I might have retained the NAC52 for a while longer. C’est la vie.

Wasn’t the Nap500 developed with the Nac52?

Yup. But…but… but… its not the latest… So its rubbish… 
(My whole system is rubbish… hardly anything current… 
Surprising it works at all…)

Fair enough. Although in my setup, I clearly notice the difference between the 52 and 552DR when paired with the NAP 135s. I have no desire to change as it’s stupid good now and i’ve learned my lesson- when a system sounds this good. Leave it alone.

My newly bought 552 is a total game changer to me. It’s like from another planet. I was prepared for a lot but not this. I’m in love 
Tomorrow NDX2 enters with a Hiline. Yummi!
