I bought a naim nac 252 preloved, sound is very fantastic but I have a big problem with volume, at 9 o clock the volume is too high, also for e example with mfsl cd. which are recorded very low, I have focal diablo utopia (89 db) and nap 250 dr, with my old 282 with the same supercap that I use with the 252 I didn’t have these problems.
With the volume knob at the lowest setting is that about 7 o’clock?

Yes I removed volume knob to check and is aligned with pot at zero
This is pretty common, though a bit dependent on the recording if streaming.
I found that I didn’t have to turn the volume up as much with 252/300DR for it to fill the room. It sounded better, more in control etc at increased volume too, compared to 252/250DR so I’m happier anyway.
I do wonder perhaps if my 250DR wasn’t fully burned in, but the 300DR…hoo boy…
In my opinion is a defect, is not normal that at 9 o clock it seems to stay in a discoteque. Sound is welfare but too high, too much difference with 282
Could you not just turn it down to a comfortable level?

What was the volume knob position with the 282?
What’s the room size and listening distance?
How many dB are we talking at 9 o’ clock (a rough measurement with a phone app will give us at least an idea)
When you dial it down from “too high” at 9 o’ clock, how far down do you go?

A usable volume control range over just a very small part of the ‘dial’ is not user-friendly. It strikes me that what is needed is a gain control on the inputs - some amp manufacturers provide such a facility (e.g. my Radford integrated back in the 1980s): perhaps ot is something for Naim to consider implementing….

I just use the remote to adjust the volume, it’s easy to do and the Narcom 5 has a fine adjustment. I can’t see the volume knob from my listening position anyway so I don’t get hung up on it.
If 9 o’clock is to loud just turn it down. If the gas fire is burning my feet I turn the fire down!

We talk about a room of 40 mq and at 9 o clock, i have misured 91 dba, at 8 o clock the volume is acceptable but high.
Thanks. Based on the values it doesn’t seem to be out of the ordinary. It is a similar size to my room, my speakers are a little less sensitive (86 dB), and on my phone I also measure about 85-90 dB at 9 o’ clock, with 252/300 and the line input. Personally I don’t find this too loud at 9.
I use anything between 8 and 10 o’ clock, depending. Nor would I say that 8 is “acceptable but high”, for me it’s low-ish without being much too low.
Based on the values being similar to mine I’d be inclined to say that you simply prefer a little less lower volume than I do, and that nothing is wrong with the equipment. However, your different experience with the 282 is strange. Did you use the same source(s) with the 282?

Thanks to you, Same speakers, amplifier, cable and Source.
Weird. And the same volume that you have at 9 with the 252 was at which position with the 282?
With my 552/500 in huge room I never go past 9:00 using streamer ndx2/500ps
Mostly 7:30 volume or 8:00
Without knowing speaker sensitivity it’s meaningless
91dB
I thought speaker rating was 89db?
91 was a measurement I think.
I meant davidf’s
I know. Titan T88s are 91dB sensitivity.
