From supernait1 hicap to 282 250.2

With the Naim boxes sitting directly on top in a pile you may as well keep the sn1, the higher up the range you go the more important setup is. The music can get lost if its not right, In my case a target rack was replaced by Fraim lite to great benefit when I had CDX2/282/hi/250-2 and pay attention to cable dressing and even plug order if using a block, you are using NACA 5 I presume. If you’re using internet over mains, don’t and no power conditioners either.

Thanks,the speaker cables and power cables is naim’s,I have a hiline on nat05sx and  the 282,250.2 have on rack alone.

Sorry. It’s a power line on nat05sx.

My source is ndx , it’s said 282 and 250.2 is another level. 

I donot feel the big difference.

is there something wrong?

I'm not surprised,  the Supernait is a pretty good amp,  IMO the best integrated that Naim have ever made & it was not bettered by its wam bam thank you mam cost reduced SN2 successor.    The Supernait is an active line-level preamp & its circuit design is reported to be derived from the NAC-552.   So on that basis the pre-amp section is going to be hard to beat.    The 250.2 however is something else & I am sure will outperform the power section of the Supernait by some margin, but you probably won't hear that unless the volume is up very high or your speakers are a difficult load,  which I don't believe the PCM OB1i are.    

What do you mean by "cost reduced  sn2"compared to sn1?

The obvious ............  no internal DAC meaning no multiple digital inputs,  no buffered tape/record selection bank
