    More power to my Naim

    When I have an active system driving SBLs, and contrary to some above, I found the SC on a SNAXO to be a worthwhile improvement. That said, and without direct experience, an XPS (or Teddy equivalent) on the 272 would seem to be the logical next step.

    Mark I Kans + Uniti Nova = I fried my woofers and/or xover?

    From the OP, the serial number is 039xx not 39xxx so he will need a B110A (SP1003) rather than B110B

    Avondale DIY upgrades for Naim NAP 180 and 250

    You might well be right - the NCCs already have filtering and diode isolation from the main power supply so a separate one might not add that much more. For the NAPAs which don't, I found it had a large impact.

    Avondale DIY upgrades for Naim NAP 180 and 250

    All 180s are the same as far as I'm aware. The older pictures may be of 160s? The PSU board is the same as in the 140 but as 140 only has one winding on the transformer, the tracks going to the rectifiers are joined where the transformer cable attaches to the board.

    Avondale DIY upgrades for Naim NAP 180 and 250

    The above gives a good overview but there are a couple of points that should be clarified. Actually, in the 180, each NAPA board has its own supply. The 180 transformer has two sets of output windings feeding two pairs of reservoir capacitors, one for each NAPA (the preamp supply is separately...

    Climate change teaching in schools

    Again you're quibbling about details as if the government are ever going to implement this. The engagement I was talking about is things like petitioning the government for change. And I know it's like banging your head against a wall but if it gets above a certain level, it has to be raised in...

    Climate change teaching in schools

    While agreeing with some of the caveats mentioned above, I think this should be wholeheartedy encouraged. People are quibbling about the minutiae of implementation when the important thing is getting young people engaged in trying to do something in the face of a government who are basically...

    NAIM Hicap LED light board replacement - Advice needed

    I also have a chrome bumper Hicap that was converted to Olive by Naim. I bought it like that but was told that installation of the olive era logo backlight wasn’t part of the conversion. i.e. they changed the front panel and switch knob but the single CB led was left in place (though you can’t...

    Tory Leadership Runners and Riders

    I'm not the original poster but it's a pity that had to be deleted as it was indeed quite powerful. It was from the comments section on the article rather than from the Guardian article itself - does that make a difference? Anyway, here's a link for those of you that want to read it and thanks...

    Naim power amp wire - board terminals/connectors

    I've just checked on my old 140 and they are labelled 22pF. Avon posted whilst I was checking this so this is just an update as to their value. The 180 has a weirder arrangement than the 140 with no actual connection made between the front board "ground" cable and the PSU ground. They are...

    Naim power amp wire - board terminals/connectors

    On the later psu boards, the green wires from the front of the board only connect to ground via small value capacitors on the psu board. I think I read somewhere that on models like yours, the capacitors are under the black heat shrink at the psu end of the green cables. If true, it would...

    Upgrading Yamaha NS-1000Ms

    The bass low pass is now 3rd order as opposed to 2nd order on the original. Troels shows some measurements showing the third order one tracks LR4 much better. He also put a notch in the tweeter to smooth out a bump. There may be other tweeks as well but you can't get the values without buying...

    LED Red to Green CB Hi Cap

    It's worth bearing in mind that in the Hicap, the voltage for the LED is derived from the -ve terminal of one of the bridge rectifiers so the driving voltage is negative wrt Ov. In this particular case that means the anode goes towards the 0v line and the cathode goes towards the rectifier...
