Amp orientation - a question about the 250

Posted by: Top Cat on 14 January 2004

Hi folks.

My 250 has a habit of buzzing especially when some rather less well-behaved electrical things are on elsewhere in the house (and as it happens on different spurs and CU).

I will work at minimising this buzz, but at the same time I am thinking about positioning the power amp in a cupboard, so that it can buzz all it likes but it won't be heard. The other benefit to doing this is that the same cupboard houses the dedicated consumer unit, so all I'd need is a tiny spur to effectively hardwire the 250 with 10mm.sq. cable.

To fit the amp in this cupboard, it will need to stand on its end, and I'm thinking about making a kind of bracket into which it can be mounted, so that the front of the amp is at the top and the rear is just a couple of inches off the ground, with speaker cables going directly under the floor and the spur taking a very direct route into the amp. This depends on the length of the preamp output cable, but assuming that this is long enough, is there any reason why a Naim amp shouldn't be operated in a vertical fashion?

I think this would make for a really neat solution to the buzzing problem and makes the use of a dedicated hardwired spur even easier. However, if it's a truly daft idea, let me know why...

Thanks,

John

you can flip your NAP250 anyway you want, it makes no difference to the sound. You may want to ask Naim Audio to supply you with those rubber isolations that used to isolate the amp and somehow glue them on the side of the case. Vertical position will facilitate the heat dissipation better than the normal position.
