Placement (amps, psu, pre amp etc)

[NSNO2021]

My ears have told me in no uncertain terms to give my kit some breathing space. Right now the A80s, PSUs, P70, Tom Evans Micro Groove Plus, Lehmann Black Cube & Meridian 204 are loosely spread across my floor whilst I figure out how best to store them. The system already sounds a lot better for being "de-racked".
Is there such thing as an optimal component placement/arrangement. For example is better to keep the A80s or the PSUs apart and I know my P70 is sensitive to electrical interference so I do my best to keep that away from the A80s, PSUs, WiFi router etc. Any thoughts or advice welcome, thanks Paul

As much distance as you can sensibly manage. This thread from the archive should be helpful: viewtopic.php?f=29&t=48816&p=162390&hil ... nt#p162390

Thanks for the link Paul

A long wide wallshelf might be a good solution, with holes drilled or cut out at the rear for cable routing. With book, CD's, possibly vinyl etc filling in the gaps between components.

I use my late grandmother's coffee table and a Sound Organisation table for my amplification bits for my upstairs system.

Plonked on the floor is fine from a sonic point of view, but likely to be a trip hazard for health and safety.

I still stand by anything i said in that thread.

Getting the phono amp close to the arm lead out is something i am to experiment with. Naim put the prefix inside the L12 to reduce the length of wire from cart to phone stage to a minimum. It was shielded in a metal case of course unlike nva designs. The psu for it (hicap etc) was in another case that could be sited well away. Of course a nva phono board inside a deck would pick up all sorts of interference from the record players psu and motor unless in a metal case.

My plan is to make a metal case for a nva phono amp pcb along with regulators and a pair of smoothing caps. Put that right behind the record player, have a very short arm lead and make sure the record player has an offboard, remote psu. If it has an onboard psu then offboard it. Also dc motors are said to give off less crap than AC ones. The rest of the phono amp psu (transformers, rectifiers, first smoothing caps) can be put in a separate case well away from the amp board.

Sounds like a good plan Stu!
Wanted to ask for photos of your project but then I remembered some of you Frankenstein creations and I am not so sure anymore ;]]]]
But very interested in you findings

Hahaha. Yes it will be agricultural looking at first . If the concept works then i will build something more aesthetically pleasing. Eventually. .................

Well if you ask me it do not have to be more aesthetically pleasing - as long as you happy with how it sounds and as long as I do not have to see the photos ;]]]]] not that I do mind it just give me nightmares...

If I can't and I am reasonably sure I can't get my phono and pre amp more than 2' foot away from the A80s and PSUs is there anything I can use to screen them ? Thanks Paul

2 feet away is not a bad distance away. What size transformers are in your non nva kit ? Your A80's have 160VA transformers in i believe.
