I have to say, back when I had my Olive series, I experimented with pretty much every possible placement - left, right, above, and below. The only arrangement that sounded ever so slightly worse was having the HiCap, NAT02, and later the NAPST positioned to the right of the preamp (first the 72, later the 62), presumably because of their proximity to the phono boards.
That’s not really an issue with the 52, though. So in your case, I’d simply go with whatever setup makes the most sense from a practical point of view - whichever arrangement gives you the easiest operation and the cleanest cable routing.
Ideally as Igel pointed out you’d keep the 135’s two levels away from the 52 but if you only have two four level racks it’s about the least worst option . LP12 and CDS needs tip tier positioning and Burndy dressing has to be factored in doesn’t it? Happy listening
Thanks for the great suggestions, Cohen, Igel and Loki!
In the end I put the NDX2 under the 52 head unit as a known compromise, but we seldom use it and 95% in deep sleep mode so everything is fine most of time. A tad brighter when using though, probably due to interference.
The rest are all good and very enjoyable, will re-arrange according to all your suggestions next month.
Just an update of the rack arrangement (and thanks for all of your help! much appreciated)
I put the 2 psu (52ps & cdps) at the bottom now, with 135s sit between the cds head unit (top of brawn rack) and cdps (bottom of brawn rack).
my ndx 2 is always in deep sleep mode so I put it underneath 52 head unit – the only compromise here. But we don’t need top notch sound when listening to streaming anyway.
Such rearrangement resulted in much better nuance and dynamic. I don’t need any warm-up to get the warm, full and meaty sound at all! Really look forward to how it would go after 5 days…
Playing Paul Chamber’s ‘Charmer’s Music’ in SHM-CD format, full, fat and warm, perfect prat!
Did’n’t know arrangement of power amps is so important, I thought it works like PSUs…
