Equipment layout advice

[diviy]

Looking on advice moving my kit to a Ikea lack unit been in the lucky position that my sytem now consits of the following
custom SL1210,Creek evo cd player ,Passive preamp,custom built valve phono stage with seperate power supply ,Recased Time step power supply ,Beresford DAC TC-7510 mk6 with Little Pinkie 12v PSU,Music fidelity X-can headphone amp.

I am also having a pair of valve monoblock being built at present by the same friend who built the following (Passive preamp,custom built valve phono stage with seperate power supply ,Recased Time step power supply) mates rates and favour`s also called in so not much money has changed hands ;);)
The deck is going on the top shelf then the mono blocks underneath the other side of the lack unit will house everything else ,So I looking for advice on Do`s and Dont`s of what to place where items go would it be better to have one shelf for all the seperate power supplies ?
All power leads being swapped from sy cable to cy cable and will be short runs once I`m happy with the placement of all the kit also going to shorten all phono leads as well all leads that cross will be done at a 90 degree`s

Any tip`s,trick`sand pic`s would be much appreciated .

Power supplies as far from kit as possible, one shelf for all sounds a plan.
I wouldn't get too hung up on cable length unless they are crazy long.
If it looks neat it'll probably sound neat too.

What floor do you have (suspended wooden / concrete), and how close is your speaker to your rack?

[diviy]

Concreate floor aand carpet set up is about 7feet away in a 6x8 alcove

Have you a gallery thread Gerald? Some interesting kit you've got there.

In that case I wouldn't really worry.

...I only needed to decouple my system because a) I have a suspended wooden floor that 'sings' and b) one of my speakers is less than 50cm from the HiFi rack. Two areas where you might want to experiment are decoupling your valve amp, and decoupling your turntable i.e. by using Sorbothane.

Try to keep your mono-blocs as far from each other as possible to avoid cross-talk and them affecting each other's performance. Place them close to the speakers, it works wonders too, as it keeps the speaker cables short, allowing them a greater authority on the drive units movements, improved damping factor.

For the same reason you keep distance between source and amplifier I suppose.

Its like naughty kids, split them up and the behave....:eyebrows:

I can understand why, say a phono stage in a plastic case could suffer being near other components, especially considering the signal levels to be amplified. At large signal levels like with power amps (with a grounded case) I struggle more to understand why or how.

[walpurgis]

I keep my monoblocks together. Makes no difference that I can hear. Mind you, I do make sure the 'left' one is to the left and the 'right' one on the right.

[struth]

Although I have mine on each speaker Ive had them together and not noticed much if any difference.

Have you a gallery thread Gerald? Some interesting kit you've got there.

I will be putting up a gallery thread in the next couple of days Jason believes in simples designs built with good quality componants we have sourced parts from all over the world .
the only items we are waiting on is the power supplys that are being custom made in poland uk price is over 1k custom built to his spec £250.00 (daighters have bought them for me as a early crimbo pressie ) delivered within 14 days only job left is build the Ikea lack rack powder coat the end plates I fancy a nice funk purple and also having a lid frame built that will have purple perspex inserted on the top .
I can not put the mono blocks by the speakers mrs put her foot down:( on that I lost that battle but won the war on the rest of the kit ;);)

Mono-bloc amplifiers when placed close to each other on the same shelf can affect each other's performance in an adverse way.

The spurious electromagnetic influences given-off by the power supplies can affect each others performance. Sonically, this can result in a softer, less transparent audio delivery and dynamics can be reduced, together with resolution.

That's the whole point of having mono-blocs, so you can position them right by the speakers and reap the rewards of completely separated channel information in their own chassis and individual power supplies, no left and right bleed-over, you get enhanced stereo imaging, pin-point focus and improved sound-stage.

Each and every time I've separated mono-blocs, all of the above has been observed, and this is with differing brands.

The more air space you provide between electronic components, the more improved the sound.

Probably little difference to most ears. It's not as if it's a pair of 303's we're talking about after all.
With all of these small tweaks we should remember that most people who can afford pricey kit like monoblocks etc are of an age where their hearing is on the wane.

[Macca]

I'm a little skeptikal of the idea that seperating monoblocks improves stereo seperation.

I always thought the reason for monoblocks was portability. So you could use big traffos and heatsinks but it would still be liftable. Unlike a dual mono amp of the same design. I know you can get dinky little monoblocks now but I can't see thr point of that unless it is just easier to make them that way.

Sounds unlikely to me. What research is this observation based upon?

Listening & hearing the benefits.

[Yomanze]

I have noticed that moving furniture around, plants, TV positioning etc. changes the sound, so stands to reason that the same would happen when moving two honking monoblocks around.

Make sure you keep your tube gear a good few feet apart from your wireless modem.
I moved some gear into a new rack a couple of months back and without thinking positioned it close to my hub.

The modem induced a awful low pitched thrum into my tube pre, took me quite a while to trace my error.
