Sorted out my power distribution now. Significantly tidier with a lot less in the way of extension leads.
Powercon connectors are superbly made, wish they were used more.
Main breaker unit powers almost all of the hifi and my pc. Only the hardwired plugs remain for the pvr, dvd and bluray players, which go into the 6 way 13A block.
The two way socket is used in addition to the 6 way block for my external devices. (phantom psu, hdd psu and chargers)
The main bulk of wiring that goes to my desk now goes up the leg instead of spaghetti across the wall.
I also dismantled my newly acquired tannoy studio monitors to check the condition of the crossovers. I took the opportunity to give the cabinets a good clean and wax/polish.
One 10" monitor gold woofer/tweeter assembly.
All reassembled in a very clean walnut cabinet.

Those speakers are bootiful 
Does all the wiring not cause some kind of interference / feedback / signal noise back there?
[pre-derail-warning]
Edit:Speaking of which, quick question. My dad's got a 7.1 receiver wired up to a nice KEF 7.1 setup. The Subwoofer 'hums' when it's on and powered. I've narrowed this down to some kind of noise coming through on the 230v socket it's plugged into. It's coming from the receiver itself. This thing has been sent back twice and the shop doesn't get the same result when they test it, so it's not the receiver (hopefully).
The house has v.old wiring and there isn't another usable socket within a suitable distance to re-route power.. Is there anything available to put between said A/V setup and the socket to clean this up/remove it?
He's had a sparky in (who didn't seem to conceptualise the issue properly and thought it was an earthing problem) and he 'tested' the outlet and apparently it's fine. He didn't understand what I meant by noise, and it's all earthed fine...
Any suggestions mate? (Sorry to derail, but seeing all that gear, just makes me think you'll know
)

Cheers, good to see some people appreciate quality vintage gear.:wink1:Those speakers are bootiful

Nope, no interference from anything. The sign of a good amp is decent noise rejection. Coax signal cables may help a bit too
Do you know if the noise is coming from the transformer on the sub amp or is it being amplified through the woofer? If it comes from the woofer, does it still happen if you unplug the input from the receiver?[pre-derail-warning]

Noise wise, i'm assuming it a low frequency hum? (50Hz hum, rather than high pitched interference)

Newly acquired iiyama PLH540S 21" panel matches the dell 24" perfectly especially now that i have 1920x1080 + 1600x1200. (the cursor used to jump slightly as the vertical resolution on the AG Neovo panel was 1280x1024) Really need to get a colour calibration tool as getting the colours to match across both panels is very difficult. (dell favours greens/blues, iiyama is more red/yellow) I doubt it helps that the dell is an s-pva panel and the iiyama is (AFAIK) an ips.

Probably worth trying out an isolation transformer between the sub and the amp. (in-line with the signal cable) A quick and dirty test to see if that would fix it is usually to pull the earthing connection on the sub/amp. (if there is one) But obviously that's not without it's safety risks and certainly not a good idea longer term.

All that audio gear, OMG my wet dream xD

The obsession gets worse. Collected some more speakers and amps on friday. No idea what i'm going to do with them as i can't use them all at once. I'll end with one for each day of the week if i don't stop collecting stuff. I'm starting to have a hard time deciding which i like the sound of most too.

Having spent some time listening to the Spendor's, I've decided that whilst they do sound excellent, they are outclassed by the Tannoy super reds. My room is a major mountain of cables and audio kit at present due to the massive amount of changes I'm making. It'll soon be at a point where i could probably run my own recording studio if I'm not careful.
Headphones have also gotten out of hand too.

Thorens turntable and Tannoy super red monitors. Nice. Very nice indeed.
Also digging the car seat hack. Sweet room.

Since my new parts arrived this morning, i got on with replacing the capacitors in the R300 power amp. (upgrading from Capxon chinese caps that had certainly outlived their expected life)
Nice modular design means that i can take one channel out at a time. PSU is also separate too.
One amp channel part way through.
Channel complete. Notice the huge difference in size. I used bipolars in place of polarised originals for the audio path as it significantly reduces distortion. (something only auzentech did on their soundcards. Fine golds are not as good)
PSU half way. The replacement CDE caps are physically the same size yet are 18,000uF and have more than twice the ripple current. Inrush currents are going to be fun with these, plus some additional strain on the bridge rectifier.

Love what you've done with the selves, really tidy looking and seems like it wouldn't be too hard to put together. i had never thought of replacing out the speakers from an old enclosure. I have a pair of awful sounding speakers that I might try and refurbish, might be a nice way to learn a bit about how they are made.

After 12 years I've finally replaced my AV receiver with an AV pre/pro unit. It is definitely more substantial than the old SR4200, problem is even though it is quite shallow for a modern AV unit, it's still a tad deep to allow adequate room for plugs once the rack is pushed back towards the wall. The good news is that it freed up a shelf as the luxman integrated amp and the sonnifex balancing converter were no longer needed. If my xonar essence st is still causing ground loop headaches after this point, i'll be using optical only now i have a free port.
