I've just bought a balanced transformer!

I use one for the Vida and the Truth but wouldn't for power amps. My amps are wired direct to their own 30amp spur.

You can see the inline filter built into the back of the IEC inlet. There's also a transient suppressor of some sort (the black disc thing).

And the blue disc-shaped item near the IEC inlet filter might be a VDR.

Mark, just had a flick through this thread with great interest. I own a P10 regenerator, granted, not the same thing but dosen't a decent power supply to your kit sound great!

Indeed - a decent supply is the foundation to any system sounding at its best. I used to have a PS Audio P5, and I have a distinct feeling that one of these BMUs brings far more to the party in terms of beautiful sound and musicality, at a tiny fraction of the cost (and box size, for that matter). Add to that, unlike a P5/P10 a BMU consumes hardly any extra electricity, and there is very little (eg pretty much nothing) to go wrong

Yes, as Hugo says, there is nothing really to age or go wrong.

Andy, yes, it is most beneficial . However, as you also point out, fundamentally different to the approach taken with your PS Audio unit.

-------------
In the picture above, of my unit, you can clearly see the large NTC (the black disc component on top of the transformer) used to limit inrush current when the unit is first turned on. last night I tried removing it from the circuit (very easy to do). Unfortunately I quickly found out that the inrush current of a 3000VA transformer is more than sufficient to trip the circuit breaker on my main fuse box! So, after a quick visit to the cellar to reset the fuse box I reinstalled the component and calm was restored - no harm done .

So would these additions have any effect on sq ?

I think so, particularly the inline IEC filter. I wouldn’t advocate pulling your BPS apart yourself to replace the inline filter with a plain IEC connector though - if you feel like experimenting with removing the filter components, such work should only be done by a competent (in the electrical safety sense) person.

See Mark’s post above regarding the black disc component, which is needed to limit initial current rush when the unit is switched on.

I used to be an M & E service engineer working on control panels and equipment up to 415v,so swapping the IEC shouldn't pose a problem.

Get rid of the IEC filter, but don’t worry about the MOV disc, I would keep that there...
