Mains power and conditioning

[Pjotr27]

I got a little reaction from Devialet, buy an APS.... but which one, how much wattage? It is nog so easy...
You also have regenerators, is that also an option?

I bought a Torus RM 16 earlier this year and it's making a huge difference. I can very much recommend you to try one at home to see for yourself. You will be surprised... :-)

I have just found a read through this thread.
Being a retired electrical engineer i've had some experiences with the quality of electrical mains. Having measured the effects of noise transmitted into the mains caused by inverter motor controllers, dc rectification, simple thyristor controls in lighting system, they all make a noise.(back ground hash).
Also i've been lucky to have used some very good types of filters etc.
Now for myself i've done as we did most of the time, i installed a 5Kw balanced transformer, fed from a 30amp mcb via
10mm swa cable, the outputs are unswitched metal clad sockets all protected by rcd and double pole mcb's, the output are wire with Furutech cable.
The improvements are vast, all back ground hash is gone,sound stage deeper and wide bass now deep,i could go on.
If you have the money along with an understanding electrician, preferable one who have a heavy industrial electrical background, give it a try, you will be impressed

Sounds interesting.  It would be good if you can generate a parts list for us laymen to refer to?

 + 1.

And balanced transformer = isolated transformer, right?

Tks!

Hello all,

I have experienced a loss of dynamics with certain power distributors when connecting amplifiers with switch mode power supplies. It seems to me that the power distributors are restraining the flow of current not being "fast" enough.

Best regards
BjornWiman

I think "a loss of dynamics" sums up very nicely what I remember hearing.  So what we need is something that can clear up any mains issues, without invoking any power / current restrictions that take anything away in terms of dynamics or anything else.  Any ideas out there as to what might do the job?

Hi Confused

Late in the thread. Perhaps someone here has tried Lab12 Gordian power distributor/conditioner? It's written that the item doesn't affect the dynamics of the system.

Hello, I have long experimented with power supplies. Now use IsoTek Evo3 Sigmas only for the source devices (Melco, Linn Klimax DS ....). Expert 220pro is directly on the net, without filtering. Play now to my fullest satisfaction

Has anyone tried out hamster wheels?

[K4680]

Everything already tested, unfortunately the hamster no longer wanted
