The concern Bryston had with a lot of power line conditioners available in the market was that many of them could restrict the current available to the amplifier. An amplifier can draw very high peak current, and wants to 'see' a very low impedance high current source from the power line. In fact, we even stated in our owners manuals not to plug our amplifiers into power conditioners. The Transformer based line conditioners we tested were too small to supply the peak current required and many of them were just Filters and did not provide Isolation -(Isolation means there is no mechanical connection between the outside power grid and your inside system power supply).

Also most of the surge protection was done using MOV’s, which are sacrificial and eventually will be destroyed with repeated spikes. Other issues with these MOVs is that they allow much more voltage through before they reacted (typically 300 volts and higher) and they shunt the voltage spikes to ground.

So we decided to try and develop a powerline Conditioner, Isolation and Protection unit that would not have the restrictions of the many units currently on the market from an amplifier performance perspective.

Yah but napamax says.... "An amplifier with a properly designed internal power regulation should not need any external band-aid booster."

Hi there;

   I am a very happy new owner of a Torus CS20. I when with the CS20 on the recommendation of my Dealer who said he did extensive listening tests between the CS15 and the CS20. He found that the CS20 just seem to give a moderate system that "ease" where the music just flowed effortlessly compared to the CS15. I took his word.
   My system consists of a Linn Klimax DS digital stream player, a McIntosh C500t tube preamp, two McIntosh MC501 mono blocks. This feeds my PMC IB2i's. I also have an Anthem D2v as the processor, plus a few other amps and things plugged into the Torus for surround sound.
   As far as what the Torus CS20 did to my 2 channel  system is phenomenal!! I thought it sounded great before (Had a Monster 5100 conditioner) but now everything just flows. Very deep sound stage, Instruments and voices are just so real. Bass is tight with more punch, mid-range is smooth, and the top end sparkles. The PMC IB2i's are non existent!
   Overall well worth the money. I love it!

From what i have observed from people's comments and my own personal experience with the rm20. I would say that there is a difference in the 120 to 240 volt models also. My system has so much more jam now its impossible to miss. Then i read 120v versions and i get this so-so feeling for upgrades from the comments. The 240 lights my system right up and i know its the same on Drummermitchell's also.

Thanks for quick post James.
The only reason I asked this was for I did want to try the amp with conditioner first day when I un packed the amp but after reading the manual I never did it.Now the only way I would pay for the torus would be if I can try it before buy it because in my tri amp active set up I never push the amps hard even in high volume and still I am not sure that I would need the conditioner or not.
Could I ask that what would be your idea on this?
Thanks

Can someone in laymans terms explain the advantage of 240v over the 120v?

Hi - sorry which amplifiers are you currently using 7B's and 4B's?

Don't know actually but i am beginning to think there is a big diff between the 120 and 240 versions.

                                      That's a good way to describe it ,
                                      The first bike don't look like no Honda 50.

Its a forced dedicated line into your Torus. There will not be any thing else on that 240 20 amp line. I went from a 120 15 amp line that had other outlets and things running off that circuit.

The Torus uses 2 - 120v 10 amp lines from your fusebox where a 120v uses a single 120 15amp service from your fuse box. The 240v feeds more power into your Torus right up front.

It also use a balanced cable from the wall into your Torus. For those that are into power cables the balanced cable is ideal for noise reduction. IOW an aftermarket power cable is not so crucial considering also that the provided cable fits really tight into the Torus.

Its also uses a balanced line in from your fusebox resisting noise into your Torus.


The ONLY drawback is you can't plug into just anywhere so you lose mobility with it. Moving your system to a different house or room can be complicated. You need that 240 in line..... so thats the only drawback.

[konut]

Maybe not the only drawbacks. Correct me if I'm wrong, but isn't the 240V Torus over 100lbs? My back can't take that anymore. Also, its north of $3000. My wallet could never take that. 

[drummermitchell]

Depends which Torus,a 20a bal is 75-80lbs,
a 60a bal is 155lbs,I have them both and they are nasty(good that is).
3000 is a bit o coin alright,depends, just like components how much do you want to get out of your system.
I want all I can,if I can afford it,especially when you hear the improvement.
That's why I do home auditions(free)if it isn't an obvious sound improvement I won't buy it.
Torus is the real deal,weight and all.

[werd]

120 v - 96lbs
240 v - 89lbs

The 240v is lighter in the rm20.

[drummermitchell]

what's a few extra [pounds.

Hi James
I am using total of 4 amps right now 2 4B SST and a pair of 7B SST at same time in active system.
Thanks,

Use common sense and the fact that "napamax" is not trying to sell you anything.

(Isolation means there is no mechanical connection between the outside power grid and your inside system power supply).

"mechanical", James?  do you mean that in a Torus, the secondary coil of the transformer floats in void without touching anything?

No I mean that there is a magnetic field between the primary side of the transformer and the secondary - so the primary side has no mechanical connection with the secondary

Hi PRELUDE,

If the 7B's (or 14B's or 28B's) are the newer versions then NO Torus is required. The Torus, as far as an amplifier is concerned, is more important as the size of the amplifier increases and the difficulty of delivering transients to the loudspeaker from the amplifier.

So unless you want the isolation and protection that the Torus also supplies you may not need the Torus (BIT) in your system.

Correct me if I am wrong, It should not make any difference whether the unit is 240v primary or 120v primary other than perhaps the incoming current & wire size. The Isolated secondary is the same on both Torus units CS20 balanced vs CS20.
