POWER GAMES:Servo Stabilizer,CVT or Online UPS?

Hi Ajay 124

Yes 1.5 KVA is what you will need. I have had it for a year. Absolutely no problems. Its hard wired so cannot remove and compare. But IMO cleans up rf/emi without any negative effects. Also protects against spikes. Needs to be switched off when not in use. Also heats up hence needs decent ventilation

I have dedicated wiring from the meter box for the audio set up. I use 12 gauge Romex wire which has been cryo treated. Also the quality of outlets makes a huge difference. I use Oyaide outlets with their carbon fiber wall plate. Makes a big difference. Hubbell 5362 all brass is also very good. Since i have a US receptacle, all my connectors are US connectors. Here i would recommend either the Oyaide or the IEGo all copper or the Yarbo all copper. My powercables have Yarbo all copper connectors.

To add to my above post i also prefer solid core copper power cables to stranded copper power cables.

Whle the best solution is an APS Purepower regenerator from all sources I could find.. it is far too expensive for me to consider at this momment ( try going through this thread !!

there is another factor to this- any SMPS source further pollutes the power..hence its very important to have your CD/DAC to be completely isolated from your analogue amp/preamp as well.

sir, it is ironical that the above two sentences come together. most power regenerators work like SMPSs.

room conditioning. or better still, (nearest to possible and practical) sound-proofing. ........best BOTH!!!

..Sound proofing is not the issue..i have discounted that..power is !

sir, it is ironical that the above two sentences come together. most power regenerators work like SMPSs.

Maybe, but the SMPS for the CD source will pollute the power tothe rest of the componenets as well, unless they are filtered.
SMPS from the regenerator may poluute the rest of the house but not the audio equipment right ?..not sure if i missed your point

Hi Ajay 124

Once you have a CVT your equipment is protected and sound quality is same all through the day. Now to improve the quality of power you need to further reduce rf/emi/ground noise. You can do this by placing crushed amethyst crystals in a plastic packet in the circuit box. Place one under the MCB. You will immediately hear an improvement. If not amethyst try normal quartz. This is a cheap effective way to clean up power. Its the principle on which Acoustic Revive designs its products. I have found amethyst to be more effective than costly power cleaning solutions

prem, this is a fantastic suggestion. any idea where to get these crystals ? (And how to crush them !!)

Should a good conditioner NOT completely eliminate RFI/EMI? Why would there be a need for further processing? Methinks if the conditioner does not eliminate RFI/EMI, it is not doing it's job properly.

there can be no absolutes ('eliminate' being a superlative). there can only be a point of diminishing returns.

are you speaking of EMPs or an SMPS? a regenerator works similar to an SMPS, so has its inherent drawbacks. these pass on to all the equipment powered by it.

Behind my audio rack is a window and beyond that a veranda with a 5 amp power socket which is also connected to a Sukam inverter.If I connect the CVT to this point in the veranda what is the best option for connecting the CVT to the cdp,pre,power.Ideally I would prefer the shortest,simplest,preferably a direct connection to the CVT.Using an extension board with multiple sockets does not appeal to me and would be the last option.Distance from CVT to audio rack would be 2 meters.
To protect CVT from rain/dust/theft I would need to house it in an iron mesh/box.How much ventilation would it require?Can it be left permanently powered on?

Dont make the mistake of connecting a CVT to a 5amp socket with power consumption more than 5amp.

Are you including an inverter to the chain?

Hi Venkatcr/Arj


The amethyst kills a lot of airborne rf/emf. At the circuit box it cleans up the power before it goes to the CVT. This seems to help. See if it works in your set up. It costs only Rs 300-400. One way Arj could be that you can go to a fashion jewellery store specialising in stone jewellery and ask him for an amethyst bangle/chain made up of small amethyst beads. Remove the beads from the chain and break them into smaller pieces. You can use a normal hammer for it. You can also keep amethyst crystals near the system, either under the rack or behind it. It will kill airborne emf/rf which no conditioner can address.

All acoustic revive products seem to be designed using the piezo electric effect of the crystals.

You can also try a small tourmaline crystal on top of the cd player exactly above the pick up lens. Tourmaline releases negative ions which reduce static electricity thereby making sound more organic. Acoustic Revive negative ion regenerator i think works on the same principle. Again try it out. Will set you back by about Rs 200.

i have taken a direct line from my residence building main DP upto the input taps of the CVT (soldered on), via an MCB that i use as an on/off switch. i then have taken three lines directly soldered to the o/p taps of the CVT to the audio rack (in my case the distance from the DP to the CVT and the distance from the CVT to audio rack are sizeable), to power my speakers, amps, sources, etc. the speakers and amps have a dedicated line each. the sources share a line (one at a time, when in use). i was able to get a specialised finolex cable not available easily in the open market for all this.

good ventilation (possible and helped on with a dedicated, small [computer blower kind] fan) for the CVT is suggested.

i would not suggest a permanent power-on. will reduce the actually used life of the CVT and also mean an increased power bill to you, tho' you would not have been listening to your system for most of that time.

i would suggest a 15amp source for the CVT (esp. since considering a 1500W), if an option. i would try and avoid plugs and sockets to the extent possible. direct soldering is much better, esp. if long term. also, an MCB is a better option to a place where you need to turn on or off a power source. reduces the possible issue owing to a loose (or bad metal quality) plug/socket mating.

If I do buy a CVT I will confirm from the manufacturer whether
I can use a 5 amp socket and whether I can keep the inverter in the chain.
The CVT option is seeming to be a good one.Would take care of eveything:
Protection from Surges and Spikes
Regulated,uniform power
Isolation and filteration of noise
No recurring cost or maintenance
Second option seems to be an online UPS.Isolation will not be very effective
but will provide back up.
Most of the professional's in the field of power conditioning have suggested
these two options and have advised that a Servo Stabilizer
with moving parts and mechanical operation's should not be considered.

 

[Thad E Ginathom]

Isn't the isolation given by an online dual-conversion UPS pretty-much complete, in that the power is being permanently drawn from the batteries?

I can consider advice from an astrologer that the placing of a particular crystal might affect my life, but I can't accept that it is going to do anything to my hifi. Sorry: I am just too cynical.

if the CVT is correctly rated at 1500W, it will come default with a 15 amp plug.

and whether I can keep the inverter in the chain.

if you mean between the CVT and your equipment, not a good idea. will defeat the advantage the CVT brings.

you MAY be missing 'a naturally outputted pure sine wave'.

@hifiashok
The inverter is near the main circuit board and would be before the CVT.But if I need a 15 amp power socket then anyway these are not connected to the inverter.Since I don't want to run the system on an Inverter,that's o.k.I was trying to fix a location in the veranda for the CVT which is close to a 5 amp socket.The 15 amp socket is further away but I guess that would be the correct option.
The naturally outputted pure sine wave that you refer to.Is that from an Online UPS or from a CVT?Not very clear from the post.
@thad
The dealers of online UPS's have specifically told me that if Isolation is required,then an Isolation Transformer costing between 7-9 K will be extra.Maybe the double conversion gives elementary isolation but it cannot achieve the same level as an Isolation Transformer or a CVT.

 

[hifiashok]

only differential power is drawn from the batteries, unless there is no power. and the situation we are wary of is not when on batteries only but when on power. so, no.

if you don't mind my submitting u MAY need to read up. one easy to understand concept is Desiccant - Wikipedia, the free encyclopedia. as a matter of fact, the amethyst option is subject to empirical evaluation whereas the astrologer option is not!! i too am not easily convinced about things/claims, on whichever subject, even non audio. but, am convinced if suitable empirical and statistical inputs are available. i must say a lot of my earlier beliefs have slowly been busted as myths, and i now am much more open minded.

is mentioned after the CVT pros you have enumerated to add on what was missing, so CVT. apologies.
