AC power regenerator for ESL bias supply

71.191.81.92

I had a low power PS Audio regenerator that needed something to do, so I hooked its output up to the bias supplies of my Sound Lab 845PX speakers. To my moderate surprise, this proves to be beneficial. So far, I have done an ABAB experiment, which is to say I was used to the baseline sonics (A), then I added the PS Audio (B). Then I took the PS Audio out (back to A). Then I put it back in (B). This confirms to my one pair of ears that the regenerator helps. I do not live in an area with dirty power. I wonder if anyone else has had a similar experience and what you thought. Thanks.

I mentioned before about my Tripplite - Story 06:29:55 11/24/21 (2)
so I measured the voltage coming out and it was 111vac. I thought it was OK after the flood I had, it got a little wet, so I went inside to inspect it and there is one trimpot for adjustment and I could not get it to respond. No matter the turn, the voltage was always the same 111. I got another one out from the garage and it worked but the range only changes in 3 steps - 111, 121, and 129 so I didn't use it.

I have the ESL's plugged in to an isolation transformer for now which is plugged in to the Panamax. It will have to do for now but I did notice a difference and it's better anyway.

Cheers and have a happy

  Better with both than with Panamax alone?

    better? yes. How much? not a lot but I feel better having a fused I tranny just in case something bad happens

I use shielded "Asylum" cords and Tripp-Lite conditioners with the U-1s.

  Just got mine delivered...Are you using more than one for mono block amps?

    The Tripp-Lite units to which I refer are for the U-1 power supplies. It is the small white rectangular box at the outlet near the shadow.
    
    The amplifiers get a dedicated 20A line and a shielded Harmonic Technology Magic power cord. No conditioners for amplification devices.

      Sorry Stat: The only small white box has a 'power cord' resting on it. But I get the idea-you are not doing voltage regulation?

        I get it- My area is prone to intermittent voltage drops (lower east NYC) I have been using a TL surge protector(may cut the edge off the highs but that could be the result in the reduction of noise) but obviously that does not prevent the effects of voltage drops. Glad you do not have to deal with it-heard your speakers a while back and they are magnificent. Do you use any surge protection for amps and preamps? I gather you do not. Thanks UT
        Won't get playing with voltage regulator/conditioner to well after the holidays- If it does not work out no big deal.If I owned Sound Labs I would not add any conditioners either.

        Only what I posted. Here's the Tripp-Lite two outlet conditioner to which the backplate is plugged in:

I use a PS Audio P3 and have everything plugged into it. Makes a pleasant
difference.

- RE: AC power regenerator for ESL bias supply - Lew 12:48:08 11/20/21 (1)
  Mike, Thanks for your response. I am curious to know what is "everything"? As you know, the P3 has its limitations in terms of current it can supply, unless you use the two outlets that can be switched to act as filters only (not sourcing regenerated current/voltage). I guess if all your equipment is plugged into the P3, you cannot say for sure that the P3 is helping the bias supplies of your ESL. (Presumably your speakers are ESLs.)

    I don't have my Sound Labs yet, but plan to plug them into Shunyata power conditioner and distributor with their NR power cords. The power conditioners made a big difference on my front end and MA1s. According to Shunyata much of the noise that is filtered is from the components themselves (the SL back planes are basically linear power supplies).
not with a regenerator - Story 09:14:55 11/20/21 (12)
but I have a Tripplite regulator because the voltage around here is all over the place, especially in summer. I never thought there could be a diff.
- RE: not with a regenerator - Lew 12:49:29 11/20/21 (11)
  Thanks, Story. So in your opinion your Tripplite filter improves the sound of your ESLs. Is that fair to say?

    I did it for the protection from a lousy grid here in NJ with voltage vagaries. To compare I would have to try both like you did, but I feel better knowing the voltage setting on the 57's will be within a reasonable tolerance.

      I just ordered the Tripp Lite voltage regulator/conditioner in the 2400 series. I did not check to see if the amperage drawn from the Parasound A21 (2) would overwhelm the conditioner-- voltage regulator. I live in area where voltages swings intermittently 5-10% daily and recently lost my amps to extreme drops in voltage which the surge protectors I have were not designed to do. If there are sound differentiation , peeling of the highs with the advantage of a quieter and deeper sound stage , the choice is a no brainer. Protect equipment. The Parasounds are replacing previous amps that failed

        Years ago I had to buy what was locally the least expensive volt regulator, a Panamax TOTL at $700 at Best Buy. It works well enough keeping the voltage from 114-125 out of the wall. The display shows exactly what's coming in and what's going out and it works silently. It's not a 'tight 120v regulator' - they cost more, sometimes much more AFAIK. If there's a better one at that price I don't know. I consider it insurance.

        THE PANAMEX 5400 M is reasonably priced and superior to the unit I just purchased... Will rethink it. Thanks for the lead..

        I am going to stay with the unit I purchased; mixed views, on Amazon which probably means nothing. An incredible if does what it says. Thanks Story!

        I went for price with TRIPP Lite; Does what the Panamax does display and all but does power conditioning which may alter the sound..Have not tried it out. I had good luck with their better surge protectors with rfi and they made the sound stage quieter so I could play at lower volumes(I live in an apt) Do not really know but seems they take something off the top end. I have not tried this unit until I am certain if can handle the Parasound. If it does not work out it was not a big investment. It is there metal unit.

        I found on line that its steady state power consumption is 300W, but at peak power draw it can require something over 1000W AC input. This would still be OK if you plugged it into your 2400W Tripplite.

        Thanks Lew; I slowly began figuring it out-even when playing organ music loud I cannot reach those levels...Tripp Lite used essentially the same design for 20 years-...I do not have class D amps but I wonder if they would trip the TRIPP LITE because of their circuitry. I also would have to use the 20 a circuit..Older building so I only have one in the living room -usually used for AC. Probably could get by with the15amp circuits with some care.
        best, UT
