Today I share info on something I found out about MY SYSTEM that may help YOUR SYSTEM! For years I have been plagued by sound changes within my audio system for no reason. I have also had issues with transformer buzzing with some amps, but not all.
I have tried fixing this with rewiring my electric, buying a $10k power plant regenerator and various power conditioners. While the P20 PowerPlant did make my system sound the same 24/7 it did not fix all of my issues with electricity like some amps that still had a transformer buzz. After I had my room re-wired I sold my P20 as I figured I would no longer need it. I was WRONG!
When I found and tested the Puritan Audio PSM 156 this little black box broght back all of the magic to my system as well as bringing stability. This means it sounds the same 24/7 but now there is no more transformer buzzing as well! This magic black box truly helped my system proving that it all starts with POWER. Without it, my system sounds harder, harsher, flatter and with less fullness and sweetness. With it, there is magic and all of these issues vanish.
This is one of the best, if not the best HiFi purchase I have made to date.
Enjoy!

@bernardstachman3507 Год назад

This was convincing. Think I'm gonna buy it. Do you recommend connecting all equipment? Especially is there any problem connecting both digital and analogue devices to it - as opposed to some power strips that have separate zone for those (perhaps the outlets here are all separated zones to some extent)?

@user-xx2hj7xb6b 10 месяцев назад

I've found that the so-called difference in sound from one day to the next lies not in the system but in the listener. You touched on it here. Human beings are infinitely more complicated than audio systems. Moods, state-of-mind can change from day to day and that influences what we hear and how we hear it.

I’d be curious to know if this could help with ground loop hums between pre and power amps. I had to use an Ebtech Hum X ground line voltage filter in my preamp to eliminate a ground loop hum. Before this, I tried Niagara 1200 and AQ cables, but the hum was either loud at some times or barely noticeable other times.

Thank you. Very interesting. One question : have you changed all the power cords in your system ? Or did you keep the ones you had initially(for amplifier, sub, etc) ? Thanks.

@rickhigginson8546 Год назад

Even expensive units, are likely to have, "starter," power cords. I purchased better ones, recommended by PS Audio {the maker of the P 20 Power Rejuvenator}, specific to each piece of equipment, including more substantial ones for the power amps, & the P 20, itself. The quality power cords, and connectors, represent 15 to 20% of the cost of the system! Worth it, I feel, to try to maximize the quality of the system. It's interesting how different pieces of equipment, help in his particular situation ~

@carterleynes6380 Год назад

Don't underestimate the condition of your ears. Listen to a system after a couple of hours of driving and you'll notice how lifeless it sounds. Even worse, I once listened to my stereo after a plane ride and couldn't believe how quiet it was and how much bass it lacked. Oh and check for ear wax too.

I dont really get it to be honest. Room rewired, with such a top notch system and still sounding flat and noisy. Go figure! Whole thing saved by an obscure power purifier.

Great review and recommendation! My problem is with the harshness in vocals and cymbals. I own a Linn DSM 4 connected to a pair of FyneAudio 501 speakers.

Could this be the solution?.

@zackw4941 Год назад

Have you tried the Puritan with a nornal power cable yet? Logically, if the power conditioner is doing its job, the cable between the wall and conditioner shouldn't make much difference. On the other hand, cables between the conditioner and the equipment maybe more effective to preserve the clean power and reduce interference via shielding.

It’s not just DC offset. Most AC is filled with noise of all sorts from home appliances, computers, neighbors, and commercial buildings. It’s usually the worst during peak power usage during the day. That’s why it’s best to listen late at night when everyone is asleep.

@JohnLee-db9zt Год назад

The big issue I have with Puritan conditioner is all the inductors it uses to filter noise. I’ve used power conditioners like this before. It lowers the noise floor at the expense of restricted dynamics and truncated soundstage. This conditioner maybe different but I doubt it.

@2011RAIMONDS Год назад

You are absolutely right that some days sound is not perfect for the same system. Could it be depending on air pressure change?

Or if you have a cold that can effect the sound,plus if you sneeze and your ears pop slightly that too can change the sound.

@kostaspanousakis9953 4 месяца назад

Thank you for your thorough test! I wasn't aware of this brand. Have you ever tried a Furman conditioner in your system? I have been using their cheapest model (AC 210) and I very glad for the purchase, because it has brought a very noticeable improvement in my system. The system became silent and I can hear the background as being totally "black" (absolute lack of any kind of noise). There is also a model (P 1400 in Europe) which does what all the other conditioners do, plus it's also a voltage regulator. I was wondering how the puritan compares to any Furman conditioner. Thank you!

@slidetek Год назад

Thing is, you've introduced a new X factor by rewiring the room. You said you just plugged your amp straight into the wall, and the peripherals went into a power strip. First thing I'd do before plopping $4k into a new toy, would be to start from scratch. I'd be really interested to see what the Niagra does as far as alleviating your issue. Sure, this is 1/3 the price of the PowerPlant, but I'm guessing with the new wiring a lot has changed with your system. When I was building my dream room with a dedicated 20amp panel just for the electronics, they installed some sort of sine wave conditioner that wasn't particularly expensive. The noise floor was non existent, and the blackest of blacks. The ex probably has her electric piano plugged into it these days. BTW, after 50 years (25 as a recovering audiophile), I know half of it is psychological. There's days I just shouldn't be listening and don't. In my current digs w/lousy wiring, a Niagra solved my minor issues.

Nope, it isn't psychological.

@angelo4670 Год назад

The DC issue you’re describing is particular to toroidal transformers. EI core transformers don’t have this susceptibility to DC. My Yamaha AS2100 has an EI core, which is the only reason I know this. Toroids are used more often because they don’t emit as much of a magnetic field as EI’s. Properly implemented EI’s require shielding and more room in the chassis.

@LuxAudio389 Год назад

Luxman uses EI Transformers.

@angelo4670 Год назад

yes, you are correct. Perhaps Steve’s problem isn’t DC in his power lines. When I read about the pros and cons of EI transformers the main pro was lack of sensitivity to DC.

Lucky you. My old amp was humming happily in the background until I got an audio lab dc blocker thingy that brought that noise down to almost inaudible. Since then had four other apps on trial, Hegel 390, Gato Audio Amp-150, Luxman 700u and Accuphase e380. All hummed, the dc blocker worked on them all (never totally removing the transformer hum, but always at least halving) except for Luxman, which I actually bought but ultimately had to return for that reason. Luxman has an E type transformer, unlike toroids in the other three, and I read somewhere the dc blockers are not effective with those. What is puzzling a bit here is that the 595 is most likely also of the E type… Have I got a dodgy dc blocker that can’t cope with DC on my mains, i.e. lacking in that magic dust, or just unlucky with four respected brands and their expensive amplifiers?

Have you disassembled the outlet and made sure the wiring is properly attached? As in the screws holding the wiring to the outlet are tight? Do the same on the panel at the breaker, ground and neutral. Electricity vibrates, and will loosen connections over time. If you have the stab outlets, where the wire is stabbed into the body of the outlet, upgrade the outlet to a better quality one. Another thing you can do, is to drop a direct circuit to your electrical panel, 12/2 romex on a 20 amp breaker. If you have not done that, you should really consider doing it. It really made a difference in my system.

No more buzzing, much better sound and protection for the system. All you need to do is google “dc causing transformer buzzing” and you’ll find years of articles and info about it. It’s a thing.

System sounds the same 24/7, no noise, amps never buzz or make any hint of noise. It's a piece I would not be without at least as long as I live here.

I live in Mexico and Mains power is horrible. I had to install a large UPS for my home network media center. All my TV's and audio equipment have there own UPS. Voltage can swing 15 to 20 volts during the summer. The LED lights that I installed in my home insert horrible noise in the the Mains that I had to look for and locate better options. Power outages are not common but they happen when wind is high voltage spikes happen quite often. Rain always brings power failures but I have a power generator for outages.

My system always sounds fantastic. Must be my sansui AU 717. No Integrated amplifier 100 watts and under comes close.

you said you dimmed the lights. Dimmers can generate the hum you described

Thanks for making your points. It sounds exactly like beeing catched by the hi-fi religion this industry strives for, and that's both fun and engaging - as long it's lasts.

Yes, hifi is great fun! The hifi reviewers allways think they have found the hifi Jesus, but they are never happy!

@ricardocoloma-md Год назад

sounds like a dehumidifier would help also.

Barometric pressure will do it every time. Look it up. 😊

Your Willsenton R300 would have fixed the sound deficiencies. Tubes all the way. Hum is more likely a ground loop in the signal chain not a power supply issue. Any cheap amp power supply will filter AC noise.
