Clean AC power

AS an ex-pshrinck, I suggest you spend as much as possible, because you will need all of the placebo effect you can muster to miss any "noise".

I have been a long time believer in the benefits of AC regeneration. I used to find that I would get the best from my system late at night, especially in the Spring and Fall when the demand on the power grid was at a low point. For the last several years, I have had a PS Audio P20 in my system and regardless of what time of day or season, I get super clean power with a very low impedance-and my system sounds consistently great. This is a fantastic product and in addition to helping create an incredible sound stage and amazing micro detail, because of the low impedance and ability to deliver peak power, I don’t experience compression with loud complex musical passages that were a problem in the past. I have tried all kinds of filters and some very expensive conditioning products and I prefer the P20 hands down. One other point, I do have a dedicated 20 amp line with #10 gage shielded wire running to the P20.  Also, the AudioQuest Hurricane Power cords don't hurt.  I never believed in power cords having an tangible effect until I did some A/B with the AudioQuest Storm line.  Don't think I would drop $30K on the Dragons to outfit my system but any of the Storm series is highly recommended.  

Get a good dedicated lines.
Do not plug amp into filter box etc.
Go directly into the dedicated line outlet

Life-saving tip: If you see someone get hit by lightning or is otherwise electrocuted the lethality is due to the heart going into ventricular fibrillation. Therefore, you should check for a pulse and if absent, do a precordial thump, which is a fairly hard and sharp blow to the sternum. Do it once and check for a pulse and if there’s no pulse, do it again and check for a pulse. If there is still no pulse, start chess compressions and get help. If you are uncomfortable with a precordial thump, go directly to chest compressions after checking for a pulse.

I had an old power wedge & decided to try a conditioner to see if there was improvement.
I got an iFi power station with the two additional I purifiers.

It made a significant improvement in soundstage imaging, blackness & clarity. More improvement than I had expected.

I have reference level cables & I think that helped to realize the improvement.

Really glad I tried it cause the improvement it made in listening to just my MD102 tuner alone was worth it…
