Should Amps be plugged into a power conditioner?


Greetings,

After reading about the amplifier hum, it was mentioned that some knowledgeable people say NOT to plug an amp into a power conditioner. Plug it directly into a wall outlet. Thankfully, I do not have a hum issue, but am curious as to what others say about where to plug your amp into. 

Thank you!

I've been very happy with my 200 watt amp from Spectral plugged into an Equitech 2Q which is a "balanced power" unit.  I use very high level MIT Cables power cords to and from the Equitech and found a benefit with these MIT pc's. I would not be without the 2Q. My cities power is not excellent; as many others are not either. YMMV. I decided to buy the 2Q by an in-home trial. It was a no brainer on listening; but not cheap. 

Definitely directly into the wall… and preferably into a dedicated direct line. Perhaps some very unusual  amp / terrible power situation it would be better… but I have not experienced it or heard of it. 
 

My dealer recently brought over a conditioner specifically designed for just the amp. I wish I remembered the name… it was high end, you’d recognize the name. The audition lasted about a minute… although I spent more time with it. Definitely restricted dynamics. 

One of the most respected power conditioner and cable companies, Shunyata, specifically designs the Denali and Everest lines with both high current and low current zones. The high current zone is designed for pre and power amps.  The low current zones for digital components.  I use a Denali and plug my integrated amp into the high current  zone and do not get hum.  SQ is improved over directly plugging the integrated amp into the wall (quieter background, more detail, better bass definition, timbre,  imaging and staging). I do not hear any reduction in transient speed, leading edge, and there is better impact.  Well designed conditioners like Shunyata, Audience, Nagra, Etc. will bring improved SQ to high current components.  I would not chance plugging in any of my components directly into the wall and chance damage from surges.

I have found many with big transformers actually limit the dynamics 

Ansuz D3 totally different technologies using powered mini Tesla coils over 100 

and different type of sign  waves making a very substantial improvements 

add to this their digital Ethernet hub and some of their cables magical .

my brother currently has them and I have been part of demos vs some  much more expensive products and this range from Danish Audio Group is pretty special .

Borresen Xmodel Loudspeakers and The excellent AAvic integrated amps 

and Axxis entry level gear is very good and decent pricing. Well worth checking out.
