Is my Esoteric DV-50S a keeper?

Hi Ziggy. I am not familiar with Esoteric equipment but the consensus is that it is just about the best. My feeling is you would be moving down in quality just to accomodate your reachable price of a conditioner. Please take a look at my ad for a Brick Wall surge protector/filter and go to Price Wheeler's website for further information. I have used their products in an $85k system including a Wadia front end & Avalon Eidolons. I downsized into a headphone system because I moved from a house into a condo. Currently, I am back into a house. I now have a modified Wadia 25 and use a Linn Ikemi as a transport. I am selling one of my 2 Brick Wall units for the reason specified in the ad. I am keeping the other one. Most of these so called high end filters use MOV's. You never know how many hits they took before they are useless as protection. Most of them also limit current. Also, they divert noise to ground rather than to the neutral (because of the MOV's). Eventually the line noise, through the ground, gets back into the chassis of all your other equipment. The Brick Wall units do not do any of these harmful things at a very reasonable price. A manufacturer must also have great faith in the continued functioning of their product if they provide a 10 year warranty. Just some food for thought here before you sell and buy some things you may regret.
