    Isolation on Suspended Circuitry

    Does isolation help bring the best out of sound in all cases?

    Many brands and designs exists. In particular I am interested in case work from solid billet, with suspended circuitry.

    First I am going to experiment with isolation on my phono amp constructed from billet aluminum, it has suspended circuitry, meaning the bottom cover where the feet affix has no circuitry adjoined to it, pop the cover and its a piece of essentially flat stock aluminum.

    Does vibration travel around the outside of the billeted aluminum to the attached bottom cover?

    Will isolation tighten up the sound?

    I will be using Stillpoint Ultra SS (Stainless Steel) and Nordost TC (Titanium Ceramic) Sort Cones

    As a general rule, I have used existing songs I considered reference, here I am going to use new music and record from my iPhone, post to YouTube and compare in order not to rely on memory as well as invite others to comment.

    In the interim, if anyone has any thoughts towards this, chime in.

    Re: Isolation on Suspended Circuitry

    Isolation = bad
    Dissipation = good

    Each electronic device creates energy at 50-60 cycles a second. That energy has to be able to be released (dissipated) or it goes BACK INTO the device. Give it two weeks of isolation and your system will sound like crap.

    I have experimented with a variety of products including Stillpoints, Nordost, Ansuz, Critical Mass, Magico, etc.

    I have found, hands down, the Critical Mass Center Stage 2 footers to be the absolute best - BY A LONG SHOT. They do take about 2 weeks to “settle” in your system, but after that, holy cow! Amazing. I purchased a boat load for my system at home and put them under EVERYTHING in my home system.

    The other products are all excellent as well. The Magico Q-POD’s actually make the most sense to me from a pure dissipation standpoint since the copper dissipates and transforms the energy into heat, but I just haven’t tried them. I have heard them in a customers system and they work beautifully and I KNOW what the MPODS and SPODS and APODS can do under speakers.

    I have also tried the Ansuz DARKZ and they worked well, as I imagine the Nordost Sortfut Cones will.

    I have found that the biggest differences are under the digital devices and preamp, but you can still realize gains from a Phonostage and amps.

    Hope this helps.

    Thanks Mike, I have no doubt Critical Mass are sweet, but I am more interested in how isolation works on suspended circuitry, mounted in solid billet.

    Re: Isolation on Suspended Circuitry

    How does the signal get in?
    How does the power AC or DC get in?
    How does the signal get out?
    Are these signals analog or digital?

    Speedskater - ?

    I am simply seeing how or if isolation makes a difference on suspended circuitry encased in solid billet. Maybe no one knows, and believe what they are told, just playing since I am at a point of now qualifying a few things to see if they had the impact I originally thought.

    Re: Isolation on Suspended Circuitry

    There is mechanical isolation and then there is electrical isolation.
    Electrical isolation is real tricky.
    Mechanical isolation of solid-state circuits doesn't get you anything.

    Sorry, I wasn’t clear in the subject line.

    I am talking specifically mechanical isolation.

    My comparison will begin with the Stillpoints Ultra SS and Nordost Sort Cones under the Phono Pre Amp.

    Re: Isolation on Suspended Circuitry

    Just how extremely loud do you play your records?
    Can vibrations and turntables be a problem? Yes.
    But not for solid-state components.

    Components with moving parts like CD/DVD players, hard drives, fans are a different story.

    So what is it that you are hearing in your system that you don’t like? Or, are you trying to figure out which solution you will use in a search for a problem?

    Short answer, nothing.

    I’m qualifying the impact of expensive footers in my application seeing if they really add anything when used with decent platforms.

    I’m loaded up with various lines from Stillpoints and Nordost. These are under all power distribution, servers and network gear with purpose.

    My system right now is over the top good, and have put a lot of effort to get it this way, now anyone with common sense would leave well enough alone but, this for me is a hobby as much as it is an enjoyment of music, I love both equally.
