  • Wanna make your Arx sound a bit better? (a tweak)



    Just wanted to share a recent tweak I did to my Arx A5’s over the Holiday Season.

    It claimed to increase the speaker resolution for approx. $50 and I have to say it was pretty true to its claim.

    The tweak entailed replacing the stock binding posts with the Electra Tube Connectors.

    I became aware of this tweak from Danny Ritchie over at GR Research

    http://www.audiocircle.com/index.php?topic=137288.0

    I took the liberty of taking a few pictures during the whole installation process, just so one can get an idea of what is involved.

    I am very satisfied with the fit and finish of the final products, and again can honestly say that it did squeak out some extra resolution out of these already great speakers.

    Enjoy, Fred in Canada

    Interesting solution Danny has come up with here.

    I upgraded my cables a while back to Blue Jeans Cables Ultrasonically welded 10 awg White with WBT locking banana connectors and immediately noticed a similar difference (which I'll assume is via reduced impedance at the connector, and both joints within the cable).

    The idea of reducing the impedance at the connector is a sound one. I'm not sure I'd notice much difference over my ultrasonically welded BJC 10awg, but this would definitely be an improvement over std stranded bare wire.

    Jon, what's your take? I think this is interesting.

      Interesting. This holds with the theory that eventually led to Slinkylinks cables, a minimalist brand I used to import. The thinking is that where joints, materials, junctions, and even mass is concerned, less is more. Avoiding solder is also a sound idea, provided that no oxides creep into the now solderless connection. (Ancient wirewrap technology - which was the basis of the entire analog telephony industry for decades - used the cold-welded principle too.)

      Slinkylinks are very fine monofilament "cables" suspended in ~96% air, a superior dielectric than plastics. Silver made them conductive, and the whole assembly, which is featherlight, has very low electrical reactance, the properties that alter electrical response and with it, change the sound.

      Connectors were tubular spring banana type, completely hollow inside and therefore employing a sort of high density/low skin effect mode for current through the reduced metallic content, which seems to be just like these connectors.

      Maybe Chane should look into these for production speakers...

        Sorry for the late update BufordTJustice/Jon, but I just wanted to mention that Danny's Electra Tube Connectors replaced my existing Multi-Contact LS4 Banana Plugs, which were VERY similar in style, but were nowhere near as effective/sounded as good

        http://www.takefiveaudio.com/mall/shopexd.asp?id=850

        Buford, you're reviews/support for the original A5's in the past is the main reason I bought the AR5x-c's to begin with, so I owe you a debt of gratitude. They sound better every day and always amaze/never disappoint.

        Just an FYI: I have been fiddling a LOT with the Raspberry Pi's as a transport mechanism. I am VERY impressed with this low cost solution and I highly recommend investigating IF you’re interested in trying something different

          Thank you and I'm glad I could shed some light on a truly high quality product. The A5 is a fundamentally sound concept and it has no chinks in the armor. it punches above its weight, to be sure.

          I have actually been eyeballing some R-pi solutions. Which model/chipset/board did you use to build your ras-pi setup? Or did you buy a pre-made? I'm looking for an easier way to get hi-fidelity audio from my wireless devices to my main system.

          Thanks in advance for your info.

          Also, please update this thread with whatever listening impressions you have gathered from the installation of your new connectors.

            My Bad, I have been trying to login to this Forum unsuccessfully for the last week...with the wrong ID.

            Anyhoo....here's my response

            Buford, I have currently “made” approx. 4 Raspberry Pi Music Servers.

            3 used the Raspberry Pi 2. One used an external DAC, 1 used the Hifiberry Dac, and one used the Hifiberry Digi+.

            I’ve also recently bought the new Raspberry Pi 3, but am still having playback issues, with it.

            Here’s the link that explains what each of the above mentioned boards does

            https://www.hifiberry.com/

            I become aware of the Raspberry Pi solution about 6 months again, when I was investigating an alternative to my aging Squeezebox Touch.

            In short, for very little money you can get an Amazing Music Server AND Playback device.

            My current setup is as follows;

            Raspberry Pi 2, with Hifiberry Digi, coax connected to my Schiit Bifrost DAC. It has an 2TB external USB Music drive attached, where I store all my Music.

            I have installed Max2play on the Raspberry Pi;

            http://www.max2play.com/en/

            All of this is controller remotely from my Ipad using Squeezepad

            http://www.squeezepad.com/

            OR from my Iphone using iPeng

            http://penguinlovesmusic.de/

            Sonically, this config blows away my original Squeezebox Touch config, and with the above Apps installed, everything is at my finger tips at any given moment.

            I highly recommend getting your feet wet in this type of solution, as it simply is amazing once everything is working.

            As far as listening impressions, with the new Tube Connectors. I could immediately hear more “weight” to the Music. Lows were better, highs shimmered, everything across the board just sound a bit better. For the investment of money and time, I recommend this upgrade

            Hope this helps, Fred
