    2 things:

    1) Swapped out the right angle 10ft long, 18AWG power cable that came with the Martin Logan Dynamo Subwoofer for a Monoprice one that is only 6ft long and is 14AWG. What a huge difference! The amp must've been stifled. More bass articulation and resolution. Much more enjoyable. The Monoprice PC was something like $3. What is wrong with these manufacturers???

    2) Swapped out my iFi Mercury 0.5m USB cable for a 0.5m Pangea Premier SE. I'm disappointed so far but what a difference!! How anybody can say that USB cables can't possibly make a difference must have tin ears and a poorly resolving system. I will not give up on the Pangea's and will give them some break in time but it is plainly obvious that the Pangea is more restrained and warm while the iFi is fast, dynamic and bright. I don't know how that can't be better in anybodies book. The Pangea must be holding something back. I bought this because my buddy Steve brought a 1m long one and we both thought it sounded better overall although my opinion was that the highs weren't quite as good, whereas the bass was more resolving. Well I'm confused because unless breakin can make a huge difference I'm not caring for this brand new, shorter one.

    Now...explain to me in a way I might understand why the same principle shouldn’t apply to speaker cable and/or internal wiring? I realize we will have exceptions.

    I believe what I observed and others are observing with these large gauge power cables is that it is all about transient response and not about ampacity. That 18awg power cord has an ampacity of 10 amps and I only have a 200W amplifier in that Martin Logan Sub. 200W/120V = 1.75amps ! The 14awg pc has an ampacity of 18amps which some would cry OVERKILL OVERKILL! I've even heard people here say that 20amp runs from the breaker box are overkill for audio. I don't believe that's the case.

    I know you know you're preaching to the choir :) Gauge in speaker cables is very important in my book, especially for good bass. There's always diminishing returns at some point however. I have only tried 13awg 6ft and 14awg 5ft in my system and I haven't tried anything with lower DCR yet.

    PS: I do have future plans to fabricate another pair of 14awg 4N Ribbon Cables and parallel them right on the same binding posts on the speaker and amp and see what 11awg sounds like on my system. So many planned upgrades. It never ends but that's OK.

    The 3rd meter is probably for mic input.

    Actually :p -- it's apparently a dual-function meter, used to set the recording bias and also as some sort of dynamic range optimizer.

    I've got to say -- having just finished the speaker swap & returned them to their owner -- those GR Research Paradox 1s amazed me with their articulation, neutrality and seamlessness. I know that the "GR Research" guy (Danny Richie) is something of a polarizing figure... but I did very much like what I heard.

    Too bad that the tweeter that this particular model used is NLA.

    A couple of months ago,I set up a small streaming only system in our breezeway. Well, I got a little carried away and moved that system to our finished basement/ family room/ HT room,with a few changes. It now consists of a pair of Monarchy Audio sm70mkII’s,Graham Chartwell LS3/5’s,Promitheus Audio TVC,a Node 2,and a Beresford Bushmaster DAC,and a very inexpensive sub. To my ears,very satisfying sound. The room is pretty well insulated,so I am able to keep the volume just a little bit higher without bothering the mrs.

    I see your signature equipment list. :o You definitely have your own "Home Theater" for sure.

    I also have those Polk RTi12's in the back room, but I need to get those tweeters going again. But these RT3000Ps have impressed me from the first time I heard one. The concrete floor vibrated under my feet. :p
    Most people just listen to music and watch movies. I EXPERIENCE them.

    I moved my system to my main floor and tied in my Maggies. It had the opposite effect of what I was looking for; the soundstage shrunk!

    @maxward I can tell you right now the Elba 2 is going to have more slam than these. These dig plenty deep, but don't have that same level of impact. But they certainly dig deeper and fill in the bottom end where the Usher T515 couldn't reach. And they do so without any signs of becoming bloated or one note like my JBL Studio 580s would be, especially in a smaller room. At some point I might try some solid state power if I feel like these need a little more oomf, but right now I'm loving the balance in my 15 x 13(ish) room.

    The imaging and general smoothness of the top end is the biggest immediate difference. These really bring a new level of focus to the imaging that I haven't had before at home. And no particular part of the frequency range jumps out at me, which is a positive in my mind. Everything just transitions nicely as it should.
    I do think I still need to play with placement a little, but I expect these to be here for awhile. Probably focusing on sources and cables next. But no rush on any of that. I'm going to enjoy the system as is for awhile and let my wallet recover. :)

    During the summer,I set up a little system in our breezeway. A good portion of the time it was just to hot to sit out there. So,I moved the little rig down in our finished basement. AKA “The Pit”. It started out innocent enough. One thing lead to another,and this is what it has morphed into. It is just a streaming system.

    One plus for this system is I had the ceiling and walls well insulated,so sound doesn’t travel too much upstairs. I can listen at a decent level without disturbing the little Mrs.
