    I can only confirm that these speakers sounds really great.

    A pair of fine speakers indeed.

    And I know how heavy they are, I helped Mctwins to get them in the house.
    Luckily they were all OK in regards to the shipping damage.

    I love them

    They are not as bad as the DD66000/67000s to move around, but for their size they are surprisingly heavy... and thank goodness the packaging is ample to allow for that level of abuse!

    They certaily do show us that GT and the team know how to get great sound out from their great drivers. I do wish they were willing to go with real walnut veneer though. That vertical grained manufactured veneer is not my favorite.

    Well, I have to say that these speakers ROCK's , great detail in voices and the bass has a good grip and sounds firm and tight. The mid bass, specially the snaredrum and perccusion sounds tight as well. I love the pluck sound. It really hits you even on low volume level. I have not yet pushed them with high volume levels, soon I will, maybe this evening.

    Too me, I still really don't understand what this means "Break In" time , they sound good allready, if I had these for years.

    One thing is for sure, they are heavy to be moved around by one person. this is the only complaint I have with these speakers.

    Grats on some really nice loudspeakers.

    Break-in I'd say is not only the woofer resonance frequency that will lower a bit to its nominal after use, but also to an extent the mid/tweet and X-O components need burn-in. Would not be surprised if in comparison the lower end now might sound a bit one-notey and mid/highs possibly a tad shrill or closed in to how they should flesh out later. I had 2 pairs of 580's that did and my current 590's did, took about 2 weeks to really sound right. Other brand new speakers I've had as well, some less or more noticeable.

    No, I don't think it's just the ear becoming more familiar with the sound over time, or "getting used to" the sound.

    For instance, I can tell you that the Martin Logan CLS IIa sound completely awful when they're new. Other people that heard them at the time said the same thing...'geez, they don't sound very good', and so on. But they soon shaped up.

    You and audiohack are now officially on the top of my "hate" list of LH'ers.

    Have fun!

    Thanks!

    Maybe you are right here but the problem is for me is that I will forgett how it was sounding from the begining. But of course, it is better that the speakers sounds better and better instead of the other way around.

    Or, I think, it is due too my good room acoustics that the speakers sounds nice

    Hallo!

    I have been listening all evening today and for some reason it sounds better today. Maybe it is because I am a happy man.

    If you look at post 4, one can see that load impedance is around 10 ohms. The right coner of the screen where is say's "Amplifier settings". Notice that the picture is not so good but download it your computer so you can see it a little better.

    We have this as a reference and we can see later on if the impedance goes down to it's nominal level, 8ohm

    Amplifier settings, Average IMP. On the screen that says "Continuous"

    I DL'ed and expanded, but the pic is too low-rez to see the values. I'll take your word though.

    I'd be surprised if they didn't drop Ω a bit after sufficient time. Since you have that very handy interface, it'll be interesting if you keep us posted.

    I'm sure your acoustic treatments help a fair amount too. If they were mine, I'd run FM interstation noise through them continuously when I wasn't home, and when sleeping (with the door shut, ofc!).

    I don't envy any of you humping these beasts around, or the Everests, etc. even worse. Something about, 'we must suffer for our art...', right? haha



    Yeah that veneer. One of the first things I thought...well, they're not Avalons or Legacies... But then if I had the dosh for them in the first place, I might re-veneer them (is that a word?) if I thought they were keepers.
