    Turntable, I would be interested to see your impressions. In my system, it still retains that AC3 smoothness but adds much more harmonic density in the imaging. It does not match the 3 motor assembly performance which is a bummer. Here is the 3 motor pic:Name:  IMG_4307.jpg

    Hi, I also recently upgraded from Raven AC-1 to the Black Knight 3 motors unit. At least in comparison to 1 motor, there is no contest. However, I never tried the 3 separate motors configuration though as I don't have enough room on my Minus-K for 3 separate motors but just enough room to squeeze in 3 motors unit while keeping Minus-K balanced. I burrowed the 3 motors unit from a friend of mine to see if it would fit on my Minus-K and had a quick listen for an evening and it did not take much convincing that I want this upgrade motors. Mine finally arrived a week ago and I find it is a significant upgrade over one motor. The image is better focused, more detail and separation of instruments. The biggest improvement I found though is in the bass. Bass is tighter, a lot more detail, better attack.
    May be next year, I will have to save up for the copper platter but I will have to do something about the additional weight as it may go over Minus-K weight limit.

    Anymore comments on the TW triple motor unit now that it has been available for a while now. Long term users have your opinions changed?

    Hi, I have been living with the three motor unit now for several months and still think it's a huge step up from the single motor. Never heard the three separate motors in comparison though. In regard to what the three motor unit does there is not much to add to what Suteetat wrote two years ago:

    Only other comment I would maybe add to that is that the imaging has also become wider and deeper.

    I have read recently in an audio forum about someone who preferred the two motor to the three motors - but I do not remember who posted it anymore.
    There was a thread on Audiogon on it some years ago: https://forum.audiogon.com/discussions/why-three-motors

    I read that thread you mention. I believe they are talking about individual motors two vrs three, and not the triple motor like the Black Night version.

    One thing should be mentioned though: although the three motor unit is fortunately not much heavier than the single motor (think balancing air suspended platforms here) it is obviously much larger in diameter. So if you are using multiple tonearms on all four positions with the AC, like I do, you will find yourself not being able to run a 9" arm at the front left position anymore. The armboard just can't get close enough to the platter anymore because the motor housing is in the way. Having said that 12" arms are not a problem.

    I have owned an LP12/Lingo then a Michell Orbe SE, and now a TW Acustic Raven Two (since 2012). I have heard the Basis 2500 (years ago) when contemplating the Michell Orbe. I wasn't able to compare them side-by-side. I went with the Michell but maybe should have gone with the Basis. I bought a Raven Two to be able to go up from a Graham 2.2 to a Phantom. I really like the Raven Two and have never looked back. My only issue was the motor pulley was not cut well and after replacing it all was fine. I love the sound....seems like there is much less "mechanical noise" filtering back into the music. Some people call it a dark sounding table but I disagree. I am totally happy with it and don't see any "real" need to upgrade as yet. Though moving from a G 2.2 to the Phantom-S was a way bigger upgrade!
    You really have to hear them both to know what they sound like, though that is difficult to do with different arms, cart's, amps, etc. You will find lover and haters of each.
    I bought mine w/o a listen because all I had read was good and all made similar comments. I wanted a two arm capable TT but really needed a TT that could accept the Phantom. Also, I was always intrigued by suspension-less designs and their potential difference in sound.

    The BN platter upgrade is twice as heavy as the standard Raven AC platter coming in at 20kg's. The new bearing runs smoother is seems quieter than the old Raven bearing giving you a slightly more neutral presence with better "black" background.

    I am currently running the table with one motor and that seems to be a little more energetic in timing than with 3 motors. 3 motors was slightly more relaxed and larger soundstage. I will go back to 3 motors in a week or so to confirm. Only trouble with the 3 motors is with the heavy 20kg platter, it does take a while with some slippage for the motors to come up to speed, or you just use your hand to give them a helping hand. that is how freely the new bearing runs.

    And, the BN platter looks cool with all the copper - good homage to Micro Seiki :-)
    I finally got my BN platter today. Didn't have much time so far for listening but first impression is very good. I expected a lot to happen in the bass, which was the case, but actually the biggest improvement here was soundstaging and three-dimensionality, a bit of added natural timbre and detail thrown in for good measure. All in all it seems to be a worthwile upgrade for the Raven AC on par with the 3-motor upgrade.

    I would be interested to hear what experience others made who did the upgrade to the BN platter.
