    Hi Col.

    Great news! - glad you find it a worthwhile upgrade.. All I need now is more interest, then I can possibly get the unit cost of the production kit into a competitive arena.

    Funny thing is I had unbelievable interest in the Sole LP12 sub chassis when I announced its birth but very little in comparison for the Rega counterweight upgrade, even after the majority of (EDIT read all) folk who've tried it have openly stated it is better performing than the Tecnoweight and easier to use/adjust too ! Strange old world.

    My target price for these was meant to be around the £80 mark for production kit based on a call off of 100 units. The pre prod kit you have there cost me just a little more than that in design/drawing/set up costs etc.

    Anyhow good to hear you like it.

    John R.

    Hi John,
    Well the AI Rega counter weight is Great I feel it make the RB250 a much better arm I really like the tracking improvement and tighter and deeper bass I think and feel it is a better counter weight than the Michell Tecnoweight and it help too make the RB250 a little better than my AudioQuest PT6/Jelco tonearm so if and when you start selling AI counter weight I want one.

    Hi All
    Part two
    Right
    Audio Origami Rega RB250/Ortofon 2M Blue Cart Rega Planner Three
    Right this time I used my own low slung brass Counterweight with which the end stub is just screw in to the arm thread so isnít de-coupled. So assumed by some this shouldn'tít work well I have news for you it works just fine using the same two Albums. as I did with the TD160/standard rega 251.Well the Bigger weightier wide sound stage was there in spades lots of space between instrumentsí on a Black background A very clean and focused sound I thought much better than the Thorens TD160 sd rega251 but this was still very good at this point I changed over two Johns Rega AI Counterweight and cued up Sadeís Album promises sat back to enjoy well it didnít take long thinking bloody hell thatís good the same Weighty and wide sound stage was there but this time the far left/right edges of the sound stage became more defined and were sharper and cleaner any blurring had gone it was like opening a window in front of you speakers
    And so to conclude this review johns Counterweight is an Audiophile upgrade to any rega arm and special with a J7 Audio Origami modded Rega RB250
    Top job John R

    Hi j7
    Yep I got my round low slung Brass counterweight of eBay I thought it was one of yours j7 but not so sure now it doesn'tít have the we flange at the threaded end which I think your has but is works well on AO RB250/ortofon 2m Cart rega 3 plinth will have to think about the AO treatment on the RB251

    John You play with your own rear end and leave the rest alone.

    My 250 is a bit of a hybrid, has the j7 foam and rewire and an OL tail end. Works well with G1042 and DL-110.

    Cheers j7 !

    Very encouraging to read that and coming from the acknowledged master of tonearms too !

    It does look quite good I agree, but what it imparts to the Rega arm is just wonderful as Col as recently found out , as have a few others before him.

    Batty and I are in dialogue via pm, I sure we can come to an agreement soon.

    Many thanks for your kind words j7

    Regards

    John R.

    First up fitted it to the standard rega RB251/ G1042 /TD 160B/ this made a big difference to the Standard RB 251 tightened up the bass and bringing out more of the fine detail of the instruments and vocals sounded more refined Albums used were Sade .s Promises Trace Chapmanís Album of same name ía much more airy sound with much better bass definition making it easy to follow
    I would have been happy using john Rs AI Rega counterweight in this setup but as it just happens I have a modded rega 3 and yes you guessed it a full moded j7 Rega RB250/2M Blue Cart first think I noted in this setup was that well definition bass again but this time it had dropped down an octave
    instruments had more space between them the sound stage became lower and wider this is where I can say everything became more involving like when you get that feeling of the hair standing up on the back of your neck if a system can do this to me well thatís a winner in my book so to sum up Johnís
    AI Rega counterweight is a worthy upgrade to your standard rega 251/250 and a Delight with a Rega moded RB 250 no question
    Just Like to thank JohnR for allowing me the chance to trial his AI Rega counterweight
