    Happy person Peter.finesound who has a 2 arm Orbe
    Once I had completed the suspension installation and replaced the arms and platter I did quick check just to see that all was in working order. By now it was well into the evening so I had a meal to prepare etc. so left the turntable. When I returned later I found that the suspension had “ settled” by a tiny amount ( we are probably talking seconds of arc here as the bubble level still had the bubble within the marked target area for a level setting but indicated a slight bias towards one side). I corrected this with the adjusters which , with the load of the arms and platter, were stiffer to turn than without it ( no surprise). I had a couple of similar tiny adjustments to make later but now all is completely stable. Oh, and the cutout in the motor housing now correctly aligns with the chassis position.



    The result is quite something. Compared ( from memory) to the old spring suspension the overall resulting sound is far more neutral. That is the natural timbre of instruments is better revealed and the difference between recordings from different sessions or record labels is more marked. Bass is not extended further( it was always good) but has gained pitch and detail. Background noise is zero except for any pressing or tape modulation noise etc. on the disc. Although the turntable has gained neutrality this is in no way sterile and the ability of the Orbe to communicate is enhanced not diminished. Likewise the wide and deep three dimensional soundstage is improved. In particular regarding the bass end of things, the sound no longer tends to clump around the speaker position. These are all details, though, compared to what I find is the main benefit. The overall stability of the sound reveals entire passages of music that had previously passed unnoticed. That is, what may have been a generalised, pleasant, orchestral wash of sound now attains form and structure giving it real meaning. This is a major achievement.
    One thing that I forgot to mention is the great reduction in audible wow that the lack of lateral movement of the chassis that the new suspension provides. In fact I have been trying discs that could bother me greatly due to being slightly off center with the old spring suspension exaggerating the effect. Now those same discs are easier to listen to with some of them now no longer providing audible wow ( it is no doubt still there for a meter to find but I listen with ears).

    I am absolutely knocked out with it.
    Best wishes

    3 little sorbothane pads have helped in stopping the microphone effect off the feet into the chassis , i suspect this would work with all the gyro /orbe decks ,

    I am next up once postie turns up with sorbothane, I am very interested to see if they work as I believe the vibration and microphone through the feet and into the chassis is a big issue with the gyro. It may not be so much with an Orbe due to the additional spider which the feet are fitted to and the upper spider having the pylons fitted to, obviously a Michel attempt at fixing the issue.

    I will report back on results once fitted.
    Listening is the act of aural discrimination and dissemination of sound, and accepting you get it wrong sometimes.

    Analog Inputs:

    Hitachi FT5500 mk2 Tuner

    Digital:-
    Audiolab 8300CDQ CDP/DAC/pre-amp

    Amplification:-
    AudioValve Sunilda phono stage,

    I think I am nearing audio nirvana, but donít tell anyone.

    the problem is the gyro uses the suspension to keep the feet on , i read an old review were they complained the feet caused noise to travel into the chassis, and you could hear if the platform was tapped into the chassis ,
    also i was told by a user Aejoker on his gyro if he tapped the chassis he could hear the tap through the speaker , The answer was simple in the end to isolate the small shaft in the split adjuster (upgrade system ) in the Michell pylon , what i did not expect was it works as well with the orbe if you have a split suspension , the older type on the orbe , does not have the feet on the suspension or the new type,
    Michell has decoupled the suspension in the orbe , But not on the Gyro , 3 little pads will help stop 90% , it was there when the springs where is use and still there when the new suspension was added due to the Michell design

    Waiting on a new switch for my table (I have a temporary switch in place) but when that comes in and is replaced and I rebuild the table I am going to give this new tweak a whirl.

    I have a Herbie's Audio Lab Super Black Hole here which I use rarely any more as I just don't listen to digital much at this stage. It is a dual layer mat consisting of a very thin top layer of carbon fibre on top of a similarly thin layer of silicone. Designed specifically to reduce vibration.

    So I've punched out and am ready to go. I also have an original Herbies Grungebuster CD Mat that I've also punched out. It is an extremely thin rubber material with a bit more adhesive on the underside and I may place a piece of that underneath the Black Hole material to prevent it from rotating or slipping underneath the ball bearing.

    Will report back with results when it happens.

    That looks interesting Blake. I guess you are putting these under the bearings on the pylons yeah?....looking forward to hearing about your findings Blake. I'm using the sorbothane provided by Peter and it is very effective..

    Yes, underneath the bearings. That's the plan.
