I bought a Tranquility and installed it on my LP12 a couple days ago. Ordered the unit from the UK. It was delivered to the West Coast in four days. Installation and adjustment took about an hour, which included reading the instructions a few times. The instructions were pretty clear, though not 100% accurate. FYI, if you buy a “Tranq,” the magnet assembly that is fitted to the inner platter is installed so that the screw heads are visible. The final thing to check is that there is no audible rubbing with the motor driving the table with an LP on it. Tiger Paw included a pair of film handling gloves, which is very thoughtful.
The sonic benefits are immediately audible and obvious. On the LP’s listened to so far there is better bass definition and detail, soundstage is wider, instruments and voices occupy their own space, highs and mids are clearer and sweeter, and overall the sound of the table is much faster and more dynamic. I could go on. Not sure if I would characterize my assessment as a “rave.” However, the results exceeded my expectations.
I think the Tranquility is a very good investment. I am very pleased with it. For context my turntable is an oldie... S/N 17XXX. No Cirkus, new belt, new oil, new bushings, Ittok arm with Cardas Clear wire direct to pre, Goldbug Medusa cart, Spec AP-UD1 mat. It’s great that the Tranquility can improve a 40 year-old table.
To the the issues raised in earlier posts... I suppose speed or slippage issues could be encountered if the lower magnet is not adjusted properly for normal operation. The platter assembly spun freely for several revolutions during setup of my system. Also the platter height did not change on my system after the Tranquility was installed. So I believe the bearing position remains unchanged.
I think the Tranquility works very well and represents very good value.
