In rash moment a couple of years ago, I bought three Tanquility Pods when they were on a three for the price of two offer. Not really expecting much improvement, I placed them under my Linn Klimax DSM and Exaktboxes. I was already using Isoacoustic Oreas and Mini Pucks so it was easy to create room underneath the components for the Pods.
I was sceptical about the Pods because of the many negative comments online regarding Synergistic Research. Also, the Klimax cases were made of solid aluminium so I doubted that the Pods could have any effect on the internal electronics. For that reason, I placed them near the rear panel where the external conections are made.
In fact, the Pods had a beneficial effect on sound quality. This is best characterised as a smoother sound not unlike the improvement from the Organik DAC upgrade.
This success prompted me to buy a fourth Pod that I saw advertised at a reduced price on eBay. However, I was disappointed that placing this additional Pod on my Roon ROCK NUC and my ethernet switch produced no discernable effect. The failure to have an effect on the switch surprised me particularly because I was able to get a nice improvement by upgrading it's power supply with an Sbooster BOTW.
Earlier this year, I got back into vinyl after a five year hiatus. I acquired a second hand Klimax LP12 that I had upgraded to current spec. To make room for the Pod underneath the Urika II phono stage in base of the turntable, I inserted an extra shelf of Baltic birch ply supported by height adjustable isolation spikes. Again, I feared that the aluminium Trampolin base of the turntable would block any possible beneficial effect from the Pod.
This fear proved to be unfounded. There was a similar improvement to the one I previously experienced with the DSM and Exaktboxes. Although I'd just done the Karousel and Radikal 2 upgrades a month earlier, I'd still been experiencing a slight harshness with some records. The Pod appears to have eliminated this completely.
I should say I have no idea how these Pods actually work. I find SR's explanations far from convincing. That's in stark contrast to Linn upgrades which always have a more than just plausible rationale. As I studied Physics to Post Grad level, that is somewhat perturbing for me. However, I am happy that they can have a beneficial effect as many others have reported.
I once was similarly bemused by an achitect who taught me how to sucessfully locate the route of an underground drain across my garden with a crude divining rod made out of a bent wire coat hanger. I assure you no illegal substances were involved.
