Which platform works best for you would likely depend on your specific rig, and the physical configuration of your room. Since my rack sits on a concrete slab, I obviously don’t have issues with floor-borne vibrations. If your room has a sprung floor, I would wager that the suspension of the Delos would make the IsoAcoustics more effective than the suspensionless Mitmat.

Both platforms delivered imaging benefits, but the Mitmat pulled slightly ahead here, helping to place instruments in space with just a little bit more precision. On the other hand, I found the dynamic improvements delivered by the Delos to be of tremendous value. Once I’d become accustomed to the need to adapt my listening levels, the Delos helped make the music jump out of the speakers in a most endearing manner.

But where the Delos soared was in its exceptional control of the bass and the bass-related oddities that infest the analog reproduction chain. For sound quality, you’ll have to make your own decision, as both platforms have their merits. But in my system, the Delos won out. And with its lower price, the Delos is also the winner for value.

I conducted three listening sessions, solo and with friends, going back and forth between pure Stromtank power and pure wall power. By the end of the longest listening session, I’d lost a pound moving six amplifiers back and forth.

Shortly after completing those tests, another issue arose. Nothing the folks in Germany tried could address a soft buzz that slowly grew from silence to an audible peak before buzzing down to silence, then repeating. Also, the unit would not recharge until it had discharged completely, and the row of LED charging indicators did not function properly. No amount of long-distance or on-site finagling could solve those problems.

With any type of cleaning process, whether it’s for dishes, cars, or records, it’s always important to ask yourself where the dirt is going. The problem with my childhood blue cleaning fluid and brush method was that the dirt mixed with the fluid to create a kind of slurry, which I then pushed around the record with the brush until the fluid evaporated, leaving most of the dirt behind. A vacuum-type cleaning machine suspends the dirt in the fluid, then sucks the fluid away, taking the dissolved gunk with it and leaving the record dry and clean. This is the basic principle behind all vacuum-type record cleaners, whether they’re the string-and-nozzle type like the Keith Monks or the slot-and-tube type still made today by VPI, Nitty Gritty, and now a host of other companies.

The PowerPlants have a significant input and output passive filter design, meaning they do not need additional filtering. Moreover, as PS Audio indicates, adding extra power conditioners to the input or additional filtering to its output may be undesirable.

As a variant to the standard sine waveform, the MultiWave function extends the peak charging time of the sine wave, so connected equipment has more energy storage and less power supply ripple. The result is a smoother sound with a larger soundstage than when using a simple sine wave
