That's a fair question and one I cannot answer. The only thing I know is that "people" say it's better to store wine in an environment that has no vibration. And, I know that a continuous vibration that would resonate, like that of a compressor, is the type of vibration that would cause more harm than a vibration that is non-consistent. One thing I can tell you is that mine sticks at 60-degrees and doesn't fluctuate...In that regard it has been perfect.
As to the 52-bottle thermo-transfer-thingy cooler that was $1600. Dude. Wow. That seems ridiculously expensive for 52 bottles. I could buy two 28-bottle Thermoelectrics for $500. If they last 5 years each, I would be able to go 15 years without spending a dime more than you did. All the more power to you if you had that much to spend on a 52-bottle cooler...I sure hope you are putting some pricey wine in there to "justify" its cost.
