Too many product make unrealistic claims. It's boring at best and quite troubling if a person falls for it by believing the story. This product defies any classification. Everything we list below are actual owner comments. 100% of the owner are in disbelief of its performance. - Mini Review by True Audiophile 

"A game changer
Better wear your diapers when you hear it 
I came in early and sat down to listen, only getting up to change the sides of the record. Three hours later I had to tear myself away and do some work dreaming of hearing it again
Far better than you told me, and you told me it was revolutionary. 
I am in utter shock, I cannot un-hear this thing
Its what I always dreamed playback could sound like"
Stereophile Review

“Stereophile’s policy of changing only one component at a time so that you know what’s responsible for the changes you hear is undoubtedly a good idea.

Sometimes, though, things just don’t work out that way, because reviewer systems and rooms are in a constant state of flux. Just as the S 1000 was settling in, a local contractor and friends found time to help me install A/V RoomService Poly-Flex Diffuser panels and some homemade slap-echo treatment. After these adjustments, I heard vastly improved image specificity and detail retrieval, smoothed rough edges on high-frequency sounds,and clarified soundstage boundaries and depth.

As I listened to Strauss’s Alpine Symphony and other works on our recent Recording of the Month, conductor Andris Nelsons’s Richard Strauss box set (24/96 WAV, DG 486 2049), even the softest instrumental lines were easily discernible amidst 90 instruments blasting away."

Czech Review

“Stromtank has been conceived to become an ultimate solution to clean power supply. It operates with no dependency on power grid quality, providing the purest possible voltage to electronics. It proves once again – and it does so in a rather unrivaled way – that it is the power foundation that lifts up the good systems to the great ones. 

Are the Stromtanks expensive? It´s relative. They were designed for audio systems – including power amplifiers – not only for front end components. Often we pay substantial amounts for filters or isolation transformers that only work on players and streamers, and are forced leave the amps on the ‘dirty’ grid not to lose dynamics and punch. Not with the Stromtanks. 

Also, one can deduct few thousand of Euro from the Stromtank’s price right away. This is the budget that would be necessary for a good power cord if another power conditioner should be acquired. There is the rule that the best power cord one can afford should be placed between the wall receptacle and the power center of a system. The Stromtank does not really care about the power cord that feeds it. It is only used for recharging the batteries, the components will not ever see it. An ordinary PC cord will do the service. In fact, as I mentioned earlier, the Stromtank can be completely disconnected from the power grid. Do it as an experiment but do not use it like that – I guarantee that once you will forget to plug it back in and the batteries will be drained. But the message is clear: your audiophile circuit breaker means nothing to the Stromtank. Spend your money elsewhere. 

However, the strongest argument for the Stromtank appeared in the introduction of this review: it is the power foundation which is essential and which lifts up the good systems to the great ones. In my opinion the Stromtank beats any power supply solution that is on the market today, active or passive. I’ve got to get one…”
