Attention: 2 versions of power supplies in circulation!

I would actually put garkeinen full review here only briefly in advance: The speakers are in my opinion one of the few 2-speaker systems (without subwoofer), which nevertheless provides very good sound quality.

But my main point:

I bought my speakers on Amazon and had the first couple due to a ruptured diaphragm, etc. complain, because it started with loud high notes to buzz.
It went smoothly, promptly I had a new pair since.

ONLY: The new boxes had accompanied a completely outdated, vast, heavy, whirring and hot nascent power supply! This had not been the case with the predecessor.

The conversion process was unfortunately very slow and unsatisfactory with Amazon, because it is simply not possible before goods issue to check the goods short (whether an old or a new PSU model enclosed).
After a few misunderstood mails (keyword: an outsourcing) I had but luck and the new package was again equipped with a new power supply.

CONCLUSION: If you the power supply very difficult, large and appear of yesteryear: exchange it to, there is a newer power supply model in the newer batches!
