“I ended up at Stack Audio through Hans Beekhuyzen’s review. That’s where I bought the Auva 70 insolators for my Focal Sopra No.1. And the Auva Equipment Isolator CSA2 for my Accuphase E4000. This review from Hans resulted in a larger number of orders, but they did everything they could to ensure that I did not have to wait very long for my order and that I received a small compensation for the delay.

When my order was received, I installed the insulators with the utmost care. And then let it break in. After a weekend I must say that there is indeed an improvement in the details and the sound image.
I have a 30-day money back guarantee on my order, which is great that you can try a product for a few weeks, but I will definitely keep my order. I have a feeling they will sound even better after a few more days of playing. Stack Audio indicates 5 hours of playback time.”
