Stack Audio Reviews 249

The Smoothlan is great. It had a "calming" effect on the music. Debth and separation of instrument increased and vocals becane clearer and palpebale.

Fast delivery, good packaging but most inmortantly: good sound improvenent, no coloration. Good adjustability.

great service and communication

Great products of stack audio and very good price/ quality.

The AURA 100 is a fantastic product, hard to believe until you hear it! A small issue with my delivery was quickly and painlessly addressed to my full satisfaction.

Great interactions. Thanks for the recommendation.

I will say this. I was ready to execute a major upgrade by purchasing better equipment based on where I wanted to see improvements. I know the upgrade game means spending lots more for little gains. However, I bought the Auva 70's for my speakers and 3 Auva EQ's for my turntable. The improvements were so apparent that it renewed my appreciation for my current components. The Stack Audio technology provided me with a good balance and in my opinion, lots of money saved.

Shipping to Germany was done quick from a warehouse in the Netherland.

Josh and Theo ... thumbs up, keep on going.

Extraordinarily good support, astonishing products. I could test the Auva 50 und 100 as well as the Auva EQ in my setup. Finally I bought the Auva 100 and two sets of Auva EQ.

Good contact with manufacturer and good service.

Stack Audio Auva and EQ have a positive effect. It's hard to believe that decoupling can achieve so much.

Excellent Product and great Customer Service. Highly recommended!

Good product...good service, just wrong support bolts for speakers, in case I need them one day for my Focal speakers.... But I am not complaining...

My audio system has improved a lot.Better soundstage and depth,a blacker background and more silent.Much better bas control.The hights are more refined also.

My expectations were fully met.
Great improvement in sound quality.

I have bought some CSA feets. They work great under my power conditioner, switch ann streamer! Delivery within one week!

Surprisingly efficient products and first-class customer service. What more could you ask for?

Have the Stack eq under my tube amplifier and under my power conditioner. What a difference. More depth, more natural sounds, more open and more peace. Then I removed the set under the power conditioner and put it under my turntable. This was a real improvement. My records sound much better than my cds on my Teac cd player. Now saving for Stacks under my speakers.
