Stack Audio Opiniones 

Prompt shipping, excellent product...

The Stack Audio Smoothlan absolutely makes a HUGE difference in my system, well beyond the price asked for this little aluminum box. I emphasized the huge because I don't understand how a tiny couple of hundred dollar worth of metal box could possibly improve my streaming signal. The more I try to think about how this little box could possibly make a difference the more my head hurts, so I stopped trying to figure it out.
It is so obvious how the music sounds more lifelike, more realistic, it clearly does something! The reason I am so shocked is because this improvement in sound quality is in spite of the system already containing an etherregen with its own power supply, and an expensive audiophile ethernet cable with its own filter, into a high-end streamer/server/player into a high-end DAC. Crazy!

products that do not go unnoticed! everything goes in the direction of improving presence and taxation. the control adjustment and presence of the low range are impressive. the pre and post sales service and support is excellent! some problems with shipments to Italy, but promptly managed by the stackaudio team. Well done!

Hi, my personal experience with the company has been great! Staff is professional, helpful and caring. Very quick by mail and friendly. Products are excellent and extremely good in price range, great value for money.
Perfect.

Order shipped with 2 correct M6 threads and 6 of the wrong size. The error was addressed promptly but the replacements seemingly got delayed in shipping, any arrived a couple of weeks later.

I have a few products from Stack, worth every penny. Decent listening gains for the price with a quality look and feel. The smoothlan network filter is a good example, the improved sound stage and separation really impressed me

Customer satisfaction was above the norm. I had to wait a bit longer than usual because parts were on backorder at Stack Audio. Customer service was in constant contact with me letting me now what their situation was and they made it right by giving me a small discount, which I did not expect or asked for. Exceptional service...Now to the product - I have a sound nerd friend and we go back and forth with equipment we have, trading out the equipment in the sound rooms (his, mine) and the Auva's are a gamechanger in my system. I have a set of Zu Audio Union Supreme 6's. The most immediately noticeable change was the bass extension and loss of muddiness ( I'll call punch?). Instruments that produce lower tone registry suddenly focused in the soundstage and the timbre of any low register instrument was realistic. I said above "focused soundstage" above but I mean like having a set of good headphones on.

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.

Stack Audio deliver products that works as claimed.
Fast delivery and very good customer support.
Excelent website contains clear information regarding the products.
Easy ordering process.

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!
