Stack Audio Reviews 249

On the internet I had read and I had seen YouTube reviews. So I began searching for the website. I ended up with a question, on which the website gave me no answer. So I contacted Stack Audio. Once I had someone talking to me (no robot) I knew what I wanted to buy. When I subscribed to Stack Audio I could become a fine deal of paying 10% less! So I ordered. It took quite some time before it was delivered, in the meanwhile I had gotten an e-mail saying sorry for the delay. Screwing the stuff under my speakers I could not screw it, ;) because it was easier than with the IsoAcoustic material I had before. After delivery I was asked via an e-mail if everything was okay. I could send back if I was not satisfied with the result of my buy. That possibility is fine and the aftersale attention is much appreciated as well.

Fast delivery. Great product, excellent noise reduction, made my td124 sound distinctively better, better transparancy and silence, more detail, just more music.

I have a problem with the unstable sound stage (not sure how it is exactly called in English), the stage (sound volume and width) appears and disappears from time to time. I found that it is caused by the router problem but right now I cannot change it to a new one.
I have a streamer naim NDS connected to the router through a switch Cisco catalist 2960.
When I connected the SmoothLAN network filter between the switch and NDS, I did not hear any audible difference. Then I connected it between the router and the switch, and this time the stable sound was established and the problem disappeared.
Thank you for good product and excellent service.

I've a Stack Audio Link IU, Link II, Soprano LP12 and now the Link product. Always delighted - wonderfully engineered products and wonderful customer service!!

This is my second order from Stack Audio and I am very satisfied with the service and the products itself.

I love what they’ve done for my system, and I look forward to finding a little heavier weighted unit for my amplifiers

well designed, it works the sound using it between my Lumin U1 and network switch has improved clarity and space, very nice improvment

Recently bought a SmoothLANfilter directly from Stack Audio for use between an English Electric network switch (which I bought a few months ago) and a Bluesound Node X streamer, streaming mainly from Quboz and Radio Paradise.
The item was delivered swiftly and their customer service contacted me a few weeks later to see how was getting on.
The SmoothLAN filter is working well with the EE switch, building on the benefits that came with the EE switch, by increasing the transparency of recordings and detail definition. There also seems to be more soundstage depth.

These footers bring a natural presentation to the sound of the system. The more I add the better the result.

Great service including one-to-one email interaction with knowledgeable sales manager

I have purchased multiple items and have had nothing but an excellent experience. I purchase with full confidence knowing the products work well and have no risk if I am not satisfied with anything.

Josh and the team came through at Stack Audio. This is my 6th set to complete my system with equipment and speakers. You have heard all the qualities of Auva such as soundstage , depth, bass and I will add one more that I may have missed on the various testimonials is a lower background noise level

After my extremely positive experience with AUVA 70 loudspeaker isolators (see my other review here for reference) I literally sugar coated my system with a set of four AUVA EQs (CSA 3) under my 46kg heavy Musical Fidelity M8xi integrated amp. They have replaced Isoacoustics Orea Bordeaux isolators. I can only confirm what others have already said: the upgrade is worth every penny. Both the stereo image and instruments separation have improved. In my system the acoustic guitars in particular finally sound live-like. The background is as black as you can only imagine. As a result, even some micro details of a recording can be heard but with no fatigue. Finally, from the aesthetics perspective, Auva EQs are visually less intrusive (being shorter/ smaller in size vs. Oreas and black which makes them disappear completely during late afternoon/ night listening sessions. Auva EQs have only proved that good isolation is a must not only under the ususal vibration sensitive suspects: turntables or CD players. Again highly recommended!

Great experience, quick shipping, personnel contact with designer, a product that works and at a good price.

Having upgraded my system over the past 2 years to a place where I happy very happy with the sound quality I just happen to read on the Antipodes forum a number of customers who had used Stack Audio products with very positive results. Decided to order the EQ’s first which I put under my server and DAC and played a couple of reference tracks I know really well. The big difference is all the instruments are separated & with better clarity. I then decided to order the AUVA 100 for my speakers and all I can say is WOW- everything just sounds more natural and organic. Prior to ordering the products I was seriously considering upgrading my server however now I would say without hesitation they are equivalent to a component upgrade they are that good, I also tried both Stillpoints and Franc Fat Foots last year but didn’t come close to these at all fraction of the cost.
Would recommend 110%

I finally get to hear the actual quality of my components free of extraneous distortion. Happiness abounds.

Excellent products that work as stated and excellent customer service. Just try the products you will like them and if you don’t they offer easy return.

Great communication and product. Quick no-fuss delivery. Does exactly what it says and then some. Ended up ordering 3 sets

Smooth Lan Ethernet Filter
Great company, great service! I am 100% streaming with my system and have made great strides in quieting down noise with power supplies, switches, cables, and power conditioning yielding a much more resolving and musical result.
Having said that, the Smooth Lan was by far the biggest bang for the buck of anything I've used thus far. An amazing jump in fine details, soundstage, and depth. I use B&W 804D3s which can easily veer into overly bright territory if the synergy is not right, and unfortunately that was the case for me with this. I am a concert level piano tuner/tech so very sensitive to correct instrument timbre. I think most people could very easily overlook the minor quibbles I had with this device and be very happy.
I did try this on my neighbors' system (Revel/Yamaha) and had stellar improvement there with no brightness issues at all.
I ended up returning this, and Josh was very helpful and understanding and sent refund immediately upon receipt of the unit. All and all a pleasure to do business with this company, I'll definitely use and recommend them going forward.
Best, Steve

Stack Audio had quick responses to all of my questions, and didn't just give the quick one-line get lost response, but actually spent a lot of time detailing what I needed - perfect! The second I put the Equipment Isolators into my system, it was a NOTICEABLE difference!!! I'm already planning on additional orders, and can't wait to bring in the speaker Isolators.
