SmoothLAN Network Filter
Purify Your Music Streaming

"OK, the SmoothLAN filter is fantastic. The difference it makes is night and day. Internet radio has come alive. Vocals are crystal clear, midrange is definitely improved. As for bass, hold on to a seat. WOW. Reggae radio stations are fabulous sounding. SmoothLAN is an absolute winner. Radio stations sound bad enough, the SmoothLAN just sorts is all out wonderfully. 100% recommended. Octave radio sounds proper audiophile sound quality. The short fly lead could be a lot more flexible which is my only negative. Buy one with confidence. What a difference!"

"I love the SmoothLAN. I thought I'd have to do some A/B listening to appreciate it. Not so much. Immediately noticed more 3D in the high end, and a notable increase in instrumental separation and body. One ore step towards the LP12 sound from digital! Not too subtle, actually. You  guys are doing tweaks are 1/5 of the price of others with similar or better results!"

"Just a note to confirm that I have received smooth lan. It’s been installed into the Ethernet input in my recently aquired melco library streamer. I also had fibre broadband installed last week.

So my system is a little disturbed at the moment. I also want to let the smooth lan bed in. My link is also out of the mix at the moment as I mentioned, something I need to sort out.When you make changes you get alterations in the sound, they may not all be in the right direction. So before I added the lan smoother I could hear vocal sibilance on a couple of tracks that I play regularly. On balance it was something I accepted as a trade off for the more pinpoint three dimensional sound image.The problem track was the first I played. The vocal sibilance had disappeared! So I am delighted. So only positive improvements noticed at the moment. I will give it some time to bed in before I give it a more considered focused impression."

"Once the SmoothLAN was installed everything seemed to just be more open and free. The bass is so tight and everyting is just so crisp, it's delivering like a product worth 20 times its price, it's like when I swapped out the XPS DR for the 555PS DR, it's that good!"

“Very good filter that makes the music calm and allows details to be heard in a natural way.”

“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'm using the filter between an English Electric network switch (which I bought a few months ago) and a Bluesound Node X streamer, streaming mainly from Qobuz and Radio Paradise. The SmoothLAN 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.”

“Clearly 'works' and good value for money - both for streaming music and for streaming TV”

“I paired with the Volumio Rivo streamer with the Farad Super 3 power supply, which is fed with the new Roon Nucleus One. I noticed a tad bit better dynamics and better focus. I would purchase again.”

“I did not expect the SmoothLAN to work in my system since I only listen to music ripped to a Upnp server. I was wrong!

My system has never sounded better than with the SmoothLAN (and AUVA 100s and AUVA EQs).

It is a no brainier to try it in your system - I am delighted with the results.”

“My system/digital front end was already sounding good, and the SmoothLAN has made it just that much better. Instruments (especially piano/voice) sound more 'full' and in-the-room. The soundstage is more spacious, and there's less sense that the music is coming from the speakers.

At a very attractive price/performance point, I'd heartily recommend the SmoothLAN!”

“more punch, better instrument separation, and increased feeling that the music is outside the speakers”

“I guess cleaning up the noise allows more detail through and that manifests itself as much more detail in massed instruments, crisper fruitier brass, more clues about ambience more percussive piano notes, and quite a big difference in the bass”

“this is my second SmoothLAN as I bought my first for my Naim SN3 /NDX 2 + Roon Titan living room system in the spring. LOVE IT!”

“Bigger sounstage, both width and depth, instruments and vocals are placed in the sounstage so well.”

"The SmoothLAN arrived on Friday. I LOVED it! I could hear a significant difference with the SmoothLAN in my chain, without a doubt the best my system has sounded. I could hear much more transparency, the music sounded so clean, no fatigue while listening for a few hours... the music just sounded so much more natural and easy to listen to. You folks have created a gem, kudos."

“The sound improvement by the Audio Stack SmoothLAN is great. I'm able to compare the sound playing from a local starage with the sound by streaming from the Internet. Without the SmoothLAN it sounds better from local storage, but with the SmoothLAN it is considerably better when streaming from the Internet.”

“Just helps the music flow!

A beautifully constructed product from an innovative UK company that also has great customer support. If you own a DAC that is network connect - you need to listen to SmoothLAN!”

“on immediate use it makes the sound clean and clear that's the best short description also slightly darker background and slight increase in 3 dimensionality and sound stage, this definitely works I expect it to get better with run in thanks to stack audio”

“it seems to have opened up streamed music more giving a little more clarity and openness”

“Detail clarity, soundstage imaging, bass has tightened, and more space between each component of the music”

“It was easy to hear the improvement in my Qobuz streaming. A huge improvement for a small amount of money.”

“Glaringly obvious improvement in sound quality especially the sound stage. Much bigger and more open and lifelike.”

“Seemingly the SL has cleaned up an unforeseenly amount of artefacts derived from the digital domain, eliminating burdensome sibilance and fatiguing edgeness.”
