Hi I'm a retiree who took a leap of faith in a small business. I did extensive research on an affordable option for an audio streamer. Like a fair number of people in the hobby my age, I don't have extensive IT knowledge so a standard Pi based streamer wasn't an option. After reading this forum and others and seeing a long and complimentary YouTube video review from Hans Beekhuyzen, on the Stack Audio The Link Audio Streamer I contacted Theo of Stack Audio via email with product enquiries. He was very responsive in our extended dialogue, replying within 24 hours each time. He was very helpful and encouraging. I made a purchase and had a unit delivered to Singapore. The unit is very well constructed and setting it up was not difficult EXCEPT that it WON'T LOG into SPOTIFY. It streams from TIDAL and my PC and a USB drive beautifully. I have made repeated email requests for help from THEO and he does not help. He answers only after about a week or more saying he will respond the next day but never does. He has now stopped answering at all! As a retiree, funds for my hobby are hard to come by. I am deeply disappointed in Theo and his abysmal service attitude. I would warn off all potential buyers NOT to buy the Audio Link Streamer as it does not function correctly and worse still, the after sales service is non existent. There are many other alternatives out there, do yourself a favour and benefit from my experience; choose something else!
