Here is what people are saying about the Sony ALTUS S-Air Wireless Audio Transmitter / Receiver (ALT-A33PC)
5 Star Rating  "Sound Perfect! I am totally happy with ALT-A33PC!"

Sound Perfect!
I received my today and it works exactly the way I need!

I have a Sony BDV-IS1000 5.1 Blu-Ray receiver with S-Air Surrounding speakers.
In the beginning, I used a Sony TDM-NC1 Digital Media Wireless Audio Adapter (only works with Sony receiver with DM port) to connect my laptop to the receiver. I believe TDM-NC1 is in a very early stage of Sony wireless adapter development. It works but it requires re-pairing it to the laptop every time power it on or power the laptop on. And it drop connection from time to time. Also I can't make it streams the sound from IE. That means not sound from youtube, internet radio and all the new and fun things.

Second solution: I used a Sony TDM-BT1 Digital Media Port Bluetooth Adapter (only works with Sony receiver with DM port). It is better because it works like a "wireless speaker output" and can transmit any sound from my laptop to the receiver. So it works with IE, youtube and anything. But, still, I have to re-pairing it every time power it on or power the laptop on. Plus, it is super sensitive to any movement around my laptop. The music often drop when I am moving stuff around or one of the software running heavily...

Now, Sony finally gets it right. ALT-A33PC Wireless Audio Transmitter/Receiver (works with any receiver with RCA input) works right out of the box. I am listening to Internet radio now and no matter how I position the transmitter or even shaking it, the music is still playing with no hiccup!
Sound quality is virtually no different from running an audio jack wire to the receiver directly.
Of course, it supports only "analog stereo". But you don't have 5.1 quality on youtube or internet radio anyway.

I am totally happy with ALT-A33PC!

This is a great gadget. I am running windows vista on my desktop and have a sony receiver and this thing works great. Last year I was in my attic running speaker wire from my receiver (indoors) to my outdoor speakers. I was dreading getting back in the attic to run an RCA cable from my computer to my receiver. So my search started. I found this item and boy did it save me a lot of time. I received it yesterday and it took me about 10 min to get this thing up and running. I set mine up by the quick start directions that sony provides. You do not have to load the software sony gives you. I use iTunes with it and it workds great. I can sit on my patio and control my iTunes via my iPhone and relax. O yeah you can also control your volume via your iPhone. I will say that all these products are in close proximity so its hard for me to speak for someone that is trying to run this through out a 2 story house. But for what I need it to do it works flawlessly! The sound quality is very good too in my oppinion.

I had been looking around locally to hear the Sony Altus ALT-A33PC wireless system hooked up in a store for me to listen to. After being told the local vendors were out-of stock of the system and being told they had no idea when (if ever) any future deliveries would arrive, I found the system after a short search through At the time of my order, no reviews had been posted. However, my faith in the Sony brand led me to order a unit sight unseen and unheard. The delivery time was quite reasonable, however the set up of the equipment was not so clear from the instruction manual and software. After contacting Sony tech support, I finally got a connection from my Dell Vostro 220 computer running Windows XP in my upstairs office through to the Onkyo receiver and surround sound system downstairs in my den, an overall distance of 30 feet at the most. After maxing the sound output on my computer, the sound level heard through my downstairs equipment was only just as loud and audible in my den as if I had no wireless system at all and only listening music straight from my upstairs computer sound system. I was expecting something at least in audio quality as the CD player that is connected to my sound system, and the results were very disappointing. I found my self no better off with the equipment as I was without it.

A phone call the the other source vendor was made to request the return of the Sony equipment, in which the customer service rep was very understanding of the situation and provided me with a RMA authorization without any difficulty or hassle. I would have preferred to have kept the Altus ALT-A33PC if it had the performance that I should have expected from Sony.
